Embodiment 1

[0025] This embodiment 1 provides a fluorescent glaze, the raw materials of which include, by weight, 70 parts of long-lasting phosphor powder; 40 parts of borax; 3 parts of glass powder; and 0.8 part of zinc oxide. The preparation method of the fluorescent ceramic product made from the fluorescent glaze is as follows:

[0026] (1) Mix the components of the raw materials evenly, mix them in the ratio of material: ball: water = 1:2:0.8, put them in a ball mill for ball milling for 8 hours, add water to the mixture after ball milling to make a glaze slurry, and age for 3 hours , get fluorescent glaze;

[0027] (2) Coating the above-mentioned fluorescent glaze on the surface of a non-glazed ceramic product, putting it into an electric furnace, calcining at 950° C., and then cooling naturally to obtain the fluorescent ceramic product.

Embodiment 2

[0029] This embodiment 2 provides a fluorescent glaze, and its raw materials include, by weight, 60 parts of long-lasting phosphor powder; 38 parts of borax; 2 parts of glass powder; and 0.5 part of zinc oxide. The preparation method of the fluorescent ceramic product made from the fluorescent glaze is as follows:

[0030] (1) Mix the components of the raw materials evenly, mix them in the ratio of material: ball: water = 1:2:0.8, put them in a ball mill for ball milling for 6 hours, add water to the mixture after ball milling to make a glaze slurry, and age for 4 hours , get fluorescent glaze;

[0031] (2) Coating the above-mentioned fluorescent glaze on the surface of the finished ceramic product without glaze, putting it into an electric furnace for calcination at 900° C., and then cooling naturally to obtain the crude fluorescent ceramic;

[0032] (3) Coating transparent glaze on the surface of the rough fluorescent ceramic product, calcining at 880° C., and then cooling ...

Embodiment 3

[0035] Embodiment 3 provides a fluorescent glaze, and its raw materials include, by weight, 50 parts of long-lasting phosphor powder; 30 parts of borax; 5 parts of glass powder; and 1 part of zinc oxide. The preparation method of the fluorescent ceramic product made from the fluorescent glaze is as follows:

[0036] (1) Mix the components of the raw materials evenly, mix them in the ratio of material: ball: water = 1:2:0.8, put them in a ball mill for ball milling for 4 hours, add water to the mixture after ball milling to make a glaze slurry, and stale for 3.5 hours , get fluorescent glaze;

[0037] (2) Spray the above-mentioned fluorescent glaze on the surface of the glaze-free ceramic product, put it into an electric furnace, calcinate at 900° C., and then cool naturally to obtain the fluorescent ceramic product.

Abstract

The invention belongs to the technical field of ceramic decoration and discloses fluorescent glaze, a fluorescent ceramic product prepared from the same and a method for preparing the product. The fluorescent glaze is prepared from fluorescent powder, borax and a proper amount of glass powder and zinc oxide, wherein the glass powder is obtained by grinding waste colorless ordinary glass. On the one hand, the recycling value of the waste glass is improved, the production cost is reduced, and the economic benefit is increased. On the other hand, the glass has quite stable chemical properties andthermal stability by one-time high-temperature solid phase treatment and is not prone to reaction with other components in the raw materials. Besides, borax can also reduce erosion of other components to the fluorescent powder in a high temperature environment and improves stability of fluorescent glaze.

Description

technical field [0001] The invention belongs to the technical field of ceramic decoration, and relates to a fluorescent glaze, a fluorescent ceramic product made from it and a method for manufacturing the product. Background technique [0002] Light-storing fluorescent materials are materials that can absorb and store light energy when exposed to light sources such as visible light and ultraviolet light, and then slowly release the stored light energy in a dark state to produce fluorescence. Fluorescent glaze combines the advantages of light-storing fluorescent materials and ceramics. It has the characteristics of high luminous efficiency and brightness, long afterglow time, strong decoration, no radioactivity and good glaze quality. It can also be made into interior and exterior wall tiles, arts and crafts, Various ceramic products such as murals and lettering can not only play the role of lighting, marking and decoration, facilitate and beautify people's lives, but also gr...
