Abstract

The invention provides a self-cleaning super-hydrophilic ceramic material and a preparation method thereof. The self-cleaning super-hydrophilic ceramic material comprises a first coating and a second body layer, wherein the first coating comprises nano titanium dioxide, nano aluminum trioxide and nano silicon dioxide; and the second body layer comprises quartz, kaolin, aluminum oxide, potassium feldspar, zinc oxide and magnesian mud. The first coating on the surface of the self-cleaning super-hydrophilic ceramic material is thin and can be closely associated with the second body layer, and the nano titanium dioxide in the first coating has photocatalytic activity, so that the self-cleaning of the ceramic material can be realized, and the combination of the first coating, the nano titanium dioxide and the second body layer has super-hydrophilic performance and is beneficial to the removal of oil stains.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a self-cleaning super-hydrophilic ceramic material and a preparation method thereof. Background technique [0002] Super-hydrophilic ceramic tiles are mainly through the organic combination of photocatalytic materials and ceramic tiles to achieve anti-fouling and easy-to-clean effects. The existing combination technologies of photocatalytic nanomaterials and ceramic tiles are mainly divided into two types: one is photocatalytic The catalytic material is coated on the ceramic tile to form a thin film, and the other is to add the photocatalytic material to the glaze and raw materials to prepare the easy-to-clean ceramic tile. Among them, easy-to-clean ceramic tiles are prepared by coating photocatalytic nanomaterials on ceramic tiles. This method is to directly cover photocatalytic nanomaterials on ceramic tiles, and a layer of easy-to-clean film is formed on the surface of cerami...
