Abstract

The invention discloses a high wear-resistant super-hydrophobic composite coating, which consists of the following components in parts by mass: 5-15 parts of organosilane, 1-10 parts of inorganic anti-wear agent, 2-9 parts of catalyst, and 1-3 parts of hydrophobic agent 0-3 parts of carbon fiber, 0-3 parts of glass flake powder, 2-8 parts of one or both of tetraethylenepentamine and tetraethylenetriamine, 60-90 parts of solvent; the present invention also provides a A preparation method of a high wear-resistant super-hydrophobic composite coating and a preparation method of the coating. The beneficial effects of the present invention are: the coating continuous phase of the present invention has high hardness, high wear resistance, high smoothness and superhydrophobicity, and has high compactness and strong bonding force with the substrate at the same time. The coating of the present invention can Coating and curing at room temperature to achieve anti-scouring, anti-fouling, anti-corrosion, anti-aging and other effects, suitable for steel, glass, rubber and other substrates, can be used for high-voltage cables, outdoor high-voltage equipment, ships, automotive glass, etc., to minimize seawater, The erosion and shearing of the coating by sediment and wind and 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...
