Metallic surface anti-corrosion paint and preparing method thereof

Abstract

The invention discloses metallic surface anti-corrosion paint. The metallic surface anti-corrosion paint is prepared from, by weight, 60-80 parts of epoxy acrylate resin, 10-15 parts of butylated amino resin, 5-8 parts of fluorocarbon resin, 2-5 parts of methyl isobutyl ketone, 2-4 parts of cobaltous oxide, 1-2 parts of zinc phosphate, 1-2 parts of aluminum triphosphate, 5-10 parts of polymer nanometer microparticles wrapped by benzotriazole, 2-4 parts of polyacrylic ester, 1-2 parts of xylene, 2-5 parts of triethylene tetramine and 40-60 parts of industrial water. The adopted method comprises the steps that polymer nanometer materials are used for wrapping a corrosion inhibitor, and then the corrosion inhibitor is mixed into a coating. The carriers can prevent unnecessary losses of the corrosion inhibitor and prevent the corrosion inhibitor from directly damaging the coating, and certain environment stimulus responsiveness such as mechanical damage, pH changes and illumination is achieved.

Description

technical field [0001] The invention relates to a metal surface anticorrosion coating and a preparation method thereof, in particular to an anticorrosion coating suitable for metal surfaces, especially copper metal surfaces, and also discloses a preparation method of the anticorrosion coating. Background technique [0002] Corrosion of metal is a phenomenon in which metal is destroyed by chemical or electrochemical action of environmental medium. The corrosion of metals spreads all over the national economy and brings huge losses to the national economy. In industrially developed countries, the direct economic loss caused by corrosion accounts for 1% to 4% of the total output value of the national economy, the annual corroded and rusted steel accounts for about 20% of the output, and about 30% of the equipment is scrapped due to corrosion. In China, the economic loss caused by metal corrosion is as high as 30 billion yuan per year, accounting for 4% of the gross national pr...

Problems solved by technology

However, this direct incorporation method sometimes does not provide sufficient protection, and the corrosion inhibitor is in direct contact with the coating. In most cases, this system does not have the ability to release the corrosion inhibitor in response to stimuli. If When the solubility of the corrosion inhibitor in the coating is relatively high, the rapid release corrosion inhibitor will cause the coating to blister and destroy the integrity of the coating
