Abstract

The invention provides a fluorescent glaze and a preparation method thereof. The fluorescent glaze is mainly prepared from the following raw materials by weight percentage: 50%-70% of glass frit, 20%-40% of feldspar and 2%-15% of calcined kaolin. The preparation method comprises the following steps of: firstly, mixing feldspar, calcium carbonate, barium carbonate, zinc oxide, aluminium oxide, borax, boric acid, quartz, strontium carbonate, vanadium pentoxide and bismuth oxide together in a certain weight ratio and then smelting the mixture at a temperature in the range from 1250 to 1350 DEG C; secondly, forming the glass frit after water quenching; and then enabling the glass frit to be subjected to coarse crushing, fine crushing and dosing grinding orderly, and mixing the ground powder with the feldspar and the calcined kaolin proportionally through a ball mill and grinding evenly, thereby obtaining the fluorescent glaze. The fluorescent glaze provided by the invention is free of rare-earth element, and can be excited under either natural light or a fluorescent lamp; the fluorescent glaze is high in fluorescent brightness and has persistence as long as 1300 min; the process of the preparation method of the fluorescent glaze is simple and capable of well meeting common requirements of the building ceramic industry.

Description

A kind of fluorescence glaze and preparation method thereof

Technical field

The present invention relates to construction sanitary ceramic decoration technique field, what be specifically related to is composition of a kind of fluorescence glaze and preparation method thereof.

Background technology

The research history of embedded photoluminescent material is very long, can trace back to Frenchman Sidot in 1866 the earliest and prepare first and have the long after glow luminous material of practical application meaning
