Abstract

The invention discloses a super-hydrophobic paint, which is composed of the following components by mass: 5-15 parts of organosilane, 1-10 parts of an inorganic wear-resistant agent, 2-9 parts of a catalyst, 1-3 parts of a hydrophobic agent, 2-8 parts of one or two of tetraethylenepentamine and tetraethylenetriamine and 60-90 parts of a solvent. The beneficial effects of the invention are that: acoating continuous phase of the paint provided by the invention has high hardness, high wear resistance, high smoothness and super-hydrophobicity, at the same time the coating has high compactness andstrong combing power to a matrix. The paint provided by the invention can be coated and cured at room temperature, realizes scouring resistance, fouling resistance, corrosion resistance, aging resistance and other effects, is suitable for steel, glass, rubber and other matrixes, can be used for high-voltage cables, outdoor high-voltage equipment, ships, automobile glass and the like, and reducesthe scouring and shearing of seawater, silt and sandstorm to the coating to the maximum extent.

Description
