Modified zinc oxide antibiosis and mildew-resistance enhanced chlorosulfonated polyethylene anticorrosion coating

Abstract

The invention discloses a modified zinc oxide antibiosis and mildew-resistance enhanced chlorosulfonated polyethylene anticorrosion coating, which is prepared from the following raw materials (by weight): 60-65 parts of chlorosulfonated polyethylene latex, 35-40 parts of neoprene latex, 7-8 parts of polyoxyethylene aliphatic alcohol ether, a proper amount of deionized water, 2.5-3 parts of a silane coupling agent KH560, 2-3 parts of lanthana, 1.5-2 parts of dicerium trioxide, a proper amount of a nitric acid solution with concentration being 65 wt%, an ammonium bicarbonate solution with concentration being 50 wt%, 10-12 parts of rutile titanium dioxide, 2-3 parts of aluminium triphosphate, 5-6 parts of cassia oil, 3-4 parts of barium metaborate, 3-4 parts of zinc nitrate, 3-4 parts of hexamethylene tetramine, 4-5 parts of stearic acid and a proper amount of anhydrous ethanol. The prepared composite anticorrosion coating is full water-borne and environment friendly, has good synergistic effect of various components, has short film-forming drying time, good hardness, corrosion resistance, weather resistance and excellent film adhesion, and can be used for anticorrosion of outdoor pipelines, metal machinery equipment and chemical equipment.

Description

technical field [0001] The invention relates to the technical field, in particular to a chlorosulfonated polyethylene anticorrosion coating with enhanced antibacterial and antifungal properties of modified zinc oxide. 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 produc...

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
