Technical Field
The invention belongs to the technical field of ceramic materials, and relates to a luminescent ceramic material and a preparation method thereof.
Background
The luminescent ceramic is a high-purity high-tech tip material which is prepared by high-temperature high-pressure activation treatment of rare earth materials, can absorb sunlight or other scattered light, can emit strong light by activation after absorbing and storing light energy, has the maximum luminous time of more than 12 hours, can repeatedly reproduce luminous performance, maintains the luminous effect for 15 years, ensures that everything can permanently share a bright piece, and can be doped into paint or resin to prepare paint or injection molding.
The luminous ceramic tile is characterized in that afterglow luminous materials are introduced into the ceramic tile, so that the ceramic tile has the characteristic of continuous luminescence under the dark condition after absorbing external energy. Because the luminescent material has poor high-temperature luminescence property, most of the current luminescent ceramic tiles are secondary-firing or tertiary-firing products, a biscuit firing blank or a fired blank is used as a base material, luminescent glaze is distributed on the surface of the biscuit firing blank or the fired blank, firing is carried out again, and the luminescent ceramic tiles can be prepared, and the current production process needs to consume a large amount of fuel for multiple firing, so that the environment-friendly production requirement is not met, and the production cost is increased.
If the luminescent ceramic tile is calcined for one time, the luminescent material has poor luminescent property at high temperature, low luminescent intensity and short luminescent afterglow time. Therefore, the problem that the luminescent material has poor luminescent performance at high temperature can be solved by one-time calcination.
