Embodiment 1

[0039] In parts by mass, 7 parts of barium carbonate, 7 parts of zirconium silicate, 46 parts of albite, 7 parts of calcined talc, 12 parts of calcium carbonate, 9 parts of aluminum hydroxide, 7 parts of kaolin, 5 parts of titanium dioxide and 0.3 parts Sodium tripolyphosphate and 0.3 parts of carboxymethyl cellulose, mix, add 70 parts of water, and then ball mill according to the mass ratio, ball: material: water = 1:1.5:0.7 until the fineness of glaze slurry: 325 mesh Sieve the remaining 0.3%~0.4%, and then age for 24 hours to get satin glaze.

[0040] The satin glaze material obtained by this method is passed through the glaze process according to the specific gravity of 1.75g / mL and the glaze amount of 500g / m 2 The standard is applied on the ceramic tile body, and then the sample is put into the kiln and fired at 1230°C for 58 minutes to obtain a high-hardness satin glazed ceramic tile product with a Mohs hardness of 6.

Embodiment 2

[0042] In parts by mass, 6 parts of barium carbonate, 6 parts of zirconium silicate, 46 parts of albite, 6 parts of calcined talc, 12 parts of calcium carbonate, 9 parts of aluminum hydroxide, 6 parts of kaolin, 9 parts of titanium dioxide and 0.3 parts Sodium tripolyphosphate and 0.3 parts of carboxymethyl cellulose, mix, add 70 parts of water, and then ball mill according to the mass ratio, ball: material: water = 1:1.5:0.7 until the fineness of glaze slurry: 325 mesh Sieve the remaining 0.3%~0.4%, and then age for 24 hours to get satin glaze.

[0043] The satin glaze material obtained by this method is passed through the glaze process according to the specific gravity of 1.75g / mL and the glaze amount of 500g / m 2 The standard is applied on the ceramic tile body, and then the sample is put into the kiln and fired at 1230°C for 58 minutes to obtain a high-hardness satin glazed ceramic tile product with a Mohs hardness of 6.

Embodiment 3

[0045] In parts by mass, 7 parts of barium carbonate, 7 parts of zirconium silicate, 46 parts of albite, 7 parts of calcined talc, 12 parts of calcium carbonate, 9 parts of aluminum hydroxide, 7 parts of kaolin, 5 parts of titanium dioxide and 0.3 parts Sodium tripolyphosphate and 0.3 parts of carboxymethyl cellulose are mixed, and 70 parts of printing oil are added, and then according to the mass ratio, the ratio of ball:material:printing oil=1:1.5:0.7 is ball milled until the fineness of the glaze slurry: 325 mesh Sieve the remaining 0%, and then age for 24 hours to get satin glaze.

[0046] The satin glaze material obtained by this method is processed by rubber roller or lithographic printing according to the specific gravity of 1.50~1.70g / mL and the glaze amount of 500g / m 2 The standard is applied on the ceramic tile body, and then the sample is put into the kiln and fired at 1230°C for 58 minutes to obtain a high-hardness satin glazed ceramic tile product with a Mohs hard...

Abstract

The invention discloses satin glaze as well as a preparation method and application thereof. The satin glaze is prepared from the following formula components in parts by mass: 5-10 parts of barium carbonate, 5-10 parts of zirconium silicate, 40-50 parts of albite, 5-10 parts of burnt talc, 10-20 parts of calcium carbonate, 5-15 parts of aluminum hydroxide, 5-10 parts of kaolin, 5-15 parts of titanium dioxide and 0.1-5 parts of additives. By adding the materials such as the titanium dioxide, a great deal of high hardness crystals are precipitated out from the chemical components of the satin glaze after high-temperature firing, and the mohs hardness of the formed overglazed surface is increased to grade 5; furthermore, the satin glaze is enabled to have glaze effects of being smooth, flatand fine, and the problems that in the prior art, the satin glaze is softer in texture and low in surface hardness are solved.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to a satin glaze and its preparation method and application. Background technique [0002] The formula system of the popular satin glaze ceramic products in the market is based on silicon aluminum as the skeleton and calcium barium magnesium as the matting agent system. It is prepared by the process of secondary glazing, that is, white high temperature bottom glaze is applied on the green body first. , and then apply the second glazing method of matt transparent glaze, and then do color decoration under the transparent glaze or on the transparent glaze. The surface gloss of this kind of ceramic products is below 15 degrees, the glaze surface is smooth and fine, and the hand feeling is excellent. The glaze effect of its delicate satin glaze mainly precipitates anorthite microcrystals, part of barium feldspar crystal phase and Talc crystal phase is obtained, but the Mo...
