Abstract

The invention relates to the technical field of ceramic materials and particularly relates to a building wall tile modified by a superhydrophobic nanotechnology and a preparation method thereof. The wall tile comprises a green tile substrate and ceramic glaze coating the surface of the green tile substrate. The ceramic glaze is prepared from 70-80 parts by weight of glass frit, 7-15 parts by weight of metal copper microparticles, 2-8 parts by weight of Fe2O3 microparticles, and 5-10 parts by weight of kaolin. Through a spray-coating method, the prepared suspension liquid coats the surface of the green tile substrate. The building wall tile has strong super hydrophobic performances, antibacterial effects and friction resistance.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a building wall tile modified by superhydrophobic nanotechnology and a preparation method thereof. Background technique [0002] In recent years, with the urgent need for energy saving and improving the durability of building materials, the application and development of superhydrophobic building materials is imminent. Nano-hydrophobic ceramic glazes can be preformed by adding metal nanoparticles loaded on sepiolite fibers. This method is basically consistent with the standard manufacturing process of tiles, but the nanoparticles of sepiolite on metal are due to high product cost and low market supply. A new challenge is to develop new nano-functional glazes using existing materials on the market. At present, self-cleaning surface products will be a relatively high-end product in the market, both for the public and for manufacturing companies. The main issues that ha...
