Problems solved by technology

However, the preparation method of photocatalytic ceramics has the disadvantages of poor bonding between the photocatalytic film and the ceramic substrate, easy to fall off and loss, and the distribution of photocatalyst is uneven, and there are shortcomings such as "rainbow effect", which directly affects the aesthetics of ceramics.
If the photocatalytic titanium dioxide is directly used in the glaze, when the temperature is higher than 900 ° C, the titanium dioxide will lose its photocatalytic activity due to crystal transformation and grain growth.

Description

technical field [0001] The invention relates to the field of building ceramics, in particular to functional ceramic tiles. Background technique [0002] With the improvement of living standards, people's requirements for building decoration are gradually increasing, especially the comfort and health of interior decoration. A series of building materials products with air purification function have emerged as the times require. Humidity-adjusting ceramic tiles absorb and release water vapor through capillary condensation and decondensation through a large number of nano-scale capillary pores on the surface, which play a role in regulating indoor humidity. For example, Chinese invention patent CN103172401A discloses a ceramic wall tile with humidity control function and a preparation method thereof, and Chinese invention patent CN104609830A discloses a building energy-saving passive humidity control function ceramic tile and its production method. At the same time, humidity-...
