Abstract

The invention discloses high-performance acrylic ester modified water-based polyurethane emulsion paint. The paint is prepared from, by weight, 50-100 parts of acrylic ester modified polyurethane emulsion, 5-20 parts of water-based alkyd resin, 5-15 parts of nanometer silica sol, 15-30 parts of pigment filler, 5-10 parts of propanediol, 5-10 parts of n-caprylic alcohol, 2-5 parts of hexamethyl-disilazane, 5-10 parts of cellulose nanocrystalline, 0.5-3 parts of polyacrylamide, 5-15 parts of coalescing agents, 0.5-3 parts of antifoaming agents, 0.5-1.5 parts of sodium hexametaphosphate, 1-3 parts of benzotriazole, 1.5-3 parts of tributyl phosphate, 0.5-1.5 parts of triphenyl phosphate, 1-3 parts of hexakis methoxymethyl melamine resin, 0.5-2 parts of palm oil and 50-70 parts of deionized water. The high-performance acrylic ester modified water-based polyurethane emulsion paint is good in water resistance and weather resistance and high in strength.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-performance acrylate-modified water-based polyurethane latex paint. Background technique [0002] With the daily increase in the price of chemical raw materials, the price of solvent-based coatings has become the key to restricting its wide application. Latex paint is a water-dispersible paint. It is based on synthetic resin emulsion, and the filler is refined by adding various additives after grinding and dispersing. Compared with solvent-based paints, water-based latex paints use water as a solvent, which can save a lot of resources, eliminate the risk of fire during construction, reduce air pollution, have good adaptability to the surface of materials, and have strong coating adhesion. The coating tools can be cleaned with water, greatly reducing the consumption of cleaning solvents. However, the water resistance, weather resistance and mechanical properties of latex...
