Problems solved by technology

[0002] The existing one-component acrylic anti-corrosion coatings are easy to construct and have a certain amount on the market. Due to the poor compactness of the acrylic resin itself, the coatings prepared with it have poor impact resistance and flexibility, and are prone to high temperature back-sticking and The shortcoming of low temperature embrittlement, which affects the long-term anti-corrosion effect of the coating

Abstract

The invention relates to a copolymer modified acrylic acid anticorrosive coating and a manufacture method thereof. The copolymer modified acrylic acid anticorrosive coating comprises thermoplastic acrylic resin, an ethylene chloride-vinyl acetate copolymer, xylene, n-butanol, n-butyl acetate, cellulose acetate butyrate, petroleum resin, rutile-type titanium dioxide, powdered steatile, mica powder, a dispersant, an adhesion improver, a scratch-resistant agent, an antifoaming agent without organosilicone, a flatting agent, an anti-settling agent and an ultraviolet light absorbent. The manufacture method comprises steps of mixing, high-speed dispersion and grinding; and during usage, a film is formed along with volatilization of the solvents. The coating has the advantages of good weatherability, long salt spray resistance, resistance to erosion of a plurality of chemical media, can be prepared into a plurality of colors and is convenient for construction; and the copolymer modified acrylic acid anticorrosive coating can be applied to anticorrosion of steel objects including ocean platform, ship deck, bridge, building, pipeline and storage tank.

Description

technical field [0001] The invention relates to a copolymer-modified acrylic anticorrosion coating which can be used for anticorrosion of steel structures and a manufacturing method thereof, and is used for anticorrosion of steel structures such as platforms, ships, bridges, buildings, pipelines and storage tanks. Background technique [0002] The existing one-component acrylic anti-corrosion coatings are easy to construct and have a certain amount on the market. Due to the poor compactness of the acrylic resin itself, the coatings prepared with it have poor impact resistance and flexibility, and are prone to high temperature back-sticking and The shortcoming of low temperature embrittlement affects the long-term anti-corrosion effect of the coating. Contents of the invention [0003] The object of the present invention is to provide a kind of adopting chlorinated ethylene vinyl acetate copolymer, cellulose acetate butyrate, petroleum resin to carry out modification and ut...
