Problems solved by technology

The above methods can be prepared to achieve the expected super-hydrophobic surface effect, but in the process of use, the rough micro-nano structure is easily damaged under the action of mechanical friction or wear, thereby reducing the super-hydrophobic performance or causing it to lose the super-hydrophobic performance.

Abstract

The invention belongs to the technical field of anti-corrosion coatings, and relates to a single-component super-hydrophobic wear-resistant anti-corrosion coating and a preparation method thereof. The technical key points are as follows: the coating comprises the following components in percentage by mass: 40-60% of fluorine-containing matrix resin, 20-40% of a solvent, 0.5-5% of graphene, 5-10% of modified silicon dioxide, 0.1-3% of a flatting agent, 0.1-3% of a defoaming agent, 0.1-3% of a dispersing agent and 0.1-3% of a coupling agent. According to the single-component super-hydrophobic wear-resistant anti-corrosion coating provided by the invention, by utilizing the special wettability of a super-hydrophobic surface, an air cushion is formed between water and a coating layer when the water is in contact with the surface of the coating layer, the water is difficult to permeate into the surface of a base material to corrode the surface of the base material, and the wear-resistant super-hydrophobic coating is prepared by combining fluorine-containing matrix resin and a silicon dioxide material, so that the super-hydrophobicity has durability.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion coatings, and relates to a single-component superhydrophobic wear-resistant anti-corrosion coating and a preparation method thereof. Background technique [0002] Superhydrophobic surfaces are usually achieved through the modification of low surface energy substances and micro-nano rough structures. Due to the special wettability of the superhydrophobic surface, the superhydrophobic surface has the characteristics of self-cleaning and surface anticorrosion. The preparation methods of super-hydrophobic surfaces are becoming more and more diverse, such as the hydrophobic modification of the surface of the substrate by fluorosilicon, so that the surface of the substrate has super-hydrophobic properties. The micro-nano structure on the surface of the lotus leaf can also be copied by the prepolymer of polydimethylsiloxane to make a polydimethylsiloxane template, and a super-hydrophobic surface ...
