Problems solved by technology

[0003] Luminescent ceramics made of long afterglow materials are a popular ceramic product at present. The long afterglow materials and other raw materials are made into glaze water, coated on the ceramic body, and then fired to make luminous ceramics. Through The sintering temperature of the glaze water made of long afterglow materials must be lower than 820°C to achieve the luminous effect of long afterglow materials, but lowering the sintering temperature will easily lead to cracks on the glaze surface of the fired luminous ceramics and reduce the aesthetics of the luminous ceramics. Affect its sales, need further improvement

Abstract

A long afterglow ceramic with no cracks on the glaze surface and its manufacturing process. A long afterglow ceramic with no cracks on the glaze surface, including a body and a glaze. The glaze includes the following raw materials: low-temperature glaze water, aluminate long afterglow material , The low temperature glaze water includes the following raw materials: Australian spodumene, talc, limestone, borax, boric acid, Dehua quartz, scimitite, kaolin, zinc oxide, the thermal expansion coefficient of Australian spodumene and sillimanite composed of raw materials for low temperature glaze water Very small, through the combination of the two, the thermal expansion coefficient of the glaze can be reduced, making the thermal expansion coefficient smaller than that of the green body. When making it, first make a low-temperature glaze water and aluminate long afterglow material, and then calcinate the frit made It can effectively reduce the firing temperature of the glaze, ensure the firing temperature of the glaze is between 790-810°C, and ensure the luminous effect of the long afterglow material in the glaze.

Description

technical field [0001] The invention belongs to the field of long afterglow porcelain preparation, and in particular relates to a long afterglow ceramic with no cracks on the glaze surface and a manufacturing process thereof. Background technique [0002] Long afterglow material, commonly known as luminous powder, is a kind of photoluminescent material. It refers to the material that can continue to emit light for a long time after the light source is turned off after being irradiated by sunlight and long-wave ultraviolet light for a period of time. Long afterglow material As a kind of "green light source material" for energy storage and energy saving, people pay more and more attention to it today when energy is increasingly scarce. Luminous rubber, luminous leather, luminous glass, luminous ceramics, luminous decoration, luminous crafts, etc. [0003] Luminescent ceramics made of long afterglow materials are a popular ceramic product at present. The long afterglow materia...
