Abstract

The invention discloses a white ultraviolet curing finishing coat which consists of the following components by weight percent: 50-70 percent of resin, 23-40 percent of an acrylate compound monomer, 4.5-9.5 percent of a photo-initiator and 0.3-3.0 percent of an aid, wherein the resin is a mixture consisting of epoxy acrylate and urethane acrylate; the acrylate compound monomer is one or a mixture of two of hydroxyethyl methylacrylate, tripropylene glycol diacrylate, 1,6-hexanediol diacrylate, dipropylene glycol diacrylate and trimethylolpropane triacrylate. The white ultraviolet curing finishing coat can be sprayed instead of the conventional solvent based coating, and has the advantages of high curing speed, high production efficiency, lower plate production cost, energy saving, carbon reduction and the like.

Description

technical field [0001] The invention relates to an ultraviolet-curable white topcoat which can be used for coating floors, furniture, decorative panels and the like. Background technique [0002] At present, the high-gloss processing technology of existing furniture and decorative panels needs to go through the processes of spraying, drying, and polishing; the spraying generally uses traditional solvent-based polyurethane coatings and nitro-based coatings, and the release of organic solvents in these coatings will pollute the environment. And its drying time is longer, needs to operate and wait through the longer time, has caused problems such as resource waste. The above-mentioned processes and factors have caused a lot of resource waste and pollution, greatly increased the manufacturing cost of the enterprise and seriously restricted the production capacity of the enterprise. [0003] Later, the development of UV-curable white topcoat greatly shortened the production time...
