Description

Luminescent ceramic with high afterglow intensity and preparation method thereof
Technical Field
The disclosure relates to the technical field of ceramics, in particular to a luminescent ceramic with high afterglow intensity and a preparation method thereof.
Background
The light-storing energy-saving luminous ceramic tile can absorb visible light such as sunlight or lamplight and store light energy, and when light excitation is stopped, the stored energy is slowly released in the form of light for several hours or even tens of hours. The luminous ceramic tile has the advantages of super-long afterglow luminescence, high luminous brightness, long luminous time, no radioactivity and the like, can be used for warning signs of building decoration facilities and public place safety channels, can also be used for concealed illumination and low-degree emergency illumination, and brings great convenience to night life and engineering operation of people.
At present, light-storing energy-saving luminous ceramic tiles mainly have two ways to realize the light-storing energy-saving function. Firstly, mixing luminescent materials, organic solvents such as resin and the like according to a certain proportion to prepare a coating, and coating the coating on the surface of a ceramic tile to form a luminescent coating; and secondly, mixing the luminescent material and glaze powder by a wet method to prepare luminescent glaze, and applying the luminescent glaze cloth on the surface of the ceramic tile by using the processes of slurry spraying, wet screen printing and the like. The high polymer material in the luminescent coating is influenced by pollutants in the air, particularly acid rain and alkali rain, and phenomena such as chalking and the like can occur, so that the appearance quality is poor, and the luminescent intensity is reduced. The luminescent material in the luminescent glaze is easy to hydrolyze, the hydrolysis degree of heat treatment is increased, and the loss of luminescent intensity is large. Meanwhile, the wet glazing process has requirements on the granularity of the luminescent material, the smaller the granularity is, the more favorable the stable suspension of the glaze slurry is, but the luminescent material with small granularity is damaged by grinding processing, and the luminescent intensity is not high. Therefore, the luminescent ceramic tile prepared by applying the luminescent glaze by the wet method has poor luminescent afterglow performance.
