Problems solved by technology

[0002] The actual situation of the production of architectural ceramics is going to two poles: one is firing at low temperature, which is conducive to energy saving, but the overall quality of its products is not ideal; surface texture
The wear resistance of the glaze surface, its thermal stability, etc.) are much better than the previous one; but because the commonly used flash glaze can only be used at medium and low temperatures, it is used at high temperature, especially for one-time firing, flash It quickly deteriorates and disappears, and the glaze surface is also blistered, which cannot play a decorative effect; therefore, there is an urgent need for a flash that can be used at high temperature, especially at a high temperature for one firing, and can have a good decorative effect on the ceramic glaze surface. glaze

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with specific embodiments.

[0021] The process flow is as follows: raw material entering the factory, inspection, batching, melting, water quenching, inspection, ball milling, inspection, drying, milling, inspection, packaging. According to the following mass percentage ingredients: Al 2 o 3 1~16%, SiO 2 50~75%, CaO 0.5~5%, MgO 0~2%, K 2 O 2~9%, Na 2 O 0~2%, ZnO 2~16%, PbO 0~2%, ZrO 2 3~9%, CeO 2 3~10%, B 2 o 3 0.5~8%. The melting temperature is 1550-1600°C. The fineness of the ball-milled glaze slurry is less than 0.3% (remainder of 325 mesh sieve). The glaze slurry must be dried after the ball milling, and the drying temperature is 150-250°C. The milling parameters are as follows: pulverize through a 250-mesh sieve, and the fineness is <0.3% (325 mesh).

[0022] Experiments were carried out according to the parameters in Table 1, and the results showed that the flash glaze...

Abstract

The invention discloses a high-temperature glisten glaze and a preparation method thereof. The glaze comprises, by mass, 1-16% of Al2O3, 50-75% of SiO2, 0.5-5% of CaO, 0-2% of MgO, 2-9% of K2O, 0-2% of Na2O, 2-16% of ZnO, 0-2% of PbO, 3-9% of ZrO2, 3-10% of CeO2 and 0.5-8% of B2O3. The glisten glaze is wide in application range, good in firing performance and high in stability and glisten strength; and the preparation method is reasonable and simple in technology.

Description

technical field [0001] The invention belongs to the field of decorative powder for ceramics, and in particular relates to a high-temperature flash glaze and a manufacturing method thereof. Background technique [0002] The actual situation of the production of architectural ceramics is going to two poles: one is firing at low temperature, which is conducive to energy saving, but the overall quality of its products is not ideal; Surface texture. The wear resistance of the glaze surface, its thermal stability, etc.) are much better than the previous one; but because the commonly used flash glazes can only be used at medium and low temperatures, they are used at high temperatures, especially for one-time firing. The flash will quickly deteriorate and disappear, and the glaze surface will also blister, which will not have a decorative effect; therefore, there is an urgent need for a ceramic glaze that can be used at high temperatures, especially at high temperatures for one firi...
