Abstract

The invention discloses a double-component polyurethane white high-gloss woodware paint, and a preparation method and application thereof. The double-component polyurethane white high-gloss woodware paint comprises a main paint, a curing agent and a diluter, wherein the main paint, the curing agent and the diluter are evenly mixed according to a mass ratio of 1:1:(0.2-0.5) prior to use; the main paint comprises alkyd resin, rutile titanium dioxide, dispersant, defoaming agent, leveling agent and a high-boiling-point mixed environment-friendly solvent; the curing agent comprises polyisocyanate resin A, polyisocyanate resin B, a high-boiling-point mixed environment-friendly solvent and water absorbent; and the diluter is composed of one or more than two high-boiling-point mixed environment-friendly organic solvents. The double-component polyurethane white high-gloss woodware paint can be polished after being dried for 16 hours, and the hardness can meet the requirements for polishing, so that the production cycle of polished white high-gloss furniture is greatly shortened, thereby improving the production efficiency, saving a large amount of financial resources and having high economic value.
