Abstract
The invention relates to low-carbon paint, the formula proportion is as follows by weigh parts: 90-95 parts of bisphenol A epoxy resin, 3-5 parts of ureaformaldehyde, 3-5 parts of propanediol methyl ether amyl acetate, 2-3 parts of nanometer aluminum oxide, 0.3-0.5 part of polyorganosiloxane antifoaming agent, and 0.1-0.2 percent of polyether modified siloxane solvent; the formula proportion is formulated; the mixing solution : polyether amine hardeners=100:30; the paint has good chemical resistance and luster, super low VOC, high elasticity and chemical resistance, and is environment-protection and has low toxicity; in the invention, the advantages of the epoxy resin and aldehyde resin are fully utilized, a paint film with elasticity is formed by utilizing the reaction of the bisphenol A epoxy resin and the polyether amine, the luster performance of the aldehyde resin is fully utilized, and the paint film has high elasticity; in addition, 3-5 percent of environmental protection level solvent propanediol methyl ether amyl acetate is added in the formula, the VOC content is reduced to 50mg and is far less than the national standard-600mg, so as to realize low-carbon environment protection really.
Description
technical field [0001] The invention relates to a surface wood varnish used in home decoration paint and furniture production, in particular to a preparation method of the surface paint. Background technique [0002] At present, wood coatings used in household and furniture production are basically solvent-based coatings, which contain a large amount of volatile organic compounds VOC, pollute the environment, damage painters, and affect the health of consumers. The oil-based wood paints currently on the market have high VOC content, high free TDI content, strong odor, low solid content, low abrasion resistance, and poor impact resistance. Contents of the invention [0003] The purpose of the present invention is to provide a low-carbon paint, which can effectively improve the elasticity, water resistance, and chemical resistance of oil-based wood paint, improve the hardness, fullness, feel, and wear resistance of the paint film and realize ultra-low carbon paint. .
