ANTI-STATIC CERAMIC TILE HAVING NANOSTRUCTURE ON SURFACE AND PREPARATION METHOD

WIPO Patent Application WO/2022/011932

A1

An anti-static ceramic tile having a nanostructure on the surface and a preparation method. The method comprises the following steps: S1, preparing a certain concentration of weak acid according to the requirement of a microstructure on the surface of a ceramic tile (1); S2, using a high-pressure atomization device to uniformly spray the weak acid to the surface of the ground and polished ceramic tile (1) for modification of the microstructure on the surface; S3, performing cleaning and blow-drying on the surface of the modified ceramic tile (1); S4, preparing a nano-silicon dioxide aqueous solution doped with silver particles; and S5, coating the nano-silicon dioxide aqueous solution doped with the silver particles on the surface of the modified ceramic tile to form a thin film layer (2), and performing baking; and S6, performing cooling after baking to obtain the anti-static ceramic tile. The present invention has the characteristics of low difficulty in production technology, easy implementation, and high cost performance.
