Abstract

The invention discloses ultraviolet (UV) laser roller coating woodware matt finish. The UV laser roller coating woodware matt finish consists of the following components in percentage by weight: 30-57 percent of resin, 29-40 percent of monomer, 8-20 percent of fumed silica, 4-7 percent of photoinitiator and 1.8-4.8 percent of other aids, wherein the resin is a mixture of an epoxy acrylate resin and aliphatic modified polyurethane acrylate. According to the UV laser roller coating woodware matt finish, no construction trace is left and an excellent mirror surface effect can be achieved. Moreover, the UV laser roller coating woodware matt finish is high in adhesion force, high in fullness, high in brightness and environment-friendly and has good decorative and protective effects, the product quality and production efficiency can be greatly improved, and emission of an organic solvent can be reduced.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a UV laser roller-coated wooden matt finish. Background technique [0002] UV paint is a light-curing paint. It is currently a widely used furniture paint. Its main features are: after strong ultraviolet light curing treatment, the color is stable and always new. Therefore, it is widely used in cabinet furniture, etc., which can improve the anti-collapse, hardness, and reduce costs. However, the effect of UV roller coating using ordinary rubber rollers always has roller marks, so the conventional method is UV primer. Spray PU surface or NC surface on it. In this way, the number of processes increases, the working hours are lengthened, and the overall efficiency of painting is reduced. [0003] Contents of the invention [0004] The object of the present invention is to aim at the deficiencies in the prior art, provide a kind of UV laser roller coating woodware matt topcoat ...
