Abstract

The present invention relates to a transparent wear-resistant super-hydrophobic coating material, a preparation method and a coating process thereof. The transparent wear-resistant super-hydrophobic coating material comprises a nanometer material dispersion liquid and an adhesion material dispersion liquid. According to the present invention, during the preparation, a nanometer material and a volatile solvent are mixed and dispersed to prepare the nanometer material dispersion liquid, and the adhesion material and the good solvent thereof are mixed and dispersed to prepare the adhesion material dispersion liquid; during the coating, the substrate surface is cleaned, the adhesion material dispersion liquid is coated to form the adhesion layer, the nanometer material dispersion liquid is coated after drying, the partial nanometer material is embedded into the adhesion layer through heating, pressurization and other ways, and finally the unstably-binding nanoparticles are removed by using scraping or adhesive tape adhesion to obtain the super-hydrophobic coating, wherein the coating has characteristics of good transparency, strong binding force, and wear resistance; and the super-hydrophobic coating material of the present invention can be used for the surfaces of a variety of materials such as metals, plastics, glass, cement boards and the like so as to achieve functions of water resistance, stain resistance, corrosion resistance, self-cleaning, dew resistance, icing resistance, and the like.

Description

technical field [0001] The invention belongs to the technical field of preparation and application of super-hydrophobic surfaces, and in particular relates to a transparent wear-resistant super-hydrophobic coating, a preparation method and a coating process thereof. Background technique [0002] The phenomenon of superhydrophobicity exists widely in nature, such as lotus leaves, butterfly wings, water strider legs, etc. all show excellent superhydrophobicity. The superhydrophobic coating is composed of a micro-nano-scale structure and a surface with low surface energy, and has the characteristics of a static contact angle of water greater than 150° and a rolling angle of less than 10°. Research on superhydrophobic surfaces has been one of the frontiers and hotspots of international scientific research in the past two decades. A breakthrough has been made. Common superhydrophobic structures such as ordered microcolumns, porous structures, nanowires, micronanoparticle cluste...
