Description

High-adhesion long-acting anti-fouling industrial anticorrosive paint

Technical Field

The utility model belongs to the technical field of the industrial paint technique and specifically relates to a long-term anti-soil industrial anti-corrosion paint of high adhesive force.

Background

The industrial anticorrosive paint is generally applied to the protection and decoration of equipment, ships, containers, bridges, gas tanks, port machinery, chemical equipment, railway tank cars, electric machinery, storage tanks, inner walls of pipelines, various steel structures, concrete and the like produced by industrial enterprises. However, when applied to general environments, the conventional common industrial anticorrosive paint can effectively exert the anticorrosive performance and has strong adhesive force, however, when applied to severe environments, such as conveying pipelines and sewage treatment pools buried under the ground all the year round, the anticorrosive effect is poor (the coating is easy to crack and fall off under humid and severely corroded environments), and the common industrial anticorrosive paint generally does not have the long-acting antifouling capacity.
