Abstract

The invention discloses a fluorosilicone resin / composite modified nano-material hybrid superamphiphobic coating and a preparation process thereof. The coating materials used include fluorosilicone resin, a dispersing solvent, and a composite modified nano-SiO 2 -TiO 2 Particles, coupling agent 1 and defoamer; composite modified nano-SiO 2 -TiO 2 The preparation method of the particles is, the nano-SiO 2 with nano TiO 2 Perform ball milling and mixing to obtain mixed nano-powder, add mixed nano-powder and surfactant to solvent 1 for dispersion to obtain mixed nano-powder dispersion, add coupling agent 2 to the mixture of solvent 1 and water to obtain coupling agent hydrolyzate , add the coupling agent hydrolyzate dropwise to the mixed nano-powder dispersion, stir and heat the reaction to obtain composite modified nano-SiO 2 -TiO 2 particle. Rely on SiO 2 -TiO 2 The composite modification of nanoparticles can greatly increase the amount of particles added without affecting other properties of the coating, so as to achieve technical purposes such as truly effective superamphiphobic, wear-resistant, and simple preparation processes for fluorosilicon coatings.

Description

technical field [0001] The invention relates to the field of preparation of super-amphiphobic coatings, in particular to a wear-resistant fluorosilicone resin / composite modified nano-SiO 2 -TiO 2 Hybrid superamphiphobic coating and its preparation process. 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, Anti-icing and other functions. Due to its excellent hydrophobicity, the super-hydrophobic coating can be coated on the outside of metal components to reduce the surrounding of water vapor and achieve anti-corrosion function; in the case of freezing rain and snowfall, the super-hydrophobic surface remains in a non-icing state or reduces the adhesion of the ice layer , to prevent or delay the icing of transmission lines, and to prepare superhydrophobic coatings ...
