Abstract

The invention relates to the technical field of coatings, and provides a modified resin coating which comprises the following components in parts by weight: 50 to 65 parts of liquid resin; 3 to 8 parts of polyaniline; 0.3 to 0.8 part of graphene; 0.5 to 1 part of p-toluenesulfonic acid; 20-25 parts of glass flakes; 5-15 parts of a filler; 1.7 to 3.8 parts of an auxiliary agent; and 11 to 18 parts of a pigment. The obtained modified resin coating does not contain a solvent, is high in solid content, low in VOC, good in corrosion resistance, low in surface treatment cost, environment-friendly and safe, and can be used for construction with rust. The resin coating is suitable for corrosion prevention and renovation of large steel structures and process equipment in petrifaction, bridges, power plants, chemical plants and the like.

Description

technical field [0001] The application belongs to the technical field of coatings, in particular to a modified resin coating and a preparation method thereof. Background technique [0002] Petrochemical, bridges, power plants, chemical plants and other large steel structure buildings and process equipment, in the process of regular maintenance and maintenance, the cost of surface treatment is very high, and some places cannot use electric grinding equipment, such as oil storage tanks, gasoline storage Cans, etc., sparks during grinding are potential safety hazards, and "environmental protection, safety, performance and cost" have gradually become the development trend of this industry. [0003] At present, there are many such coatings on the market, but most of them have low solid content and high VOC (volatile organic compounds), which cause great harm to the environment and also have potential safety hazards. Some products have high requirements for surface treatment, hig...
