Abstract

The invention discloses a bottom surface-integrated wear-resistant fluorosilicone-based super-amphiphobic coating, and a preparation method and application thereof. The preparation method comprises the following steps: 1) performing synergistic modification treatment on two or more nanoparticles to obtain modified blended particles; 2) adding the blended modified particles into a dispersing solvent, performing ultrasonic dispersion for 1 to 2 hours and then mechanically stirring; 3) adding a certain amount of tert-butyl acetate into fluoro-siloxane resin and performing shearing dispersion to obtain substrate material emulsion; 4) mixing the blended modified particle turbid liquid in the step 2 and the substrate material emulsion in the step 3, adding a coupling agent, heating, stirring anddispersing, and performing dispersion by a high-speed shearing dispersing machine to obtain super-amphiphobic coating; and 5) stirring the super-amphiphobic coating uniformly, spray-coating the surface of an object with the super-amphiphobic coating and drying at room temperature for 10 to 30 minutes to successfully prepare the wear-resistant integrated super-amphiphobic coating. The wear-resistant super-amphiphobic organic-inorganic hybrid coating is obtained by connecting a fluorine-silicon substrate and the blended modified particles through chemical grafting copolymerization reaction.

Description

technical field

[0001] The invention belongs to the field of preparation of super-amphiphobic coatings, and in particular relates to a bottom integrated wear-resistant fluorine-silicon-based super-amphiphobic coating and a preparation method and application thereof. Background technique

[0002] Superhydrophobic coating refers to coating one or more layers of superhydrophobic materials on a solid surface to have a high water contact angle (>150°) and a low rolling angle (<10°) to achieve its anti-corrosion, waterproof and Anti-icing and other functions. Due to its excellent hydrophobicity, the super-hydrophobic coating is coated on the outside of metal components, which reduces the surrounding water vapor and can achieve anti-corrosion functions; in the case of freezing rain and snowfall, the super-hydrophobic surface maintains a non-icing state or reduces the adhesion of the ice layer. Focusing on preventing or delaying the icing of transmission lines and preparing s...
