Abstract

The invention relates to a preparation method of a yttrium zirconate ceramic glaze material 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 temperature at 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, and grinding 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 in a glaze spray manner, and firing to obtain the yttrium zirconate ceramic glaze material 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 yttrium zirconate generated in the sintering process of Y2O3 and ZrO2 is uniformly distributed in the glaze material, thereby avoiding influencing the aesthetic property of the glaze material due to a rainbow effect.

Description

technical field [0001] The invention belongs to the technical field of ceramic glazes. Specifically relates to a preparation method of yttrium zirconate ceramic glaze with photocatalytic function. Background technique [0002] In the 21st century, human society is developing rapidly, and has made great progress in various aspects such as technology and economy. However, the problems of resources and ecology are becoming increasingly prominent, threatening the sustainable development of human society. The birth of photocatalytic technology provides a new way of thinking for us to use solar energy, a clean, cheap and renewable energy. [0003] Photocatalytic technology began in 1972 with the discovery of the Fujishima-Honda effect [Fujishima A., Honda K. Photocatalysis-decomposition of water at the surface of an irradiated semiconductor [J]. Nature, 1972, 238(5385): 37-38.] , which has aroused the great attention of scientific and technological workers on semiconductor phot...
