Abstract

The invention relates to a preparation method of a yttrium zirconate microcrystal ceramic glaze having a photocatalytic function. The preparation method comprises the following steps: preparing quartz, potash feldspar, albite, borax, Y2O3, Suzhou clay and lithium carbonate, keeping the above raw materialsat 1270-1290 DEG C for 20-40 minutes, taking out, pouring into water, quenching to prepare a fusion cake, and grinding the fusion cake to obtain a material A; preparing the material A, Y2O3, ZrO2 and Suzhou clay to obtain a material B; adding the material B and dispersing agent into water, and uniformly stirring and mixing to prepare a glaze slip; and applying the glaze slip to the surface of ceramics, and firing to obtain the yttrium zirconate microcrystal ceramic glaze having a photocatalytic function. According to the invention, the ceramic glaze is prepared through a firing process and does not need coating, so that the prepared functional ceramic glaze material can be tightly combined with a ceramic matrix; and the photocatalyst Y2Zr2O7 generated in the sintering process of Y2O3 and ZrO2 is uniformly distributed in the glaze material, thereby avoiding the condition that the aesthetic property of the glaze material is influenced due to a rainbow effect.

Description

technical field

[0001] The invention belongs to the technical field of ceramic glazes, and in particular relates to a preparation method of yttrium zirconate microcrystalline ceramic glaze with photocatalytic function, which is applied in the fields of architectural sanitary ceramics and daily-use ceramics. Background technique

[0002] With the development of modern society, in the process of rapid urbanization, social contradictions and environmental problems have gradually become prominent, especially in recent years, air quality has been criticized by the whole people [Guo Shihong, Gao Ming, et al. Coordination of air quality and urbanization quality Relationship Research [J]. Ecological Economy, 2015, 31(3):25-30.]. We know that in the home environment that is closely related to people's lives, the main air pollutants include volatile organic compounds, air colonies, CO 2 [Zhuang Xiaomin. Analysis of indoor air pollution and research on the release of typical pollutant...
