Abstract

The invention relates to a chlorinated polyether resin coating and a production method thereof. The coating contains 1 weight part of chlorinated polyether resin, 0.025-0.5 weight parts of chlorinated paraffin wax with chlorine content of 52%, 0.008-0.5 weight parts of acrylic acid-modified fluorocarbon resin, 0.05-3.0 weight parts of dimethylbenzene, 0.01-1.2 weight parts of heavy aromatic solvent, 0.005-0.01 weight parts of dimethyl silicon oil, 0.005-0.25 weight parts of aluminum tripolyphosphate, 0.006-0.5 weight parts of titanium white powder, 0.01-0.4 weight parts of talc powder and 0.005-0.05 weight parts of organic bentonite. The coating is characterized in that: the components are packaged independently and are dried at room temperature to form coating. 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 structure and concrete in corrosive marine environments.

Description

technical field [0001] The invention relates to a chloroether resin coating used for protecting and coating steel structures and concrete surfaces under marine corrosion environments 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 720h, and the artificial accelerated light aging test is generally 800h. Contents of the invention [0003] The purpose of the present invention is to provide a kind of simple and convenient manufacturing method, with single-component packaging, room temperature drying film forming characteristics, its coating film has excellent physical properti...
