Document Type and Number:
WIPO Patent Application WO/2024/046129
Kind Code:
A1
Abstract:
A self-cleaning ceramic coating of a lotus-leaf-like structure, a preparation method therefor and an application method thereof. The self-cleaning ceramic coating comprises, based on 100% of the total weight: 25-27% of silica sol, 4-5% of a 1% NaOH solution, 10-12% of pigment, 8-10% of a filler, 1-1.2% of a dispersing agent, 25-27% of silane, 3-3.5% of isopropanol, 6-8% of silicone oil microcapsules, and 0.7-1% of 25% formic acid, with the balance being deionized water. By forming a micron-nano secondary roughness structure on the surface of the ceramic coating and preparing silicone oil microcapsules of a shell-core structure, the water contact angle of the ceramic coating is greater than 150° and the rolling angle thereof is greater than 140°; therefore, the ceramic coating has excellent super-hydrophobicity and self-cleaning performance, and has good durability.
