Abstract

The invention relates to a wood coating and a preparation method thereof, belonging to the technical field of coatings. The wood coating is prepared from the following raw materials in parts by weight: 40-50 parts of polyacrylic emulsion, 0.3-0.5 part of sodium hexametaphosphate, 2-12 parts of 2,2,4-trimethyl-1,3-pentanediol isobutyrate, 1-5 parts of hydroxy fluoro-carbon resin, 0.5-2.5 parts of pentachlorodiphenyl, 0.3-5 parts of triethanolamine, 0.05-0.20 part of a defoaming agent, 15-20 parts of deionzied water, 1-1.5 parts of a thickening agent, 15-25 parts of titanium dioxide and 10-15 parts of light calcium carbonate. Aiming at the internal structural characteristics of wood, the wood coating which is applicable to coating on the surface of wood is prepared by taking polyacrylic emulsion as base resin on the basis of design of a comprehensive coating formula, and a good coating effect is achieved on the surface of wood.

Description

Technical field [0001] The present invention involves a coating and preparation method. More specifically, the invention involves a wooden coating and its preparation method, which is the field of coating technology. Background technique [0002] Wood is a structural material, which is widely used in furniture manufacturing and construction industry.In order to beautify wood products and extend the service life, it is necessary to protect it.At the same time, wood is different from other structural materials, and has a larger water content and water absorption than other materials; coatings will also penetrate inside the wood.All of this will adversely affect the effect of coating. [0003] The State Intellectual Property Office disclosed a invention patent named "Environmental -friendly Trees and Incorculus insulation coatings" in 2010.6.30, named "environmentally friendly trees and insect insulation coatings".Compared with the existing technology, the environmentally friendly t...
