Problems solved by technology

[0002] The outer surface of existing steel storage tanks is coated with synthetic resin coatings. The disadvantages are that the salt spray resistance and light aging resistance are not good, and the coating is prone to pitting and discoloration. The artificial accelerated salt spray test of synthetic resin coating is generally 500h, and the artificial accelerated light aging test is generally 600h

Abstract

The invention relates to a modified chlorosulfonated polyethylene rubber coating used for steel storage tanks and a preparation method thereof. The coating comprises a component A and a component B, wherein the component A is composed of chlorosulfonated polyethylene rubber, dimethylbenzene, trimethylbenzene, titanium white powder, talc powder, fluorocarbon-modified polyacrylamide and organic bentonite; and the component B is composed of bisphenol-A epoxy resin, dimethylbenzene, n-butanol, diphenyl guanidine (manufactured by Dongbei Auxiliary general factory, Shenyang) and ethylenethiourea. The component A and the component B are mixed and cured to form a coating film before application. The coating is excellent in physical property, chemical resistance, salt spray resistance and light fastness, and can be used for the surface protection and coating of steel storage tanks in various corrosive environments.

Description

technical field [0001] The invention relates to a modified chlorosulfonated polyethylene rubber coating used for protecting and coating the outer surface of steel storage tanks under various corrosive environments and a preparation method thereof. Background technique [0002] The outer surface of existing steel storage tanks is coated with synthetic resin coatings. The disadvantages are that the salt spray resistance and light aging resistance are not good, and the coating is prone to pitting and discoloration. The artificial accelerated salt spray test of the synthetic resin coating is generally 500h, and the artificial accelerated light aging test is generally 600h. Contents of the invention [0003] The technical problem to be solved by the present invention is to avoid the shortcomings of the above-mentioned prior art and provide a simple and convenient manufacturing method, which can be dried and formed at room temperature, and the coating film has excellent physical...
