Abstract

The invention relates to bright white paint for wooden ware and preparation as well as application of the bright white paint. The white paint comprises a component A, a component B and a diluting component C, wherein the component A and the component B are stored separately, and are mixed for reaction and then diluted when being used; the weight ratio of the component A to the component B to the diluting component C is 1: 0.6-0.8: 0.4-0.6. The bright white paint for wooden ware, disclosed by the invention, has the advantages of strong covering power and adhesive force, high hardness, high glossiness, good high-temperature resistance, good water resistance, good chemical resistance, and good light-protection and color-protection performances; and the bright white paint for wooden ware has good leveling performances, and is easy to spray during the construction, and has excellent effects especially in the aspects of yellow stain resistance and weather resistance.

Description

【Technical field】 [0001] The invention relates to a bright white finish paint for woodware and its preparation and application, belonging to the technical field of paint manufacturing industry. 【Background technique】 [0002] PU bright white topcoat is a kind of wood coating with excellent comprehensive performance.
