Chlorosulfonated ethylene composite anticorrosive paint with organic montmorillonite modified zinc powder

Abstract

The invention discloses chlorosulfonated ethylene composite anticorrosive paint with organic montmorillonite modified zinc powder. The composite anticorrosive paint is prepared from the following raw materials in parts by weight: 60 to 65 parts of chlorosulfonated polyethylene latex, 35 to 40 parts of neoprene latex, 7 to 8 parts of polyoxyethylene aliphatic alcohol ether, a proper amount of deionized water, 2.5 to 3 parts of silane coupling agents KH560, 2 to 3 parts of lanthanum oxide, 1.5 to 2 parts of cerous oxide, a proper amount of nitric acid solution with the concentration being 65 weight percent, ammonium bicarbonate solution with the concentration being 50 weight percent, 10 to 12 parts of rutile titanium dioxide, 1 to 1.5 parts of methyl acrylate, 0.8 to 1 part of sodium hexametaphosphate, 6 to 7 parts of flake zinc powder, 3 to 4 parts of organic montmorillonite, 8 to 9.5 parts of silica sol and 1 to 1.2 parts of potassium hydroxide. The prepared paint has the advantages that the mechanical property is excellent; the advantages of good surface adhesion force on the surface of metal, high covering capability, high floating capability and high shielding capability are prominent; the anticorrosion performance is excellent; the process is simple; the industrial control is convenient; the paint is worthy of being popularized.

Description

technical field [0001] The invention relates to the technical field, in particular to a chlorosulfonated ethylene composite anticorrosion coating added with organic montmorillonite modified zinc powder. 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 tradition...

AI Technical Summary

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
