The invention provides a two-component super-hydrophobic coating which comprises a primer and a finish, wherein the primer comprises the following raw materials in parts by weight: 100-150 parts of acrylate resin, 20-35 parts of hydantoin epoxy resin, 110-150 parts of inorganic hydrophobic filler, 80-150 parts of diluent and 2-5 parts of curing agent; the finish paint comprises the following raw materials in parts by weight: 2-5 parts of silicate ester, 7-12 parts of fluorine-containing silane, 15-20 parts of fluorine-containing acrylic resin, 2-5 parts of inorganic hydrophobic filler, 0.5-1 part of organic tin catalyst and 60-80 parts of finish solvent; the polymerized monomer in the fluorine-containing acrylic acid-based resin comprises acrylic acid- (fluoroalkoxyphenyl) alkyl ester shown in a structure of formula (I). The two-component super-hydrophobic coating has beneficial super-hydrophobic performance, can maintain excellent super-hydrophobic performance for a long time in high-temperature, high-humidity and high-salinity environments, and is particularly suitable for waterproof, moistureproof and anti-condensation coatings of electrical cabinets. |
