Description
技术领域Technical Field
本发明涉及辐射屏蔽技术领域，特别涉及一种可屏蔽电磁辐射的贴件。The invention relates to the technical field of radiation shielding, and in particular to a patch capable of shielding electromagnetic radiation.
背景技术Background Art
电磁辐射是以一种看不见、摸不着的特殊形态存在的物质。人类生存的地球本身就是一个大磁场，它表面的热辐射和雷电都可产生电磁辐射，太阳及其他星球也从外层空间源源不断地产生电磁辐射。Electromagnetic radiation is a substance that exists in a special form that is invisible and intangible. The earth where humans live is itself a large magnetic field. The thermal radiation and lightning on its surface can generate electromagnetic radiation. The sun and other planets also continuously generate electromagnetic radiation from outer space.
电磁辐射有一个电场和磁场分量的振荡，分别在两个相互垂直的方向传播能量，是一种复合的电磁波；日常生活中，在我们生活环境周边都有很多产生辐射的区域，如无线通讯、微波炉、电脑、高压线等；人体的器官和组织都存在微弱的电磁场，它们是稳定和有序的，一旦受到外界电磁场的干扰，处于平衡状态的微弱电磁场将遭到破坏，人体也会遭受损害。这主要是低频电磁波产生的影响，即人体被电磁辐射照射后，体温并未明显升高，但已经干扰了人体的固有微弱电磁场，使血液、淋巴液和细胞原生质发生改变，对人体造成严重危害，可导致胎儿畸形或孕妇自然流产；影响人体的循环、免疫、生殖和代谢功能等。Electromagnetic radiation has an oscillation of electric field and magnetic field components, which transmit energy in two mutually perpendicular directions. It is a composite electromagnetic wave. In daily life, there are many areas that generate radiation around our living environment, such as wireless communications, microwave ovens, computers, high-voltage lines, etc. The organs and tissues of the human body have weak electromagnetic fields, which are stable and orderly. Once disturbed by the external electromagnetic field, the weak electromagnetic field in equilibrium will be destroyed, and the human body will also be damaged. This is mainly the influence of low-frequency electromagnetic waves, that is, after the human body is exposed to electromagnetic radiation, the body temperature does not increase significantly, but it has interfered with the inherent weak electromagnetic field of the human body, causing changes in blood, lymph and cell protoplasm, causing serious harm to the human body, which can lead to fetal malformation or spontaneous abortion of pregnant women; affecting the circulation, immunity, reproduction and metabolic functions of the human body.
电子产品在播放视频或音频时，电子产品中的扬声器组件在工作时会产生电磁辐射，而现代人普遍习惯长时间地使用电子产品观看视频，因此当人体长时间受到电磁辐射的影响时，人体的健康会受到较大的影响；并且现有的防电磁辐射的材料一般使用硬质的防电磁辐射材料，硬质的材料并不便于根据使用环境进行折叠或者弯曲，会对用户的使用造成影响。When electronic products play videos or audio, the speaker components in the electronic products will generate electromagnetic radiation when working. Modern people are generally accustomed to using electronic products to watch videos for a long time. Therefore, when the human body is affected by electromagnetic radiation for a long time, human health will be greatly affected. In addition, existing anti-electromagnetic radiation materials generally use hard anti-electromagnetic radiation materials. Hard materials are not easy to fold or bend according to the use environment, which will affect the user's use.
发明内容Summary of the invention
本发明的目的是提供一种可屏蔽电磁辐射的贴件，具有可便于降低用户长时间使用电子产品播放视频或音频时所产生的电磁辐射，进而便于降低使用电子产品对人体健康的影响的优点。The purpose of the present invention is to provide a patch that can shield electromagnetic radiation, which has the advantage of being able to reduce the electromagnetic radiation generated when users use electronic products to play videos or audio for a long time, thereby reducing the impact of using electronic products on human health.
本发明的上述技术目的是通过以下技术方案得以实现的：一种可屏蔽电磁辐射的贴件，包括用于隔离电磁辐射且可受外力弯曲形变的电磁辐射屏蔽层，所述电磁辐射屏蔽层呈片状结构并包含有可形成涡流的介质；所述电磁辐射屏蔽层的一端覆盖有保护层，另一端设置有靠近于覆盖扬声器组件表面的安装面，所述安装面上设有用于粘贴固定于电子产品中扬声器组件所在表面的粘附层。The above technical purpose of the present invention is achieved through the following technical scheme: a patch that can shield electromagnetic radiation, including an electromagnetic radiation shielding layer for isolating electromagnetic radiation and being bendable and deformable by external force, the electromagnetic radiation shielding layer being in a sheet structure and containing a medium that can form eddy currents; one end of the electromagnetic radiation shielding layer is covered with a protective layer, and the other end is provided with a mounting surface close to the surface covering the speaker assembly, and the mounting surface is provided with an adhesive layer for being pasted and fixed to the surface where the speaker assembly is located in the electronic product.
通过采用上述技术方案，通过将电磁辐射屏蔽层粘贴固定于电子产品中扬声器组件所在表面，利用电磁辐射屏蔽的磁旁路原理，可有效地屏蔽扬声器组件在工作时产生电磁辐射围蔽于电子产品的壳体内，以便于降低用户长时间使用电子产品播放视频或音频时所产生的电磁辐射，进而便于降低使用电子产品对人体健康的影响。其次，利用电磁辐射屏蔽层可受外力弯曲形变的特点，可使得电磁辐射屏蔽层根据不同的应用环境，通过折叠或弯曲以使得电磁辐射屏蔽层更好地贴合于辐射源；粘附层可便捷地将电磁辐射屏蔽层应用于不同的电子产品上，进而便于提高电磁辐射屏蔽层的应用范围。By adopting the above technical solution, by sticking and fixing the electromagnetic radiation shielding layer on the surface of the speaker assembly in the electronic product, and utilizing the magnetic bypass principle of electromagnetic radiation shielding, the electromagnetic radiation generated by the speaker assembly during operation can be effectively shielded and enclosed in the shell of the electronic product, so as to reduce the electromagnetic radiation generated when the user uses the electronic product to play video or audio for a long time, thereby facilitating the reduction of the impact of using electronic products on human health. Secondly, utilizing the characteristic that the electromagnetic radiation shielding layer can be bent and deformed by external force, the electromagnetic radiation shielding layer can be folded or bent according to different application environments so as to better fit the electromagnetic radiation shielding layer to the radiation source; the adhesive layer can conveniently apply the electromagnetic radiation shielding layer to different electronic products, thereby facilitating the expansion of the application range of the electromagnetic radiation shielding layer.
本发明的进一步设置，所述电磁辐射屏蔽层的数量至少为两层，相邻所述电磁辐射屏蔽层之间通过连接层连接。According to a further configuration of the present invention, the number of the electromagnetic radiation shielding layers is at least two, and adjacent electromagnetic radiation shielding layers are connected via a connecting layer.
本发明的进一步设置，所述连接层为PET基材双面胶。According to a further configuration of the present invention, the connecting layer is a PET-based double-sided adhesive.
通过采用上述技术方案，PET材质为苯二甲酸乙二醇酯，该材料耐温性好、抗剪切性强，一般长期耐温100-125℃，短期耐温150-200℃；由于手机使用时会发热，而且电子产品中扬声器组件所产生的电磁辐射亦会产生一定的热量；因此，选用该PET材质作为连接相邻两个电磁辐射屏蔽层时，既可使得相邻两个电磁辐射屏蔽层牢固地连接于一起，还可有效地降低热量对相邻两个电磁辐射屏蔽层连接固定效果的影响，进而有效地本方案的使用寿命。By adopting the above technical scheme, the PET material is ethylene glycol terephthalate, which has good temperature resistance and strong shear resistance. Generally, it can withstand a long-term temperature of 100-125°C and a short-term temperature of 150-200°C. Since the mobile phone will generate heat when in use, and the electromagnetic radiation generated by the speaker assembly in the electronic product will also generate a certain amount of heat; therefore, when the PET material is selected as the connection between two adjacent electromagnetic radiation shielding layers, the two adjacent electromagnetic radiation shielding layers can be firmly connected together, and the influence of heat on the connection and fixing effect of the two adjacent electromagnetic radiation shielding layers can be effectively reduced, thereby effectively extending the service life of this scheme.
本发明的进一步设置，所述电磁辐射屏蔽层包括纳米晶屏蔽层或非晶屏蔽层，所述介质为纳米晶或非晶；所述纳米晶屏蔽层或非晶屏蔽层的数量至少为一层。According to a further configuration of the present invention, the electromagnetic radiation shielding layer comprises a nanocrystalline shielding layer or an amorphous shielding layer, the medium is nanocrystalline or amorphous; and the number of the nanocrystalline shielding layer or the amorphous shielding layer is at least one.
本发明的进一步设置，所述纳米晶屏蔽层是在530～580摄氏度范围内进行退火处理，且退火时间在30～120分钟内，并在退火完成后增加磁化处理后的初始磁导率为80000～120000且最大磁导率为120万的纳米晶屏蔽层；所述非晶屏蔽层是在380～430摄氏度范围内进行退火处理，且退火时间在30～120分钟内，并在退火完成后增加磁化处理后的初始磁导率为5000～8000且最大磁导率为50万的非晶屏蔽层。According to a further configuration of the present invention, the nanocrystalline shielding layer is annealed in the range of 530 to 580 degrees Celsius, and the annealing time is within 30 to 120 minutes, and after the annealing is completed, the initial magnetic permeability after magnetization treatment is increased to 80,000 to 120,000 and the maximum magnetic permeability is 1.2 million. The amorphous shielding layer is annealed in the range of 380 to 430 degrees Celsius, and the annealing time is within 30 to 120 minutes, and after the annealing is completed, the initial magnetic permeability after magnetization treatment is increased to 5,000 to 8,000 and the maximum magnetic permeability is 500,000.
通过采用上述技术方案，纳米晶屏蔽层和非晶屏蔽层具有最高磁导率性能，可使磁力线限制在磁场辐射屏蔽层靠近辐射源的一侧，进而防止扩散到屏蔽空间。纳米晶屏蔽层是一种高频磁导率高性能吸收的屏蔽材料，屏蔽范围覆盖低频、工频、射频、高频，是目前市场上最先进的吸波材料；非晶屏蔽层，非晶态合金作为在性能上优于传统材料的新型材料主要是利用磁旁路原理来引导场源所产生的电磁能流使它不进入空间防护区，凭借优异的性能在电磁屏蔽室、精密测量仪器、屏蔽涂料等方面得到了一定的应用，同时又具有很高的机械强度、好的韧性及耐磨性，成为使用最广泛的电磁屏蔽材料。By adopting the above technical solutions, the nanocrystalline shielding layer and the amorphous shielding layer have the highest magnetic permeability performance, which can limit the magnetic lines of force to the side of the magnetic field radiation shielding layer close to the radiation source, thereby preventing it from spreading to the shielded space. The nanocrystalline shielding layer is a high-frequency magnetic permeability and high-performance absorption shielding material. The shielding range covers low frequency, industrial frequency, radio frequency, and high frequency. It is the most advanced absorbing material on the market; the amorphous shielding layer, amorphous alloy, as a new material that is superior to traditional materials in performance, mainly uses the magnetic bypass principle to guide the electromagnetic energy flow generated by the field source so that it does not enter the space protection zone. With its excellent performance, it has been used in electromagnetic shielding rooms, precision measuring instruments, shielding coatings, etc., and at the same time has high mechanical strength, good toughness and wear resistance, becoming the most widely used electromagnetic shielding material.
本发明的进一步设置，所述纳米晶屏蔽层的层数为12层。According to a further configuration of the present invention, the number of layers of the nanocrystalline shielding layer is 12.
本发明的进一步设置，所述电磁辐射屏蔽层的层数为1～20层；所述纳米晶屏蔽层的单层厚度为26～28微米，所述非晶屏蔽层(34)的单层厚度为18～20微米。According to a further configuration of the present invention, the number of electromagnetic radiation shielding layers is 1 to 20; the single layer thickness of the nanocrystalline shielding layer is 26 to 28 microns, and the single layer thickness of the amorphous shielding layer (34) is 18 to 20 microns.
通过采用上述技术方案，在该层数范围内，可使得电磁辐射屏蔽层具有较佳的电磁辐射屏蔽效率的同时，还可使得电磁辐射屏蔽层不至于完全屏蔽手机所发射的信号，以降低对手机使用过程的影响，还可有效地降低电磁辐射对人体的影响。不仅可使得纳米晶屏蔽层和非晶屏蔽层具有良好的电磁辐射屏蔽效率，还可使得其柔软性好的特点，制作成可卷收的片状，具有结构简单，轻薄，柔软，可卷起，人工易操作的特点。By adopting the above technical solution, within the range of the number of layers, the electromagnetic radiation shielding layer can have a better electromagnetic radiation shielding efficiency, and the electromagnetic radiation shielding layer can also prevent the signal emitted by the mobile phone from being completely shielded, so as to reduce the impact on the use of the mobile phone, and can also effectively reduce the impact of electromagnetic radiation on the human body. Not only can the nanocrystalline shielding layer and the amorphous shielding layer have good electromagnetic radiation shielding efficiency, but also can have good softness and be made into a rollable sheet, which has the characteristics of simple structure, lightness, softness, rollability, and easy manual operation.
本发明的进一步设置，所述电磁辐射屏蔽层包括若干层纳米晶屏蔽层和若干层非晶屏蔽层，所述纳米晶屏蔽层堆叠于非晶屏蔽层之间或粘附于所述非晶屏蔽层的一侧，所述纳米晶屏蔽层与非晶屏蔽层之间通过连接层连接。According to a further configuration of the present invention, the electromagnetic radiation shielding layer comprises several layers of nanocrystalline shielding layers and several layers of amorphous shielding layers, the nanocrystalline shielding layers are stacked between the amorphous shielding layers or adhered to one side of the amorphous shielding layers, and the nanocrystalline shielding layers are connected to the amorphous shielding layers via a connecting layer.
通过采用上述技术方案，通过将可屏蔽高频磁场辐射的纳米晶屏蔽层和可屏蔽低频磁场辐射的非晶辐射屏蔽层相结合，可有效地提高电磁辐射屏蔽层屏蔽电磁辐射的范围，以便于实现有效地提高屏蔽电磁辐射的效率，进而降低电磁辐射对人体健康的影响。By adopting the above technical scheme, by combining a nanocrystalline shielding layer that can shield high-frequency magnetic field radiation and an amorphous radiation shielding layer that can shield low-frequency magnetic field radiation, the range of electromagnetic radiation shielding by the electromagnetic radiation shielding layer can be effectively improved, so as to effectively improve the efficiency of shielding electromagnetic radiation, thereby reducing the impact of electromagnetic radiation on human health.
本发明的进一步设置，所述电磁辐射屏蔽层包裹于所述保护层的内侧。According to a further configuration of the present invention, the electromagnetic radiation shielding layer is wrapped inside the protective layer.
通过采用上述技术方案，保护层可用于保护电磁辐射屏蔽层，以降低电磁辐射屏蔽层受到物理损伤的几率，进而便于提高电磁辐射屏蔽层的使用寿命，其次，保护层还可供用户设置个性化的图案。By adopting the above technical solution, the protective layer can be used to protect the electromagnetic radiation shielding layer to reduce the probability of the electromagnetic radiation shielding layer being physically damaged, thereby facilitating the improvement of the service life of the electromagnetic radiation shielding layer.

具体实施方式DETAILED DESCRIPTION
以下结合附图对本发明作进一步详细说明。The present invention is further described in detail below in conjunction with the accompanying drawings.
实施例一：如图1所示，一种可屏蔽电磁辐射的贴件，包括用于隔离电磁辐射且可受外力弯曲形变的电磁辐射屏蔽层3；电磁辐射屏蔽层3呈片状结构并包含有可形成涡流的介质5；利用高电阻率的金属材料中产生的涡流，形成外来电磁波的抵消作用达到屏蔽的效果。电磁辐射屏蔽层3的一端覆盖有保护层1，另一端设置有靠近于覆盖扬声器组件表面的安装面31，安装面31上设有用于粘贴固定于电子产品中扬声器组件所在表面的粘附层4，粘附层4为3M双面胶；外露面32上设有保护层1，保护层1包括用于印刷图案的3M单面胶、以及附着于上述单面胶表面的滴胶层11，滴胶层11的外表面形成有可粘附于光滑平面上的粘附面12。滴胶层11由本技术领域常用的滴胶技术制成，如环氧树脂水晶滴胶，环氧树脂水晶滴胶后的制品表面会自然形成有可粘附于光滑平面上的粘附面12。滴胶层11可便于保护电磁辐射屏蔽层，其次，当电磁辐射屏蔽层通过粘附层固定于手机上，电磁辐射屏蔽层于手机成一体，此时可将滴胶层11的粘附面12贴合于光滑塑料的表面或玻璃表面，可便于手机的临时固定，进而便于用户使用手机进行行车导航等。保护层1与外露面32通过连接层2连接。Embodiment 1: As shown in FIG1 , a patch capable of shielding electromagnetic radiation includes an electromagnetic radiation shielding layer 3 for isolating electromagnetic radiation and capable of bending and deforming under external force; the electromagnetic radiation shielding layer 3 is in a sheet structure and contains a medium 5 capable of forming eddy currents; the eddy currents generated in the metal material with high resistivity are used to form an offsetting effect of external electromagnetic waves to achieve a shielding effect. One end of the electromagnetic radiation shielding layer 3 is covered with a protective layer 1, and the other end is provided with a mounting surface 31 close to the surface of the speaker assembly. The mounting surface 31 is provided with an adhesive layer 4 for pasting and fixing on the surface where the speaker assembly is located in the electronic product, and the adhesive layer 4 is a 3M double-sided adhesive; the exposed surface 32 is provided with a protective layer 1, and the protective layer 1 includes a 3M single-sided adhesive for printing patterns, and a drip glue layer 11 attached to the surface of the single-sided adhesive, and the outer surface of the drip glue layer 11 is formed with an adhesive surface 12 that can adhere to a smooth plane. The glue layer 11 is made by glue dripping technology commonly used in the technical field, such as epoxy resin crystal glue dripping. After epoxy resin crystal glue dripping, the surface of the product will naturally form an adhesive surface 12 that can be adhered to a smooth plane. The glue layer 11 can be convenient for protecting the electromagnetic radiation shielding layer. Secondly, when the electromagnetic radiation shielding layer is fixed on the mobile phone through the adhesive layer, the electromagnetic radiation shielding layer and the mobile phone are integrated. At this time, the adhesive surface 12 of the glue layer 11 can be attached to the surface of a smooth plastic or glass surface, which can facilitate temporary fixation of the mobile phone, and then facilitate users to use the mobile phone for driving navigation, etc. The protective layer 1 is connected to the exposed surface 32 through the connecting layer 2.
保护层1可用于保护电磁辐射屏蔽层3，以降低电磁辐射屏蔽层3受到物理损伤的几率，进而便于提高电磁辐射屏蔽层3的使用寿命，其次，保护层1还可供用户设置个性化的图案。保护层1靠近电磁辐射屏蔽层3的侧面面积大于电磁辐射屏蔽层3靠近保护层1的侧面面积，既可使得保护层1尽可能地覆盖电磁辐射屏蔽层3，还可降低电磁辐射屏蔽层3与外界发生物理碰撞的几率，以降低人体与电磁辐射屏蔽层3发生刮碰的几率，进而提高本方案的安全性。The protective layer 1 can be used to protect the electromagnetic radiation shielding layer 3 to reduce the probability of the electromagnetic radiation shielding layer 3 being physically damaged, thereby facilitating the improvement of the service life of the electromagnetic radiation shielding layer 3. Secondly, the protective layer 1 can also be used by the user to set a personalized pattern. The side area of the protective layer 1 close to the electromagnetic radiation shielding layer 3 is larger than the side area of the electromagnetic radiation shielding layer 3 close to the protective layer 1, which can not only make the protective layer 1 cover the electromagnetic radiation shielding layer 3 as much as possible, but also reduce the probability of the electromagnetic radiation shielding layer 3 physically colliding with the outside world, so as to reduce the probability of the human body and the electromagnetic radiation shielding layer 3 being scratched, thereby improving the safety of this solution.
通过将电磁辐射屏蔽层3粘贴固定于电子产品中扬声器组件所在表面，利用电磁辐射屏蔽的磁旁路原理，可有效地屏蔽扬声器组件在工作时产生电磁辐射围蔽于电子产品的壳体内，以便于降低用户长时间使用电子产品播放视频或音频时所产生的电磁辐射，进而便于降低使用电子产品对人体健康的影响。其次，利用电磁辐射屏蔽层可受外力弯曲形变的特点，可使得电磁辐射屏蔽层3能根据不同的应用环境，通过折叠或弯曲以使得电磁辐射屏蔽层3更好地贴合于辐射源；使用粘附层4可便捷地将电磁辐射屏蔽层3应用于不同的电子产品上，进而便于提高电磁辐射屏蔽层3的应用范围。By sticking and fixing the electromagnetic radiation shielding layer 3 on the surface of the speaker assembly in the electronic product, and utilizing the magnetic bypass principle of electromagnetic radiation shielding, the electromagnetic radiation generated by the speaker assembly during operation can be effectively shielded and enclosed in the housing of the electronic product, so as to reduce the electromagnetic radiation generated when the user uses the electronic product to play video or audio for a long time, thereby facilitating the reduction of the impact of using electronic products on human health. Secondly, utilizing the characteristic that the electromagnetic radiation shielding layer can be bent and deformed by external force, the electromagnetic radiation shielding layer 3 can be folded or bent according to different application environments so that the electromagnetic radiation shielding layer 3 can be better attached to the radiation source; using the adhesive layer 4, the electromagnetic radiation shielding layer 3 can be conveniently applied to different electronic products, thereby facilitating the improvement of the application range of the electromagnetic radiation shielding layer 3.
电磁辐射屏蔽层3的数量至少为两层，相邻电磁辐射屏蔽层3之间通过连接层2连接。电磁辐射屏蔽层3包裹于保护层1的内侧The number of electromagnetic radiation shielding layers 3 is at least two, and adjacent electromagnetic radiation shielding layers 3 are connected by connecting layers 2. The electromagnetic radiation shielding layer 3 is wrapped inside the protective layer 1.
电磁辐射屏蔽层3的层数为1～20层，在该层数范围内，可使得电磁辐射屏蔽层3具有较佳的电磁辐射屏蔽效率的同时，还可使得电磁辐射屏蔽层3不至于完全屏蔽手机所发射的信号，以降低对手机使用过程的影响，还可有效地降低电磁辐射对人体的影响。连接层2为PET基材双面胶，该PET材质为苯二甲酸乙二醇酯，该材料耐温性好、抗剪切性强，一般长期耐温100-125℃，短期耐温150-200℃；由于手机使用时会发热，而且电子产品中扬声器组件所产生的电磁辐射亦会产生一定的热量；因此，选用该PET材质作为连接相邻两个电磁辐射屏蔽层3时，既可使得相邻两个电磁辐射屏蔽层3牢固地连接于一起，还可有效地降低热量对相邻两个电磁辐射屏蔽层3连接固定效果的影响，进而有效地本方案的使用寿命。The number of layers of the electromagnetic radiation shielding layer 3 is 1 to 20. Within this range of the number of layers, the electromagnetic radiation shielding layer 3 can have a better electromagnetic radiation shielding efficiency, and the electromagnetic radiation shielding layer 3 can not completely shield the signal emitted by the mobile phone, so as to reduce the impact on the use of the mobile phone, and can also effectively reduce the impact of electromagnetic radiation on the human body. The connecting layer 2 is a PET-based double-sided adhesive. The PET material is ethylene glycol terephthalate. The material has good temperature resistance and strong shear resistance. Generally, it can withstand a long-term temperature of 100-125°C and a short-term temperature of 150-200°C. Since the mobile phone will generate heat when in use, and the electromagnetic radiation generated by the speaker assembly in the electronic product will also generate a certain amount of heat; therefore, when the PET material is selected as the connection between two adjacent electromagnetic radiation shielding layers 3, the two adjacent electromagnetic radiation shielding layers 3 can be firmly connected together, and the influence of heat on the connection and fixing effect of the two adjacent electromagnetic radiation shielding layers 3 can be effectively reduced, thereby effectively extending the service life of this solution.
电磁辐射屏蔽层3包括纳米晶屏蔽层33或非晶屏蔽层34，介质是纳米晶或非晶，纳米晶屏蔽层33为铁基纳米晶带材，非晶屏蔽层34为铁基非晶带材。非晶带材和纳米晶带材具有高磁导率性能，可使磁力线限制在屏蔽体内部，防止扩散到屏蔽空间，且这两种带材可加工至厚度最薄，且厚度越薄非晶化程度越高，且本身具有良好柔韧性。纳米晶屏蔽层33或非晶屏蔽层34的数量至少为一层。The electromagnetic radiation shielding layer 3 includes a nanocrystalline shielding layer 33 or an amorphous shielding layer 34, the medium is nanocrystalline or amorphous, the nanocrystalline shielding layer 33 is an iron-based nanocrystalline ribbon, and the amorphous shielding layer 34 is an iron-based amorphous ribbon. The amorphous ribbon and the nanocrystalline ribbon have high magnetic permeability performance, which can limit the magnetic lines of force inside the shielding body to prevent diffusion into the shielding space, and these two types of ribbons can be processed to the thinnest thickness, and the thinner the thickness, the higher the degree of amorphization, and the ribbons themselves have good flexibility. The number of the nanocrystalline shielding layer 33 or the amorphous shielding layer 34 is at least one layer.
如图9和图10所示，图9为层数为4层的铁基纳米晶带材叠加后对电磁辐射屏蔽效率的附图，图10为4层的铁基非晶晶带材叠加后对电磁辐射屏蔽效率的附图。其中，SEdb为屏蔽效能的对数表示方式(单位为dB)、SE％为屏蔽效能线性表示方式(单位为％)、P1为测试夹具中不放置电磁辐射屏蔽层3时频谱分析仪读数(单位为dBm)、以及P2为测试夹具中放置电磁辐射屏蔽层3时频谱分析仪读数(单位为dBm)。As shown in Figures 9 and 10, Figure 9 is a diagram showing the electromagnetic radiation shielding efficiency of four layers of Fe-based nanocrystalline strips stacked together, and Figure 10 is a diagram showing the electromagnetic radiation shielding efficiency of four layers of Fe-based amorphous strips stacked together. Wherein, SEdb is the logarithmic representation of shielding effectiveness (in dB), SE% is the linear representation of shielding effectiveness (in %), P1 is the spectrum analyzer reading when no electromagnetic radiation shielding layer 3 is placed in the test fixture (in dBm), and P2 is the spectrum analyzer reading when the electromagnetic radiation shielding layer 3 is placed in the test fixture (in dBm).
纳米晶屏蔽层33的单层厚度为26～28微米，非晶屏蔽层34的单层厚度为18～20微米。不仅可使得纳米晶屏蔽层33和非晶屏蔽层34具有良好的电磁辐射屏蔽效率，还可使得其柔软性好的特点，制作成可卷收的片状，具有结构简单，轻薄，柔软，可卷起，人工易操作的特点；并且，当纳米晶屏蔽层33和非晶屏蔽层34受到外力发生弯曲形变时，对其自身的电磁辐射屏蔽效率影响较低，可使得电磁辐射屏蔽层3仍具有良好的电磁辐射屏蔽效率。The single layer thickness of the nanocrystalline shielding layer 33 is 26 to 28 microns, and the single layer thickness of the amorphous shielding layer 34 is 18 to 20 microns. Not only can the nanocrystalline shielding layer 33 and the amorphous shielding layer 34 have good electromagnetic radiation shielding efficiency, but also can be made into a rollable sheet with good softness, simple structure, lightness, softness, rollability, and easy manual operation; and when the nanocrystalline shielding layer 33 and the amorphous shielding layer 34 are bent and deformed by external force, the electromagnetic radiation shielding efficiency thereof is less affected, so that the electromagnetic radiation shielding layer 3 still has good electromagnetic radiation shielding efficiency.
纳米晶屏蔽层33是在530～580摄氏度范围内进行退火处理，且退火时间在30～120分钟内，并在退火完成后增加磁化处理后的初始磁导率为80000～120000且最大磁导率为120万的纳米晶屏蔽层33；非晶屏蔽层34是在380～430摄氏度范围内进行退火处理，且退火时间在30～120分钟内，并在退火完成后增加磁化处理后的初始磁导率为5000～8000且最大磁导率为50万的非晶屏蔽层34。The nanocrystalline shielding layer 33 is annealed in the range of 530 to 580 degrees Celsius, and the annealing time is within 30 to 120 minutes, and after the annealing is completed, the initial magnetic permeability after the magnetization treatment is increased to 80,000 to 120,000 and the maximum magnetic permeability is 1.2 million. The amorphous shielding layer 34 is annealed in the range of 380 to 430 degrees Celsius, and the annealing time is within 30 to 120 minutes, and after the annealing is completed, the initial magnetic permeability after the magnetization treatment is increased to 5,000 to 8,000 and the maximum magnetic permeability is 500,000.
纳米晶屏蔽层33和非晶屏蔽层34具有最高磁导率性能，可使磁力线限制在磁场辐射屏蔽层靠近辐射源的一侧，进而防止扩散到屏蔽空间。纳米晶屏蔽层33是一种高频磁导率高性能吸收的屏蔽材料，屏蔽范围覆盖低频、工频、射频、高频，是目前市场上最先进的吸波材料；非晶屏蔽层34，非晶态合金作为在性能上优于传统材料的新型材料主要是利用磁旁路原理来引导场源所产生的电磁能流使它不进入空间防护区，凭借优异的性能在电磁屏蔽室、精密测量仪器、屏蔽涂料等方面得到了一定的应用，同时又具有很高的机械强度、好的韧性及耐磨性，成为使用最广泛的电磁屏蔽材料。The nanocrystalline shielding layer 33 and the amorphous shielding layer 34 have the highest magnetic permeability performance, which can limit the magnetic lines of force to the side of the magnetic field radiation shielding layer close to the radiation source, thereby preventing it from spreading to the shielded space. The nanocrystalline shielding layer 33 is a high-frequency magnetic permeability and high-performance absorption shielding material. The shielding range covers low frequency, industrial frequency, radio frequency, and high frequency. It is the most advanced wave absorbing material on the market; the amorphous shielding layer 34, amorphous alloy as a new material with superior performance to traditional materials mainly uses the magnetic bypass principle to guide the electromagnetic energy flow generated by the field source so that it does not enter the space protection zone. With its excellent performance, it has been used in electromagnetic shielding rooms, precision measuring instruments, shielding coatings, etc., and at the same time has high mechanical strength, good toughness and wear resistance, becoming the most widely used electromagnetic shielding material.

如图2所示，实施例二与实施例一的区别为：电磁辐射屏蔽层3包括若干层纳米晶屏蔽层33和若干层非晶屏蔽层34，纳米晶屏蔽层33堆叠于非晶屏蔽层34之间或粘附于非晶屏蔽层34的一侧，纳米晶屏蔽层33与非晶屏蔽层34之间通过连接层2连接。通过将可屏蔽高频磁场辐射的纳米晶屏蔽层33和可屏蔽低频磁场辐射的非晶辐射屏蔽层相结合，可有效地提高电磁辐射屏蔽层3屏蔽电磁辐射的范围，以便于实现有效地提高屏蔽电磁辐射的效率，进而降低电磁辐射对人体健康的影响。As shown in FIG2 , the difference between the second embodiment and the first embodiment is that the electromagnetic radiation shielding layer 3 includes a plurality of nanocrystalline shielding layers 33 and a plurality of amorphous shielding layers 34, the nanocrystalline shielding layers 33 are stacked between the amorphous shielding layers 34 or adhered to one side of the amorphous shielding layers 34, and the nanocrystalline shielding layers 33 and the amorphous shielding layers 34 are connected by the connecting layer 2. By combining the nanocrystalline shielding layer 33 that can shield high-frequency magnetic field radiation with the amorphous radiation shielding layer that can shield low-frequency magnetic field radiation, the range of electromagnetic radiation shielding by the electromagnetic radiation shielding layer 3 can be effectively improved, so as to effectively improve the efficiency of shielding electromagnetic radiation, thereby reducing the impact of electromagnetic radiation on human health.
实施例三：Embodiment three:
如图3所示，实施例三与实施例一的区别为：电磁辐射屏蔽层3包括纳米晶屏蔽层33，首先通过信号发生器对进行电磁辐射发射，然后将电磁辐射屏蔽层3放置于测试夹具中；如图4至图8所示，图4至图8为采用本技术领域常用的频谱分析仪对纳米晶屏蔽层33进行电磁辐射屏蔽实验检测获得的数据图表。其中，SEdb为屏蔽效能的对数表示方式(单位为dB)、SE％为屏蔽效能线性表示方式(单位为％)、P1为测试夹具中不放置电磁辐射屏蔽层3时频谱分析仪读数(单位为dBm)、以及P2为测试夹具中放置电磁辐射屏蔽层3时频谱分析仪读数(单位为dBm)。图9和图11为电磁辐射屏蔽层3受到相同辐射频率的辐射源辐射时，纳米晶屏蔽层33层数为4层和6层时的电磁辐射屏蔽效率的实验图表。As shown in FIG3 , the difference between the third embodiment and the first embodiment is that the electromagnetic radiation shielding layer 3 includes a nanocrystalline shielding layer 33, and electromagnetic radiation is first emitted by a signal generator, and then the electromagnetic radiation shielding layer 3 is placed in a test fixture; as shown in FIG4 to FIG8 , FIG4 to FIG8 are data charts obtained by using a spectrum analyzer commonly used in the technical field to perform electromagnetic radiation shielding experimental detection on the nanocrystalline shielding layer 33. Among them, SEdb is the logarithmic representation of shielding effectiveness (in dB), SE% is the linear representation of shielding effectiveness (in %), P1 is the spectrum analyzer reading when the electromagnetic radiation shielding layer 3 is not placed in the test fixture (in dBm), and P2 is the spectrum analyzer reading when the electromagnetic radiation shielding layer 3 is placed in the test fixture (in dBm). FIG9 and FIG11 are experimental charts of electromagnetic radiation shielding efficiency when the electromagnetic radiation shielding layer 3 is irradiated by a radiation source of the same radiation frequency, when the number of nanocrystalline shielding layers 33 is 4 and 6 layers.
综上所述，本实施例使用12层纳米晶屏蔽层33叠加为电磁辐射屏蔽层3，层数为12层的纳米晶屏蔽层33可使得电磁辐射屏蔽层3具有较佳的电磁辐射屏蔽效率的同时，还可使得电磁辐射屏蔽层3不至于完全屏蔽手机所发射的信号，以降低对手机使用过程的影响，还可有效地降低电磁辐射对人体的影响。根据图表可知，纳米晶屏蔽层33叠加层数对电磁辐射屏蔽效率的影响。如图18所示，在本实施例中，选择使用12层纳米晶屏蔽层33叠加为电磁辐射屏蔽层3时，电磁辐射屏蔽层3的屏蔽效果要优于坡莫合金6、Co基磁屏蔽件7、铜Cu8、铝Al9以及铁Fe10；还可看出本实施例采用12层纳米晶屏蔽层时，在相同的面积下，该厚度具有良好的优势。In summary, in this embodiment, 12 layers of nanocrystalline shielding layers 33 are used to stack as electromagnetic radiation shielding layer 3. The number of nanocrystalline shielding layers 33 is 12, which can make the electromagnetic radiation shielding layer 3 have better electromagnetic radiation shielding efficiency, and can also make the electromagnetic radiation shielding layer 3 not completely shield the signal emitted by the mobile phone, so as to reduce the impact on the use of the mobile phone, and can also effectively reduce the impact of electromagnetic radiation on the human body.
