Abstract

The invention relates to a fluorosilicone-modified acrylic resin hydrophobic anti-corrosion paint which is characterized in that the paint comprises a component A and a component B in parts by weight, wherein the component A comprises 45-70 parts of hydrophobic resin, 5-40 parts of pigments and fillers, 6-30 parts of solvent, 1-3 parts of anti-aging agent, 1-5 parts of dispersant, and 0.5-2 parts of anti-settling agent, and the component A is prepared by mixing, grinding and stirring; and the component B comprises 5-8 parts of curing agent. The paint has the characteristics of good hydrophobic property, good adhesion, strong anti-photoaging property, strong flexibility, self-cleaning property, good corrosion resistance, excellent performances and the like, is convenient for construction and can be coated for a large area.

Description

[technical field] [0001] The invention relates to coatings, in particular to a hydrophobic anti-corrosion coating of fluorine-silicon modified acrylic resin which can be used for anti-corrosion of steel structure or hot-dip galvanized steel. [Background technique] [0002] Hydrophobic coatings can make the dust on the surface not adhere firmly and be easily carried away by rainwater, thus making the surface self-cleaning. Coatings with hydrophobic properties can reduce the residence time of moisture and dust on its surface, and reduce the reaction of the surface with water or chemicals in pollution. Therefore, the ion diffusion resistance and permeability of its coating will be greatly improved. [0003] Organic fluorine resin is the resin material with the lowest surface energy known so far, and the surface tension of perfluoroalkanes can be reduced to about 6mN / m, but there are problems such as high temperature curing and long curing time. Acrylic resin is a kind of coat...
