Abstract

The invention discloses a high-wear-resistance super-hydrophobic composite coating. The high-wear-resistance super-hydrophobic composite coating consists of the following components in parts by mass:5 to 15 parts of organic silane, 1 to 10 parts of an inorganic wear-resistant agent, 2 to 9 parts of a catalyst, 1 to 3 parts of a hydrophobic agent, 0 to 3 parts of carbon fiber, 0 to 3 parts of glass flake powder, 2 to 8 parts of one or two of tetraethylenepentamine and tetraethylenetriamine and 60 to 90 parts of solvent. The invention also provides a preparation method of the high-wear-resistance super-hydrophobic composite coating as well as a preparation method of a coating layer. The invention has the following beneficial effects: the coating layer continuous phase has high hardness, high wear resistance, high smoothness and superhydrophobicity and also has high compactness and strong binding force with a matrix; and the coating can be used for coating and cured at normal temperature, realizes anti-scouring, anti-fouling, anti-corrosion and anti-ageing effects, is suitable for matrixes such as steel, glass and rubber, can be applied to high-voltage cables, outdoor high-voltage equipment, ships and automobile glass, and can maximally reduce scouring and shearing on the coating layer by seawater, silt and wind sand.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high wear-resistant super-hydrophobic composite coating, a preparation method and a coating made thereof. Background technique [0002] Superhydrophobic surface refers to a surface with a contact angle greater than 150° and a rolling angle less than 10° and has a special wetting effect. It has special functions such as anti-icing, anti-corrosion, and anti-fouling. Self-cleaning and anti-flashover of electrical equipment, application of biomedical and bionic materials, waterproofing and anti-corrosion of pipelines, power transmission towers and cables against ice and snow in winter, and many other fields have broad application prospects. [0003] Although the superhydrophobic coating prepared by the traditional method has a high hydrophobic angle and a low sliding angle, the coating has poor wear resistance and is not suitable for application on the interface with flowing media...
