A mirror pattern glaze for sanitary ceramics and preparation method thereof

Abstract

The invention discloses a sanitary ceramic mirror pattern glaze and a preparation method thereof. The preparation raw materials include 26-36 parts of quartz, 1-5 parts of alumina, 20-30 parts of potassium feldspar and 3 parts of dolomite in parts by weight. ~6 parts, 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, 3~8 parts of copper oxide part; it obtains the glaze slurry by ball milling and sieving the prepared raw materials, and applies the glaze slurry to the outer surface of the ceramic body. The finally obtained glaze surface has a cloud-like pattern and has a mirror effect. The preparation of the pattern glaze in the present invention only needs a single Different types of glaze, one-time glazing, one-time firing, compared with the existing multiple-firing process of various glazes or multiple glazes, multiple-time glazing, one-time firing process, the process is simple, the preparation is convenient, and manpower is saved Material resources are very conducive to industrial promotion.

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 the ceramic body and produces the visual effect of patterns after firing. In the prior art, there are mainly two methods for preparing pattern glaze. One is to apply a variety of glazes on the ceramic green body and burn it for 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 glazing in multiple layers and then fired at one time. It uses the different melting temperatures and thickness of the glaze layers of various glazes to make the glazes in the firing process. Blending to form patterns requires high requirements for glazing and firing processes. The thickness of various glaze la...

Problems solved by technology

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.
