Problems solved by technology

It can be seen that UV paint is suitable for industrialized high-efficiency production, is developing at a high speed, and has broad market application prospects. However, because UV paint is ultraviolet light penetrating radiation curing paint, the penetration of ultraviolet light in white products is obviously weakened, and it is difficult to achieve Deep curing can easily lead to paint defects such as pinholes, delamination, and yellowing by ultraviolet light

Abstract

The invention provides UV (Ultraviolet) light white finish. The UV light white finish comprises titanium white pulp, bisphenol A type epoxy acrylic resin, epoxy modified acrylic ester, UV monomer, unsaturated polyester acrylic ester, auxiliaries and auxiliaries, wherein the titanium white pulp is prepared by mixing the materials including bisphenol A type epoxy acrylic resin, titanium white pulp and dispersing agent. The UV light white finish can be used for effectively avoiding pin hole and de-lamination problems, can be used for achieving deep curing and has good yellowing resistance; a formed paint film has the excellent qualities including good leveling performance, high fullness, good hardness, high color and luster, good scratching resistance, good solution resistance and high adhesion force, and is suitable for a wood plate protecting and decorative painting system including wood floors, multi-layer floors, bamboo wood floors, consolidated composite floors, furniture and the like. Moreover, the economic benefits are good and the market prospect is broad.

Description

technical field [0001] The invention relates to a finish paint, in particular to a UV bright white finish paint. Background technique [0002] UV paint is the abbreviation of Ultraviolet Curing Paint (Ultraviolet Curing Paint), also known as photoinitiated coatings, photocured coatings, after being coated on the surface of the furniture board, the initiator is decomposed under the irradiation of ultraviolet light, generating free radicals, triggering Resin reaction, instant curing into film, is currently the most environmentally friendly paint, has the following advantages: (1) UV paint film has a three-dimensional structure, high hardness, good wear resistance, good transparency, and the product is scratch-resistant and friction-resistant. Can stand the test of time; (2) Mechanized equipment overcomes the human factors in manual operation, so that the color difference of the product is small and the quality is stable; (3) During the production process, the harmful substance...
