Abstract

The invention discloses a modified polyaniline-doped non-corrosibility-improved chlorosulfonated polyethylene anticorrosive coating. The coating is prepared from 60-65 parts by weight of chlorosulfonated polyethylene latex, 35-40 parts by weight of neoprene latex, 7-8 parts by weight of polyoxyethylene aliphatic alcohol ether, an appropriate amount of deionized water, 2.5-3 parts by weight of a silane coupling agent KH560, 2-3 parts by weight of lanthanum oxide, 1.5-2 parts by weight of cerium oxide, an appropriate amount of a nitric acid solution having a concentration of 65wt%, an appropriate amount of an ammonium bicarbonate solution having a concentration of 50%, 10-12 parts by weight of rutile titanium dioxide, 2-2.5 parts by weight of ammonium polyphosphate, 2.5-3 parts by weight of direct fast turquoise blue GL, 2-2.5 parts by weight of polyaniline, an appropriate amount of an acetone solution having a concentration of 50wt%, an appropriate amount of N, N'-dimethyl formamide, and 8 to 10 parts by weight of 12mol / L of hydrochloric acid. The coating has good adhesion, can be distributed evenly on various metal surfaces, has good anti-corrosion effects on the metal, and is durable and efficient. The preparation method of the coating is simple and is easy to industrially control.

Description

technical field [0001] The invention relates to the technical field, in particular to a chlorosulfonated polyethylene anticorrosion coating with enhanced anticorrosion doped modified polyaniline. 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 form...
