Description

Wire heating element using PE PET fabric and its manufacturing method {Plane heater of wiring type make use of polyethylene pet and a manufacturing method of it}

The present invention relates to a heating element and a method of manufacturing the same, and more particularly, to a heating element that provides a semi-permanent and stable heating function excellent in waterproof and insulation effect with a heat-adhesive adhesive coating using a PE plastic fabric and a method for manufacturing the same.

Ordinary planar heating elements that generate electricity by heating are not only sanitary because they do not pollute the air, but their mattresses, pads, bed mattresses, thermal blankets, blankets, apartments, or generals require heat generation because they are easy to control and have no noise. It is widely used for residential heating devices such as houses. In addition, the heating of commercial buildings such as offices and shops, industrial heating devices such as workshops, warehouses, barracks, and various industrial heating devices, agricultural equipment such as vinyl houses and agricultural product drying systems, and melting snow or preventing freezing of roads and parking lots In addition to various freeze protection devices that can be used, it is also used for leisure, cold protection, home appliances, anti-fog of mirrors and glass, health supplement, livestock.

Conventional planar heating element is made by applying carbon black to woven fabric, which is manufactured by mixing various chemicals and applying it to woven fabric and drying, which not only makes the manufacturing process complicated but the thickness of the coated carbon black is not constant and carbon The distribution of particles was uneven, so that the entire surface of the heating element did not generate heat at a uniform temperature.

In addition, when the planar heating element is folded and unfolded, the structure of the carbon black of the folded portion is easily destroyed, and when the planar heating element is used, there is a problem that the resistance value is changed by the change in the outside air temperature and the change in the self-heating temperature.

Such a conventional carbon coated planar heating element may cause a spark when a hole is formed, which may lead to a fire, and the thermal efficiency has deteriorated over time, which has been the biggest obstacle to the popularization of the planar heating element.

Therefore, the object of the present invention was devised in view of the above-mentioned point, in the production of the heating element to provide a semi-permanent and stable heating function by reinforcing the automation and durability of the manufacturing process by the heating yarn adhesive coating using a PE plastic fabric and mass production The present invention provides a wire heating element using the easy PE pad fabric and a method of manufacturing the same.

In order to achieve the above object, the wire heating element using the PE pad fabric of the present invention is a heating element, which generates heat in a zigzag form at regular intervals between the polyethylene (PE) pad fabric and the PE pad fabric upper and lower legs. Yarns, and copper tapes disposed on both ends of the PE pad fabric separated by a predetermined width from the heat generating yarns to form electrodes, wherein the heat generating yarns and copper tapes are electrically connected at predetermined intervals to form terminal portions. It is characterized in that the upper and lower PE pad fabric is compressed and integrated with each other.

Method for producing a heating element using a PE pad fabric for achieving the object of the present invention, in the method for producing a heating element using a polyethylene (PE) pad fabric, (1) the heating yarn in a zigzag shape on the base of the PE pad fabric. And (2) pressing and fixing a corner portion through a heating device at the same time as the heating yarn is excreted, and (3) disposing copper tapes on both sides of the lower surface of the PE pad fabric to apply electrodes for power. Forming step, and (4) covering the PE pad fabric upper surface on the bottom of the PE pad fabric in which the heating yarn and the electrode are disposed, and adhesively coating each other through a heated roller to make a finished product.

The wire heating element and the manufacturing method using the PE plastic fabric of the present invention is excellent in waterproof and insulation effect by the use of the upper and lower PE plastic fabric, semi-permanent and durable, very low damage (damage) It is easy to use and to carry out construction, and there is almost no temperature change, and the manufacturing process can be automated, so it is easy to mass production and easy to handle, so it can be applied to various fields such as heating panels.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view schematically showing the configuration of a heating element using a PE plastic fabric according to the present invention.

Referring to FIG. 1, a heat generating yarn 20 is disposed in a zigzag form on a lower surface 10A of a polyethylene (PE) plastic fabric 10A, 10B, which is an adhesive coating, and at both ends, electrode tapes 30A, 30B) is excreted and heat-compressed by laminating the upper limb 10B of PE plastic fabric thereon to constitute a heating element. Here, the heat generating yarn 20, which is arranged in multiple rows at predetermined intervals, intersects the electrode tapes 30A and 30B to enable energization. The electrode tapes 30A and 30B are further provided with terminals 40A and 40B for supplying power by connecting power lines (+,-).

In the present embodiment, the heat generating yarn 20 used is developed by the present applicant, and mixed non-ferrous metal materials such as chromium, nickel and carbon in stainless steel in a predetermined ratio, and pulled into a thread in a state in which it is dissolved at 1,400 ° C. or higher. It is designed to have superior flexibility, conductivity, and resistance compared to exothermic yarns made of conventional carbon fiber yarns, and excellent antibacterial and deodorizing functions due to the generation of far-infrared rays and anions.

In addition, the fabric used in the present embodiment is a pad made of polyethylene (PE) used in various container packaging films, fibers, pipes, packing, paints and the like. PE fabric is coated with adhesive resin for perfect waterproof and insulation effect. Total thickness is about 0.3mm and upper and lower thicknesses are different. The upper limb is about 0.15 mm, and the lower limb is adhesive coated about 0.10 mm.

A manufacturing process for the heating element of FIG. 1 having such a structure will be described in detail with reference to FIG. 2.

Therefore, both ends of the heat generating yarn 20 to be disposed on the lower surface of the PE plastic fabric 10A to facilitate the excretion of the heat generating yarn 20. Then, following the excretion process of the heat generating yarn 20 from both sides, a copper tape mounted on the holder 150 is installed to form the electrodes 30A and 30B. At this time, when the heat generating yarn 20 is disposed in a zigzag on the PE pad fabric base 10A, electrical contact with the copper tape is made at regular intervals. Then, the PE plastic fabric fabric 160 is rotated to release the wound PE plastic fabric to cover the upper surface of the PE plastic fabric fabric 10A on which the heating yarn 20 and the electrodes 30A and 30B are formed. Subsequently, the upper and lower surfaces 10A and 10B of the PE pad fabric are pressed through the heated Laura 170 to seal the internal components to complete the heating element as shown in FIG. 3. The finished product is wound along the take-up roll 180.
