Detailed Description
Example 1
Referring to fig. 1, an embodiment of the present application provides a full-automatic uv curing printing method, including the following steps.
And step S1, collecting the color information of the ultraviolet curing ink layer coated on the printing stock.
In the printing process, the thickness of the ultraviolet curing ink is too small, such as 1um, and the printing layer obtained after curing is easy to fall off. And when the thickness of ultraviolet curing printing ink is too big, for example 50um etc. because its thickness is too big, in the in-process of solidification, the printing ink layer inboard that is close to the stock is difficult for drying, leads to printing ink layer solidification difficulty. Therefore, the thickness of the printing ink on the printing stock is any value between 10-20 um, so that the printing ink is convenient to dry and cure, and the cured layer is not easy to fall off.
The ultraviolet curing printing ink provided by the embodiment of the application comprises the following components in parts by weight: 10-30 parts of a mixture of acrylate and vinyl chloride-vinyl acetate copolymer; 20-50 parts of electrodeless persalt; 1-2 parts of an ultraviolet initiator; 1-6 parts of a color agent; 5-10 parts of a cosolvent; 5-10 parts of a lubricant; 0.5-1 part of defoaming agent; 0.5-1 part of a dispersant; 0.5-1 part of thickening agent.
Example 1: the ultraviolet curing printing ink comprises the following components in parts by weight: 20 parts of a mixture of acrylate and vinyl chloride-vinyl acetate copolymer; 35 parts of non-polar persalt; 1.5 parts of ultraviolet initiator; 3.5 parts of a color agent; cosolvent 7.5 weight portions; 7.5 parts of a lubricant; 0.8 part of defoaming agent; 0.8 part of dispersant; 0.8 part of thickening agent.
Example 2: the ultraviolet curing printing ink comprises the following components in parts by weight: 10 parts of a mixture of acrylate and vinyl chloride-vinyl acetate copolymer; 20 parts of non-polar persalt; 1 part of ultraviolet initiator; 1 part of color agent; 5 parts of cosolvent; 5 parts of a lubricant; 0.5 part of defoaming agent; 0.5 part of dispersant; 0.5 part of thickening agent.
Example 3: the ultraviolet curing printing ink comprises the following components in parts by weight: 30 parts of a mixture of acrylate and vinyl chloride-vinyl acetate copolymer; 50 parts of electrodeless persalt; 2 parts of ultraviolet initiator; 6 parts of a color agent; 10 parts of cosolvent; 10 parts of a lubricant; 1 part of defoaming agent; 1 part of dispersant; 1 part of thickening agent.
And step S2, comparing the color information with a preset ultraviolet lamp parameter table, and determining working parameters of the ultraviolet lamp according to the comparison result, wherein the working parameters comprise illumination wavelength and illumination time.
In one possible implementation, the ultraviolet lamp parameter table includes a plurality of color information, and each color of ink corresponds to a specific operating parameter, which includes the illumination wavelength and the illumination time. For example, for black ink, the illumination wavelength is 400nm, and the illumination time is 3-5S, so that the black ink can be rapidly and completely cured. For yellow ink, the illumination wavelength is 360nm, and the illumination time is 2-3 seconds, so that the yellow ink is rapidly cured, and the working efficiency is improved.
In another possible implementation, the ultraviolet lamp parameter table includes a plurality of color information, and a first operating parameter and a second operating parameter corresponding to each color information. And adjusting the actual illumination wavelength and the actual illumination time of the ultraviolet lamp according to the first working parameter, and carrying out primary curing on the ink layer on the printing stock. And adjusting the actual illumination wavelength and the actual illumination time of the ultraviolet lamp according to the second working parameter, and strengthening and curing the ink layer on the printing stock. For example, the first operating parameter of the ultraviolet lamp corresponding to the yellow ink is 365nm and the illumination time is 1-2S, and the second operating parameter is 360nm and the illumination time is 1-2S.
It should be noted that the process parameters for each color ink can be determined based on specific experiments and experience, and the parameters provided herein are merely exemplary.
And step S3, adjusting the actual illumination wavelength and the actual illumination time of the ultraviolet lamp according to the illumination wavelength and the illumination time, and curing the ink layer on the printing stock to obtain the printing layer.
Taking the two-stage curing for yellow ink as an example, the specific curing process is as follows: and carrying out primary curing on the ink layer on the printing stock by adopting first working parameters, namely the wavelength of an ultraviolet lamp is 365nm and the illumination time is 1-2S. And (3) reinforcing and curing the primarily cured printing ink layer by adopting second working parameters, namely the wavelength of the ultraviolet lamp is 360nm, and the illumination time is 1-2S, so as to obtain the printing layer. It is worth explaining that the ink layer after twice curing has the characteristics of thorough curing, smooth surface and fine hand feeling.
And step S4, turning on an infrared lamp, and drying the printing layer.
And step S5, turning on a glazing ultraviolet lamp, and carrying out ultraviolet glazing treatment on the dried printing layer.
Each ultraviolet lamp has a service life, and the service lives of different ultraviolet lamps are different from 1000h to 8000 h. If the total service time of the ultraviolet lamp exceeds the service life of the ultraviolet lamp, the illumination of the ultraviolet lamp is changed, so that the ink layer cannot be completely cured, or the required curing time is longer, and the production efficiency is reduced. Thus, the present application performs the steps shown in fig. 2 after each use of the uv lamp to avoid the above-described problems.
S6, recording the single actual illumination time of the ultraviolet lamp, and determining the total illumination time of the ultraviolet lamp according to the single actual illumination time.
S7, judging whether the total illumination time exceeds the illumination time threshold value, if so, sending an ultraviolet lamp replacement instruction.
It should be noted that the steps S6 and S7 may be set between the steps S3 and S4, or may be set after the step S6, and the present application limits this in parallel.
