Abstract

See full text

A multicolor light-storing ceramic for fire-protection indication and a preparation method thereof are provided. The preparation method includes: adding a glass based raw material, a light-storing powder, a dispersant and an alumina powder into a granulator, adding water mixed with a pore-forming agent and then mechanically stirring for granulation; adding a plasticizer after the stirring of 4˜8 h, and continuing the stirring for 1˜3 h to thereby obtain a mixture; packing the mixture into a mold and performing tableting; demolding and obtaining a light-storing self-luminous quartz ceramic by drying and firing using a kiln; printing a pattern onto a surface of the ceramic and then curing to obtain a light-storing ceramic for indication sign. Using an industrial waste glass has advantages of low sintering temperature and green environmental protection; dispersed pores and alumina introduced as scattering sources improves light absorption efficiency, fluorescence output phase ratio and light transmission of the ceramic.
