Problems solved by technology

[0002] The surface of the steel structure in the existing marine corrosive environment 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. For internal and external peeling, the artificial accelerated salt spray test of the synthetic resin coating is generally 500h, and the artificial accelerated light aging test is generally 600h

Abstract

The invention relates to acrylic acid modified chlorinated rubber coating and a method for preparing the same. The coating consists of: 1 weight portion of chlorinated rubber, 0.05 to 0.4 weight portion of acrylic acid resin, 0.005 to 1.03 weight portions of chlorinated paraffin, 0.08 to 0.5 weight portion of epoxy resin, 0.05 to 3.0 weight portions of dimethylbenzene, 0.01 to 1.5 weight portions of heavy aromatic solvent, 0.005 to 0.045 weight portion of fluoro-carbon modified acrylic acid resin, 0.006 to 0.5 weight portion of titanium white powder, 0.01 to 0.8 weigh portion of talcum powder, and 0.005 to 0.05 weight portion of organoclay. The coating has the characteristics of single composition packing and drying film formation under normal temperature. A paint film of the coating has excellent physical property, chemical resistance, salt spray resistance and anti-photoaging property, and can be used for the protection and coating of the surfaces of steel structures under the environment of marine corrosion.

Description

technical field [0001] The invention relates to an acrylic modified chlorinated rubber coating used for protecting and coating the surface of a steel structure in a marine corrosion environment and a preparation method thereof. Background technique [0002] The surface of the steel structure in the existing marine corrosive environment 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. For internal and external peeling, the artificial accelerated salt spray test of the synthetic resin coating is generally 500h, and the artificial accelerated light aging test is generally 600h.
