Problems solved by technology

Although the current low surface energy antifouling coatings have good antifouling effects, most of the existing low surface energy antifouling coatings can only target a certain kind or a certain type of pollution, and cannot be antifouling at the same time. "Four prevention" functions of self-cleaning, anti-graffiti, anti-sticking and anti-corrosion
In addition, the existing low surface energy antifouling coatings have good initial graffiti imitation and anti-sticking properties, but after high-temperature treatment, repeated pasting or several times of graffiti cleaning, their functions are greatly lost, which is manifested in the loss of gloss of the coating, The surface adhesion is increased, the graffiti is not easy to be removed, the coating film falls off, the weather resistance is poor, and the actual outdoor service life is very short

Abstract

The invention discloses a multi-effect antifouling paint, which comprises component A and component B. The component A comprises the following components in parts by weight: 40-45 parts of fluorosilicon modified polyester resin, 0.5 parts of antistatic agent ~2 parts, 0.5~2 parts of hydrophobic recovery agent, 0.5~2 parts of anti-mildew and anti-algae agent, 0.5-2 parts of leveling agent, 0.5-2 parts of wetting and dispersing agent and 2-5 parts of defoaming agent; Component B includes 30-50 parts of polyisocyanate prepolymer; the mass ratio of the component A to the component B is 4-10:1; the fluorosilicon-modified polyester resin contains hydroxyl groups. The multi-effect protective coating not only has the functions of anti-corrosion, anti-fouling self-cleaning, anti-graffiti, and anti-sticking through the synergistic effect of fluorosilicon modified polyester resin, polyisocyanate prepolymer and various functional additives, but also has comprehensive performance excellent. The invention also discloses a construction method of the multi-effect antifouling paint.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a multi-effect antifouling coating and a construction method thereof. Background technique [0002] Small street advertisements and graffiti have become an incurable disease that the government and citizens hate, especially in public places or tourist attractions with a large number of people. It also consumes a lot of human and financial resources. [0003] Multi-effect antifouling coatings with anti-fouling self-cleaning, anti-graffiti and anti-sticking properties have been applied in municipal engineering and achieved good results. Existing antifouling coatings such as anti-fouling self-cleaning, anti-graffiti, and anti-sticking are mostly low surface energy materials. From the perspective of coating matrix resin, low surface energy antifouling coatings can be mainly divided into: silicone, Organic fluorine and fluorine silicon. Silicone usually refers to polys...
