Problems solved by technology

[0003] Traditional glazes tend to produce air bubbles and uneven glazing during use, which leads to the surface of ceramic products not smooth enough, easy to stain, and difficult to clean; also the glaze has low sintering hardness and is easy to scratch during use, which further leads to its Poor stain resistance and wear resistance, not stable performance

Abstract

The invention relates to the technical field of ceramic glaze production, and provides a ceramic glaze with stable performance and a preparation method thereof. The ceramic glaze is prepared from 10-18 parts of quartz, 10-18 parts of Zuoyun soil, 5-15 parts of frit, 3-10 parts of modified nano silicon dioxide compounded graphene oxide, 3-10 parts of boric acid, 3-10 parts of zirconium silicate, 2-6 parts of calcite, 2-6 parts of strontium titanate, 2-6 parts of barium carbonate, 0.5-3 parts of ammonium dihydrogen phosphate, 0.5-3 parts of zinc oxide and 0.5-3 parts of fluorine-containing auxiliaries. The preparation method comprises the following steps: S1, preparing modified nano silicon dioxide compounded graphene oxide; S2, crushing and sieving; and S3, preparing slurry. The hardness and wear resistance of the glaze can be greatly improved, the glaze layer is compact in structure and can fill pores in the surface of a ceramic matrix, the stain resistance and cold resistance of a ceramic product are improved, and the obtained glaze is high in quality, stable in performance and long in service life.

Description

technical field [0001] The invention relates to the technical field of ceramic glaze production, in particular to a ceramic glaze with stable performance and a preparation method thereof. Background technique [0002] Glaze refers to a glassy thin layer covering the ceramic body, but its composition is more complex than glass, and its properties and microstructure are also quite different from glass. For example, its high temperature viscosity is much greater than that of glass, and its composition and The preparation process is similar to the blank and different from glass. The function of glaze is to improve the surface properties of ceramic products, make the surface of the product smooth, impermeable to liquid and gas, and not easy to be stained. Secondly, it can improve the mechanical strength and electrical properties of the product. Performance, chemical stability and thermal stability. Glaze also plays a decorative role on the body. It can cover the bad color and rou...
