Sanitary ceramic mirror surface pattern glaze and preparation method thereof

Abstract

The invention discloses a sanitary ceramic mirror surface pattern glaze and a preparation method thereof. The preparation raw materials include, by weight, 26-36 parts of quartz, 1-5 parts of aluminumoxide, 20-30 parts of potassium feldspar, 3-6 parts of dolomite, 5-15 parts of calcite, 3-6 parts of wollastonite, 1-5 parts of zirconium silicate, 1-6 parts of zinc oxide, 5-10 parts of kaolin and 3-8 parts of copper oxide. The preparation method comprises the following steps of: ball-milling and sieving the preparation raw materials to obtain glaze slip, applying the glaze slip to the outer surface of a ceramic green body so as to finally obtain a glaze surface with cloud-shaped pattern and mirror surface effect. The pattern glaze prepared by the method only needs a single glaze material, one-time glazing and one-time firing, and compared with the existing process of performing multiple firing on multiple glaze materials or the process of performing multiple glazing and one-time firingon multiple glaze materials, the process is simple, the preparation is convenient, the manpower and material resources are saved, and the method is very beneficial to industrial popularization.

Description

technical field [0001] The invention relates to a ceramic glaze and a preparation method thereof, in particular to a sanitary ceramic mirror pattern glaze and a preparation method thereof. Background technique [0002] Pattern glaze is a kind of glaze that is attached to the surface of ceramic body and produces the visual effect of pattern after firing. In the prior art, there are mainly two methods for preparing patterned glazes. One is to apply multiple glazes on the ceramic biscuit and fire it many times. The cost is high and the process is complicated. The thickness has a great influence on the glaze pattern; the other is that a variety of glazes are glazed in multiple layers and then fired at one time. It uses the different melting temperatures and thicknesses of the glaze layers of various glazes to make the glaze Blending to form a pattern, which has high requirements for glazing and firing technology, the thickness of various glaze layers and firing temperature will...

In the prior art, there are mainly two methods for preparing patterned glazes. One is to apply multiple glazes on the ceramic biscuit and fire it many times. The cost is high and the process is complicated. The thickness has a great influence on the glaze pattern; the other is that a variety of glazes are glazed in multiple layers and then fired at one time. It uses the different melting temperatures and thicknesses of the glaze layers of various glazes to make the glaze Blending to form a pattern, which has high requirements for glazing and firing technology, the thickness of various glaze layers and firing temperature will affect the glaze pattern, resulting in difficulties in implementation

In addition, the glaze stability of the two preparation methods is poor, and it is difficult to achieve a uniform and consistent pattern effect on the glaze surface.
