Abstract

The invention discloses UV matte white finish paint on a melamine board and preparation of the UV matte white finish paint. The UV matte white finish paint is prepared from modified UV adhesive force resin, modified UV acrylic resin, modified epoxy acrylic resin, dipropylene glycol diacrylate (DPGDA), hydroxyethyl methylacrylate (HEMA), an acrylic copolymer dispersing agent, a rheological additive, a base material wetting agent, a non-silicon defoaming agent, a fluorocarbon modified polymer leveling agent, a 184 photoinitiator, a GR-TPO photoinitiator and fumed silica. A component A is composed of imported rutile titanium dioxide, matting powder, a cellulose acetate butyrate solution (20% cellulose acetate butyrate and 80% butyl acetate) and butyl acetate, and a component B is composed of butyl acetate, butyl acetate and propylene glycol methyl ether acetate. During construction, the component A and the component B are uniformly mixed in proportion. Detection and trial prove that in the construction process, the UV matte white finish is low in odor, good in paint film dryness, good in whiteness, high in fullness, uniform in gloss, fine and smooth in hand feeling, high in hardness, good in water resistance and chemical resistance and good in yellowing resistance. The paint is suitable for coating melamine boards in furniture.

Description

technical field [0001] The invention relates to the technical field of wood coating manufacturing, in particular to a UV matte white finish on a melamine board and a preparation method thereof. Background technique [0002] The conventional furniture boards with UV white paint on melamine boards on the market now need to spray a special primer for melamine adhesion first, then spray UV sanding primer, and then spray UV after sanding. White topcoat, the production process is relatively complicated, the coating efficiency is low, and the overall cost is high. The product of the present invention can be directly sprayed on the melamine board after being polished, and can be molded at one time, which can obviously improve the coating efficiency and reduce the overall cost of coating. [0003] The present invention mainly selects excellent modified UV adhesion resin and modified UV acrylic resin, which can solve the problem of adhesion on the melamine board. At the same time, ad...
