Abstract

The invention discloses a composite epoxy anticorrosion coating and a preparation method thereof. The composite epoxy anticorrosion coating is composed of two components A and B according to the ratio of A:B=2:1. Group A includes the following components: organosilicon Modified epoxy resin, pigment, filler, plasticizer, dispersant, film-forming aid and defoamer; component B includes the following components: polyphenylene ether resin powder, styrene-butadiene rubber, toluene, plasticizer, Coupling agent, auxiliary material and flame retardant; Prepare by mixing components A and B separately, and then spray B on A to form a composite epoxy anti-corrosion coating. The composite epoxy anti-corrosion coating is made of two-component composite with excellent resistance High temperature and wear resistance, it also has good adhesion and low shrinkage, and has good corrosion resistance and penetration resistance to water, medium acid, alkali and other solvents. At the same time, the composite epoxy anti-corrosion coating The composite epoxy anticorrosion paint has excellent flexibility and paint construction performance, and the preparation method of the composite epoxy anticorrosion paint is simple and low in cost.

Description

technical field [0001] The invention belongs to the technical field of anticorrosion, and relates to an anticorrosion paint and a preparation method thereof, in particular to a composite epoxy anticorrosion paint and a preparation method thereof. Background technique [0002] Corrosion is the degradation and destruction of metal materials under natural conditions or working conditions due to chemical or electrochemical interactions with the surrounding medium. This phenomenon is called corrosion. Corrosion problems pervade various sectors and industries, and have caused great harm to national economic development, human life and social environment. According to statistics, the annual loss caused by corrosion in the world is as high as 1 trillion U.S. dollars, and the annual economic loss caused by corrosion damage in various countries accounts for about 2%-4% of the total national economic output value of the year. rather different. According to the "China Corrosion Invest...
