The invention discloses an integrated wear-resistant fluorosilicone-based superamphiphobic coating on the bottom surface and its preparation method and application, comprising the following steps: 1) synergistic modification treatment of two or more kinds of nanoparticles to obtain modified blending Particles; 2) Add the blended modified nanoparticles into the dispersing solvent, ultrasonically disperse for 1‑2h, and then mechanically stir; 3) Add a certain amount of tert-butyl acetate to the fluorosilicone resin for shear dispersion to obtain the base material emulsification 4) mixing the blended modified nanoparticle suspension in step 2 and the base material emulsion in step 3, adding a coupling agent, heating and stirring to disperse, and then using a high-speed shear disperser to disperse to obtain Super-amphiphobic coating; 5) Stir the super-amphiphobic coating evenly, spray it on the surface of the object, and dry it at room temperature for 10-30 minutes to successfully prepare the wear-resistant integrated super-amphiphobic coating. The invention is a superamphiphobic organic-inorganic hybrid coating formed by connecting a fluorosilicon substrate and a blended modified particle through a chemical graft copolymerization reaction. |
