Abstract

The invention relates to a PU (polyurethane) high-fullness anti-sinking luster white finish paint which is composed of a component A, a component B and a component C, wherein the component A is prepared from saturated polyester resin, synthetic fatty acid resin, acrylic resin, PU high-grade luster white finish slurry, dispersant, leveling agent, defoaming agent, environment-friendly solvent and the like; the component B is prepared from n-butyl acetate and curing agent; and the component C is prepared from n-butyl acetate, methylbenzene and the like. The detection and trial prove that the polyurethane white finish paint provided by the invention has the advantages of excellent yellowing resistance, strong coating adhesive force, high hardness, wear and scratch resistance, high heat resistance, favorable constructability, favorable leveling property, high fullness and excellent anti-sinking capacity; and the environment-friendly property conforms to the index in GB18581.

Description

technical field [0001] The invention relates to a bright white finish paint. Background technique [0002] At present, the PU high-fullness anti-sag bright white finish paint is an environmentally friendly coating with excellent comprehensive performance. It has the characteristics of good anti-sag, high whiteness, good fullness, and excellent yellowing resistance. It is widely used in high-end Finish coating of suite furniture and high-end cabinet furniture. After the construction of similar products on the market, the common disadvantages are slow drying speed, poor fullness, general adhesion, and general yellowing resistance. Contents of the invention [0003] The purpose of the present invention is to provide a PU high-fullness anti-sag bright white finish, which forms a layer of high-fullness, excellent anti-sag, high whiteness, and yellowing resistance on the surface of wooden furniture or suite furniture. Improved, environmentally friendly surface coatings. [00...
