Modified anticorrosive chlorosulfonated polyethylene coating with polyaniline loaded on surfaces of zeolite molecular sieves

Abstract

The invention discloses a modified anticorrosive chlorosulfonated polyethylene coating with polyaniline loaded on the surfaces of zeolite molecular sieves. The coating is made of, by weight, 60-65 parts of chlorosulfonated polyethylene latex, 35-40 parts of neoprene latex, 7-8 parts of polyoxyethylene fatty alcohol ether, an appropriate amount of deionized water, 2.5-3 parts of silane coupling agents KH560, 2-3 parts of lanthanum oxides, 1.5-2 parts of cerous oxides, an appropriate amount of nitric acid solutions with the concentration being 65wt%, an appropriate amount of ammonium bicarbonate solutions with the concentration being 50wt%, 10-12 parts of rutile titanium dioxides, 1-1.2 parts of silicone emulsion, 2-3 parts of aniline, 0.1-0.12 part of ammonium persulfate, 4-5 parts of the zeolite molecular sieves, 0.3-0.4 part of sodium dodecyl benzene sulfonate and an appropriate amount of absolute ethyl alcohol. The manufactured coating has the advantages that an technology and equipment are simple, industrial production is easy, product construction is convenient, and the adhesive force and the quick-drying performance are excellent. The coating can be used on the surface of steel body structure and chemical pipeline equipment and has good preservative effect.

Description

technical field [0001] The invention relates to the technical field, in particular to a polyaniline-loaded zeolite molecular sieve-modified chlorosulfonated polyethylene anticorrosion coating. 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...
