Problems solved by technology

However, the polyurethane glossy white topcoat applied to furniture in the market is always difficult to achieve better results in terms of fullness and flow of the paint film. In theory, such problems can be well improved by changing the filler system in the paint formulation. However, for some filler systems on the market, such as barium sulfate powder, due to its own characteristics of easy sinking and restrictions on the formulation system, it is easy to cause many disadvantages to the corresponding polyurethane bright white finish paint, such as the surface of the paint film is easy to produce convex The raised particles affect the aesthetics of the paint film, which is not conducive to the development of polyurethane bright white topcoat

Abstract

The embodiment of the invention discloses a polyurethane gloss white finish for furniture, which comprises a main agent, a curing agent and a diluent, wherein the main agent comprises synthetic fatty acid resin, n-butyl acetate, a defoaming agent, a flatting agent and white paste; the white paste comprises synthetic fatty acid resin, n-butyl acetate, a dispersing agent, titanium dioxide, and nanometer silicon potassium aluminate powder; the curing agent comprises toluene diisocyanate trimer, hexamethylene diisocyanate trimer, and n-butyl acetate; the diluent comprises n-butyl acetate, dimethylbenzene and propylene glycol monomethyl ether acetate. According to the polyurethane gloss white finish for the furniture, the nanometer silicon potassium aluminate powder is utilized, so that the sand mark covering capability and the fullness of a finish film can be improved, and the aims of reducing dark bubbles and improving a flatting effect are achieved.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a polyurethane bright white finish paint for furniture. Background technique [0002] With the improvement of material and cultural living standards, people have higher and higher requirements for the aesthetics and decorative effects of home furniture, especially the light series. However, the polyurethane glossy white topcoat applied to furniture in the market is always difficult to achieve better results in terms of fullness and flow of the paint film. In theory, such problems can be well improved by changing the filler system in the paint formulation. However, for some filler systems on the market, such as barium sulfate powder, due to its own characteristics of easy sinking and restrictions on the formulation system, it is easy to cause many disadvantages to the corresponding polyurethane bright white finish paint, such as the surface of the paint film is easy to p...
