Preparation method of waterproof anticorrosion vehicle paint

Abstract

The invention provides a preparation method of a waterproof anticorrosion vehicle paint. The waterproof anticorrosion vehicle paint comprises following raw materials in parts by weight: 80 to 100 parts of polyvinyl alcohol, 45 to 60 parts of ethylene-vinyl acetate copolymerization emulsion, 10 to 15 parts of toluene diisocynate, 12 to 18 parts of vinyl triethoxysilane, 20 to 30 parts of dimethyl silicone oil, 10 to 12 parts of acrylic emulsion, 10 to 15 parts of epoxy resin, 1 to 2 parts of an active crosslinking agent, 3 to 6 parts of a stabilizing agent, 1 to 2 parts of an antioxidant, 0.5 to 0.8 part of an antirust agent, and some parts of deionized water. The paint is painted on the surface of the structural parts on the surface of a vehicle shell to form a coating having waterproof, anticorrosion and flame retardant functions. Thus water and corrosive substances will not enter the interior of the structural parts, layering of materials is avoided, the structural parts are protected, moreover, the paint also has a fire resistant effect, and the service life of the structural parts is prolonged.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a preparation method of a waterproof and anti-corrosion vehicle coating. Background technique [0002] With the rapid development of modern industry, people have higher and higher requirements for waterproof and anti-corrosion measures for automobile shells. At present, general automobile shells do not have good waterproof and anti-corrosion measures. To meet modern people's requirements for new building materials, people are paying more and more attention to the development of a coating that can improve the anti-corrosion performance of profiles, and the coating of automobile shells is painted with a primer for anti-rust to ensure weather resistance It consists of three layers: a top coat for the purpose of sex and beauty and a mid-coat for improving the adhesion between the base coat and the top coat. The coating life is affected by the coating material and the use environment...

[0002] With the rapid development of modern industry, people have higher and higher requirements for waterproof and anti-corrosion measures for automobile shells. At present, general automobile shells do not have good waterproof and anti-corrosion measures. To meet modern people's requirements for new building materials, people are paying more and more attention to the development of a coating that can improve the anti-corrosion performance of profiles, and the coating of automobile shells is painted with a primer for anti-rust to ensure weather resistance It consists of three layers: a top coat for the purpose of sex and beauty and a mid-coat for improving the adhesion between the base coat and the top coat. The coating life is affected by the coating material and the use environment. The impact is very great. The coating prepared according to the current technology has poor waterproof and anti-corrosion properties. As a result, the protective effect of the coating on the shell will drop sharply, which will affect the overall service life of the car.
