Abstract

The invention relates to the field of super-hydrophobic surface coatings, in particular to an organic composite super-hydrophobic coating and a preparation method thereof. The organic composite super-hydrophobic coating comprises the following components: spherical silica sol and hydrophobic spherical silica; a halogenating agent, an organic solvent and a coating sol; the spherical silicon dioxide sol comprises tetraethoxysilane, ethanol and ammonium hydroxide, and the hydrophobic spherical silicon dioxide comprises gamma-aminopropyl triethoxysilane and octadecyl methoxysilane; the halogenating agent is carboxylic acid or acyl halide of halogen; the organic solvent is one of anisole, tetrahydrofuran, dimethylformamide, dimethyl sulfoxide, sulfolane and ethylene nitrate; the coating sol comprises a metal material, a composite material, silicon dioxide, epoxy resin and methylbenzene. The coating has multiple functions of super-hydrophobicity, self-cleaning property, icing resistance and the like, and the preparation method is simple, practical, low in cost and convenient to use, is suitable for enterprise implementation and large-scale production and application, and has wide social benefits and economic values.

Description

technical field [0001] The invention relates to the field of super-hydrophobic surface coatings, in particular to an organic composite super-hydrophobic coating and a preparation method thereof. Background technique [0002] Surface properties are one of the most important physical and chemical properties of solid materials, and wettability is a major aspect of the surface properties of materials. In recent years, super-hydrophobic surfaces have attracted widespread attention. 150o, and the roll angle is less than 10o surface. Due to the small contact area between the super-hydrophobic surface and water droplets, water droplets can easily slip off the surface. It has broad application prospects in many fields such as anti-frost, anti-frost, anti-icing, anti-adhesion and anti-fouling. Studies have shown that superhydrophobic surfaces have low surface energy and high surface roughness, and superhydrophobic surfaces can be obtained by adjusting the chemical composition and su...
