Problems solved by technology

[0004] In view of the problems raised by the background technology, the purpose of the present invention is to propose a matte glaze for sanitary ceramics, which can show a matte effect of silky luster, has fineness, stain resistance, wide firing temperature range, and thermal stability of the glaze. Good performance, which solves the problems of narrow firing temperature range, poor stain resistance, poor thermal stability and high cost of existing matte glazes;
[0005] Another object of the present invention is to propose a method for preparing sanitary ceramics using the matte glaze for sanitary ceramics. The preparation process is simple, and the glazed surface of the product is smooth and flat without pores, which solves the problem of easy occurrence of air bubbles on the glazed surface of existing sanitary ceramics. Problems of pinholes and poor glaze flatness

preparation example Construction

[0048] A preparation method for sanitary ceramics, using the matte glaze for sanitary ceramics, comprising the following steps:

[0049] (1) Green body preparation: add water to the green body raw material to carry out wet ball milling, and make a sanitary ceramic green body by mold grouting;

[0050] (2) Preparation of matte glaze for sanitary ceramics: according to the formula, the raw materials are added to water ball mill, and the glaze slurry after ball milling is subjected to the first iron removal sieving and the second iron removal sieving to obtain matte glaze for sanitary ceramics ;

[0051] (3) Glazing: Spray the matte glaze for sanitary ceramics onto the surface of the sanitary ceramic body by spraying glaze;

[0052] (4) Firing: drying the glazed sanitary ceramic body, and then firing in a kiln to produce a sanitary ceramic.

[0053] By ball milling the basic glaze raw materials and pigments at one time, the ball milling effect can be stabilized, because a large...

[0072]A preparation method for sanitary ceramics, comprising the steps of:

[0073] (1) Green body preparation: add water to the green body raw materials (using the existing conventional green body raw material formula) and carry out wet ball milling. In the slurry obtained by ball milling, the mass of raw materials with a particle size of less than 10 μm accounts for 53% of the total mass of green body raw materials , the sanitary ceramic green body is obtained by mold grouting;

[0074] (2) Preparation of matte glaze for sanitary ceramics: according to the formula in Table 1 (calculated according to parts by weight), add water to the raw materials and perform ball milling in a ball mill, wherein, according to the mass ratio of raw materials: balls: water = 1: 2.3: 0.6 Carry out ball milling, the ball milling time is 12h, the fineness of the glaze slurry obtained by ball milling is 400 mesh sieve 3 , to prepare matte glaze for sanitary ceramics;

[0075] (3) Glazing: the mat...

Abstract

The invention relates to the technical field of sanitary ceramics, in particular to matte glaze for sanitary ceramics and a preparation method of the sanitary ceramics. The ceramic tile is prepared from the following raw materials in parts by weight: 12-15 parts of potassium feldspar, 15-18 parts of quartz powder, 15-25 parts of waste porcelain powder, 14-20 parts of burnt talcum powder, 12-16 parts of wollastonite powder, 8-10 parts of Hunan kaolin, 8-15 parts of high-aluminum stone powder, 0.1-2 parts of calcined zinc oxide and 2-5 parts of dolomite. The silica-alumina ratio of the matte glaze for the sanitary ceramics is 4.8-6.2. The matt glaze for the sanitary ceramics can show a silky and glossy matt effect and has the characteristics of fineness, stain resistance, wide firing temperature range and good glaze heat stability, the preparation method of the sanitary ceramics using the matt glaze for the sanitary ceramics is simple in preparation process, the glaze surface of the product is smooth, flat and free of fine pores, and the glaze surface is smooth and smooth. The problems that bubbles and pinholes are prone to occurring on an existing sanitary ceramic glaze surface, and the flatness of the glaze surface is poor are solved.

Description

technical field [0001] The invention relates to the technical field of sanitary ceramics, in particular to a matte glaze for sanitary ceramics and a preparation method for sanitary ceramics. Background technique [0002] Matte glaze is a kind of matte glaze with silky luster or jade-like luster, and it is a microcrystalline glaze in the matte glaze system. Matte glaze products are high-end products of modern ceramics, and are also the trend of modern ceramic decoration materials. Matte glazes have a quiet and comfortable feeling due to their fine glaze surface and soft reflection. For example, matte glazes are applied on sanitary ware. Used in conjunction with bathroom cabinets and toilet floor tiles, it can effectively improve the comfort of use. [0003] There are two main methods for the preparation of matte glaze products currently on the market: one is to introduce refractory compounds, which cannot be completely melted during the melting process of the glaze and are i...
