preparation example Construction

[0033] A preparation process of crystalline glaze antique brick, comprising the following steps:

[0034] 1) Preparation of crystal-based glaze: mix the raw materials of crystal-based glaze in proportion; add binder and debonding agent, mix well to obtain a mixture; add water to the mixture, ball mill it into a glaze slurry, and obtain a crystal-based glaze;

[0035] 2) Preparation of the crystallization agent: mix the raw materials of the crystallization agent in proportion, burn them into a frit, and break the frit to obtain the crystallization agent;

[0036] 3) Glazing: apply the crystalline base glaze on the surface of the brick, and then apply the crystallization agent on the crystalline base glaze;

[0037] 4) Firing: firing in a kiln, firing at 1150-1230°C for 50-60 minutes, to obtain crystal glazed antique bricks with crystal flower artistic effect;

[0038] Wherein, the glaze used is the above-mentioned glaze.

[0039] Preferably, the amount of the binder is 0.2-0....

Abstract

The invention discloses a glaze material of a high temperature fast firing crystal glaze archaized brick and preparation process thereof. Raw material types of crystal glaze are few and wide in sources. A preparation method of the crystal glaze archaized brick is simple, traditional crystal glaze complex process and specific firing rules are broken through, the crystal glaze archaized brick can be obtained through once firing, operability is good, energy is saved, environment is protected, and firing cost is reduced. By adjusting proportion of glaze material components and colorants and the process method, crystal glaze with different colors and crystal flowers in different sizes are obtained through firing, glaze is light, a few needle holes exist occasionally, and firing yield reaches more than 92%.

Description

technical field [0001] The invention belongs to the field of crystalline glaze, in particular to a high-temperature fast-fired crystalline glaze antique brick glaze and a preparation process. Background technique [0002] Crystalline glaze is a highly decorative artistic glaze, which enjoys a wide reputation for its unique artistic style and is quite favored by consumers. In recent years, many ceramic production areas in my country have successfully carried out trial production of crystalline glazes, and widely tested crystalline glaze decorations on display porcelain, daily utensils, and wall and floor tiles, and achieved gratifying results. However, at present, the development of archaic tiles with crystalline glaze is still rare. The main reason is that the traditional crystalline glaze has defects such as complex process conditions and high costs, which limit its commercial production. [0003] The crystallization range of crystalline glaze is very narrow, and the firin...
