The chlorosulfonated polyethylene anti-corrosion coating disclosed by the invention has good atmosphere aging resistance, corrosion resistance and electromagnetic shielding property.

Description

technical field [0001] The invention relates to the technical field, in particular to a chlorosulfonated polyethylene anticorrosion coating added with nano ferrite graphene composite material. Background technique [0002] Corrosion and anticorrosion are prominent problems in chemical industry, light industry, metallurgy, electric power, textile, printing and dyeing, shipbuilding, construction and other industries. Corrosion causes huge losses every year, so anti-corrosion work is particularly important. Chlorosulfonated polyethylene anti-corrosion coatings are widely used for their excellent corrosion resistance, especially excellent flexibility, and the price is not high. Once favored by the industry. With the rapid development of modern industrial level, higher and stricter ability to withstand environmental corrosion has been put forward for anti-corrosion coatings. The anti-corrosion performance of chlorosulfonated polyethylene coatings produced by traditional formula...

Problems solved by technology

Due to the addition of water-based epoxy resin, the adhesion of the coating is improved while the anti-corrosion performance is reduced, and the comprehensive performance of chlorosulfonated polyethylene cannot be effectively improved. It is necessary to further improve the water-based chlorosulfonated polyethylene coating. To meet the needs of industry development
