Description
Technical Field
The technical scheme is the application of a material technology in the technical field of decorative plates, and particularly relates to a 3D flat printing decorative plate based on an electron beam curing technology.
Background
In the prior art, the manufacture of decorative boards such as density boards, stone-plastic boards, glass-magnesium boards and the like can be implemented by adopting a flat printing process. The principle of the technology is that firstly, the ground color (white is used mostly) is processed on the substrate, then UV printing ink is sprayed on the ground color layer by a flat printer to form a pattern, and UV is adopted for curing. The process has the advantages that the processing process is simple, the manufactured plate does not need ways of pasting a color film and the like, and glue and hot pressing/cold pressing processes are not used; the printing pattern is flexible, and the pattern is edited in computer software and printed by a flat-panel printer. But there are disadvantages mainly from the UV curing process. While UV curing has replaced the more defective thermal curing in the art, however:
1. the UV curing needs to adopt a photoinitiator with high price, and the cost of printing ink and the like is high; the photoinitiator and the photolysis product are migrated and volatilized, and peculiar smell is generated; insufficient aging resistance of ink and the like; it cannot be used in food and medicine fields.
2. In particular, in the case of colored coatings such as inks and paints, UV curing is difficult to transmit due to the absorption of light by pigments, and a common method for solving this problem is to increase the amount of photoinitiator.
In conclusion, the difficult problems encountered with conventional UV curing are the off-flavors caused by the photoinitiators and the insufficient resistance of the inks to ageing.

the primer layer is made of a UV primer; the pattern layer is made of spray painting color UV ink; the wear-resistant layer is made of UV wear-resistant paint; the texture layer is made of spray-painted transparent UV ink; the scratch-resistant layer is made of transparent coating cured by electron beam radiation;
the manufacturing steps of the decorative plate comprise:
1) uniformly coating the UV primer on the surface of the substrate, and performing radiation curing by using ultraviolet rays with corresponding energy according to the unit dosage of the UV primer;
2) printing the color of a design drawing on the surface of the primer layer by using an ink-jet flat printer and curing to prepare a pattern layer;
3) coating the UV wear-resistant coating on the surface of the pattern layer, and performing radiation curing by using ultraviolet rays with corresponding energy according to the unit dosage of the UV wear-resistant coating;
4) printing design pattern textures on the surface of the wear-resistant layer by using an ink-jet flat printer, and curing to obtain a texture layer;
5) uniformly coating the transparent coating cured by electron beam radiation on the surface of the texture layer, wherein the average dosage of the transparent coating is as follows: 10-14 g/square meter; then, curing by electron beam radiation, wherein the energy of the electron beam is adjusted to 30-40 kgy;
and curing to obtain the decorative board product.
Further: the primer layer is prepared from 20-24 g/square meter of UV primer, and is irradiated and cured by a mercury lamp light source ultraviolet lamp, and the light energy is adjusted to 190-280 mJ; the wear-resistant layer is made of UV wear-resistant paint according to the dosage of 64-96 g/square meter, and is irradiated and cured by a mercury lamp light source ultraviolet lamp, and the light energy is adjusted to 240-280 mJ.
Further: in the steps 1), 3) and 5), the coating mode is roll coating or curtain coating.
Further: the base plate is a density board (furniture veneer), a stone plastic board (floor) and a glass magnesium board (wallboard), and at the moment, the decorative board is used for the floor, the wallboard or the furniture veneer.
Further: the substrate is a PP film, a PET film or a PVC film with the thickness of 0.1-1.0 mm, and the substrate is used as a plate decoration protective film. When the protective film is used as a protective film, the bottom surface of a PP film, a PET film or a PVC film is coated with glue and pasted on site, or a non-dry glue layer is pre-coated during production.
Further: in the steps 1) to 4), the production environment temperature needs to be controlled to be 15-25 ℃.
The layered structure of the decorative plate is the same as that of the decorative plate in the prior art, and the differences mainly comprise the coating used by each functional layer and the unit dosage. The function and performance of the decorative plate are better and the decorative plate is more convenient to produce by combining the processing technology.
In the technical scheme, the penetration depth of the electron beam is large; the electron beam causes chemical bonding (e.g., grafting) between the coating materials of the scratch-resistant layer and between the coating materials of the adjacent layers, thereby improving the adhesion of the scratch-resistant layer. The solidified scratch-resistant layer can completely seal the UV solidified coating, so that peculiar smell brought by the photoinitiator can not be emitted into the air. The scratch-resistant layer has sufficient protection on the coating below the scratch-resistant layer, the problem of insufficient aging resistance of UV curing ink is solved, and meanwhile, the UV ink with a small content of photoinitiator can be selected to manufacture the pattern layer.
