Abstract

The invention discloses a UV-cured white curtaining paint and a preparation method thereof. The UV-cured white curtaining paint comprises the following raw materials by mass percentage: 30 to 50 percent of a UV cured oligomer, 20 to 40 percent of acrylate monomer, 4 to 8 percent of a photoinitiator, 0 to 10 percent of matting agent, 1 to 2 percent of additives and 5 to 15 percent of titanium dioxide, wherein the UV cured oligomer is one or mixture of several oligomers of aliphatic urethane acrylate, amino polyester acrylate and polyester acrylate; the photoinitiator is 1- hydroxy-cyclohexyl-phenyl-ketone. The method comprises the following steps: mixing of the oligomer and part of the acrylate monomer for resolving, stirring, adding of the additives, stirring, adding of the matting agent and the titanium dioxide, high-speed stirring, adding of the rest monomer after a dispersion fineness is reached, low-speed stirring for 10 to 20 minutes, vacuumizing for 30 min at 45 DEG C, and filtering to obtain the UV-cured white curtaining paint. The UV-cured white curtaining paint is high in adhesive attraction, excellent in hiding power, good in deep curing, and high in fullness, thereby being suitable for curtaining construction.

Description

technical field [0001] The invention belongs to the field of preparation of UV (ultraviolet light curing) coatings, and particularly relates to a method for preparing colored (white) ultraviolet light curing coatings in a flow coating construction mode. Background technique [0002] UV-curable coatings are pigmented paints developed on the basis of UV-cured. Since deep-layer UV curing has always been a difficult problem in the industry, the current UV-cured pigmented paints basically stay at low coating volumes. Roll coating, because increasing the amount of coating increases the hiding power, but it cannot be cured deeply, and this effect cannot be achieved. In particular, it is not easy to achieve high-fullness flow-coated colored paints. It is a very technical and promising project to develop flow-coated colored paints. At present, in colored coating, there is a great demand for white, especially for kitchen and bathroom, wardrobe, office furniture and other coatings wit...
