Problems solved by technology

[0002] Existing inorganic light-storing self-luminous wall and floor tiles generally contain a multi-layer structure in order to obtain a better light-storing and luminous effect, such as a base material, a reflective layer, a light-emitting layer, and a glaze layer. Although this structure can improve the light-storing and luminous effect of the wall and floor tiles , but this also causes defects such as cumbersome manufacturing process and high cost; in addition, because the luminescent layer is directly exposed to the air, when it is used for a long time, it will rub against surface objects to form scratches, which will damage the luminescent layer and affect the luminescent layer. The luminous brightness reduces its luminous effect, thus shortening the service life of self-luminous wall and floor tiles
[0003] The inorganic light-storage self-luminous wall and floor tiles in the prior art have a good light-storage and luminous effect, but for areas with insufficient light, the light-storage and luminous effect is not obvious, and its application scenarios are relatively single
In the existing method for preparing self-luminous wall and floor tiles, when the self-luminous wall and floor tiles are prepared, it is easy to cause cracks in the adobe at the bottom, thereby affecting the quality of the final product and resulting in a high scrap rate
