Abstract

The invention discloses environment-friendly type bright white finish with high solid content and high fullness for woodware. The environment-friendly type bright white finish comprises the following components in parts by weight: components A: 15-25 parts of bisphenol A epoxy resin, 25-35 parts of hydrogenated bisphenol A epoxy resin, 8-12 parts of active flux butyl glycidyl ether, 5-10 parts of titanium dioxide, 25-35 parts of inorganic fillers, 0.5-1 part of an anti-settling agent, 0.5-1 part of a dispersing agent, 0.1-0.5 part of an antifoaming agent, 0.6-1.5 parts of a flatting agent, 1-2 parts of anti-yellowing auxiliaries; component B: modified alicyclic amine curing agent; component C: ketones solvent, wherein the weight ratio of the components A:component B:component C is 100:(30-35):(5-8). The environment-friendly type bright white finish with high solid content and high fullness for woodware, disclosed by the invention, saves labor cost and shortens working hours; moreover, construction solid content (greater than 90%) is far higher than that (50%-55%) of the common polyurethane bright white finish. Moreover, requirements of paint with ultrahigh solid content are achieved, and pollution to environment caused by volatilization of an organic solvent is reduced.

Description

technical field [0001] The invention belongs to the field of paints, and in particular relates to a high-solid-content, high-volume, environment-friendly bright white finish for woodware. Background technique [0002] For a long time, in the furniture market, polyurethane bright white finish occupies a large market share. The painting process of general furniture factories is to spray the PU white topcoat after the PE white primer is dried and polished. Through market research, it is found that the traditional high-fullness PU bright white finish paint has low solid content (generally between 50% and 55%), and has high requirements for the treatment of PE substrates. At least 600 mesh sandpaper can barely cover the sand. marks, still unsatisfactory. Contents of the invention [0003] The purpose of the present invention is to provide a high-solid-content, high-volume, environmentally-friendly bright white topcoat for wood, which solves the problem of low solid content in...
