Modified colemanite and melamine polyphosphate flame-retardant synergistic corrosion-resistant coating

Abstract

The invention discloses modified colemanite and melamine polyphosphate flame-retardant synergistic corrosion-resistant coating. The modified colemanite and melamine polyphosphate flame-retardant synergistic corrosion-resistant coating is prepared from the following raw materials in parts by weight: 60 to 65 parts of chlorosulfonated polyethylene rubber 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 a silane coupling agent KH 560, 2 to 3 parts of lanthanum oxide, 1.5 to 2 parts of dicerium trioxide, a proper amount of a nitric acid solution at the concentration of 65 percent by weight, an ammonium bicarbonate solution at the concentration of 50 percent by weight, 10 to 12 parts of rutile type titanium dioxide, 1.5 to 2 parts of polyalkylene glycol, 2 to 3 parts of sodium-based montmorillonite, 4 to 5 parts of melamine polyphosphate, 4 to 5 parts of colemanite, 1 to 1.5 parts of oleic acid and a proper amount of absolute ethanol. The composition emulsion has flame retardance, high-temperature resistance and excellent adhesive force; a paint film is tough and anti-ageing; the process is simple and convenient in industrial control; and the corrosion-resistant coating is applied to surface corrosion prevention of metal equipment, pipelines, cylinders and the like, and prolongs the service time of equipment.

Description

technical field [0001] The invention relates to the technical field, in particular to an anti-corrosion coating in which modified colemanite cooperates with melamine phosphate for flame retardancy and synergistic effect. 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 pro...

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
