If the product is poor in antifouling effect, a user can leave a lot of dirt on the surface of the product after using the product for a period of time, visual sensation is influenced, and user experience is not good.
Antifouling glaze tiles currently on the market: (for example, Chinese patent ZL201710714237.X) is composed of albite, quartz powder, calcite, talcum powder, calcined kaolin, zirconium white frit, alumina powder and zirconium silicate. The antifouling ceramic tile has high glossiness (more than 70 degrees) and smooth surface, and the surface of the antifouling ceramic tile is treated to fill the surface holes to achieve an antifouling effect and improve the glossiness of the surface of the ceramic tile. The antifouling technologies are intelligently applied to products with high glossiness, but the ceramic tiles such as wood-like tiles, stone-like tiles, antique tiles and the like require the surface glossiness to be as low as possible, and some products require rough surface texture, so that the antifouling technologies are difficult to apply to the ceramic tile products. In addition, the low-gloss dry grain glaze is applied to the green brick, although the low-gloss matte effect can be achieved, the dry grain glaze has high melting temperature and poor melting property, so that the surface of the ceramic brick has more micropores, is easy to store dirt and dirty and is difficult to clean.
