Abstract

The invention discloses a high-wear-resistance super-amphiphobic nanometer coating layer, and a preparation method thereof, and belongs to the technical field of ultra infiltration functional coatinglayer material preparation. The preparation method comprises following steps: first, a resin is dissolved in a volatile organic solution, a pore forming agent is added into the volatile organic solution, continuous mechanical stirring is carried out for uniform dispersion of the pore forming agent, then the surface of a substrate is coated with an obtained mixture, then is coated with a super-amphiphobic nanometer coating material, and is introduced into a baking oven for curing of the pore forming agent so as to obtain the high-wear-resistance super-amphiphobic nanometer coating layer. The preparation method can be used on substrates such as wood, cement, and glass, the wear resistance of the high-wear-resistance super-amphiphobic nanometer coating layer is improved obviously, a problem in the prior art that hydrophobic surface is easily destroyed is solved, and under severe environment, coating layer stain resistance, self cleaning performance, fogging resistance, ice resistance, corrosion resistance, and mildew resistance are maintained. The preparation technology and equipment are simple; operation is convenient; cost is low; and the preparation method is suitable for large scale preparation and industrialized production.

Description

technical field [0001] The invention belongs to the technical field of preparation of super-wetting functional coating materials, and in particular relates to a high wear-resistant super-amphiphobic nano-coating and a preparation method thereof. Background technique [0002] Super-amphiphobic surface refers to the solid surface on which water droplets or oil droplets can roll off under the action of micro-dynamic forces under the combined action of surface micro-nano structures and low surface energy substances. It has three defenses (waterproof, oilproof, dustproof), anti Excellent comprehensive properties such as dew, drag reduction, corrosion resistance, etc., can be widely used in industrial fields such as three-proof fabrics, anti-dew and anti-frost for air conditioners, anti-bacterial and anti-mildew for building materials, oil-water separation, anti-bioadhesion interfaces and water collection systems .

AI Technical Summary

Problems solved by technology

However, the superhydrophobic surface micro-nanostructure is easily damaged by abrasion, which affects the superhydrophobicity, thus limiting the application of superhydrophobic surfaces.

Especially for coatings prepared by inorganic nanoparticle superhydrophobic coatings, the inorganic nanoparticles are bonded by molecular bonds, and the binding force is weak; and the inorganic nanoparticles are simply physically adsorbed on the surface of the substrate, and the coating adhesion is poor, resulting in the coating Micro and nanostructures are more susceptible to damage

According to research in recent years, the use of resin as the bottom layer to bond superhydrophobic nanoparticles can improve the wear resistance of superhydrophobic coatings, but the degree of improvement is limited.
