Embodiment 1

[0049] The preparation method of satin glazed tile comprises the following steps:

[0050] Step 1. Pressing the ceramic base material into a green body;

[0051] Step 2. Dry the green body in a drying kiln, and control the moisture content of the green body within 0.28wt% after drying;

[0052] Step 3. Sprinkle sintered top glaze on the surface of the green body after drying; the chemical composition of the sintered top glaze includes: in terms of mass percentage, loss on ignition: 3.2-4.6%; SiO 2 : 46~49%; Al 2 o 3 : 28~32%; CaO: 1.2~1.8%; MgO: 1.6~2.0%; K 2 O: 5.7~6.2%; Na 2 O: 2.7~3.6%; ZrO 2 : 6.5~7.8%; specific gravity is 1.84~1.88g / cm 3 , the application amount is 450~480g / m 2 ;

[0053] Step 4. Ink-jet printing design patterns on the surface of the glazed body;

[0054] Step 5. Perform electric drying on the body after inkjet printing design pattern, the drying temperature is 240°C, and the drying time is 80 seconds;

[0055] Step 6. Drizzle satin glaze on the...

Embodiment 2

[0064] Basically the same as Example 1, the difference is that the raw material composition of the satin glaze includes: in parts by mass, 32 parts of potassium feldspar, 8 parts of kaolin, 2 parts of corundum, 7 parts of calcite, 13 parts of calcite, and 6 parts of calcined zinc oxide. Parts, 9 parts of barium carbonate, 23 parts of high-temperature matte frit. The specific gravity of the satin glaze is 1.86g / cm 3 , the application amount is 220g / m 2 .

[0065] The surface glossiness of the obtained satin glazed tile is 10 degrees. The abrasion resistance of the obtained satin glazed tile is grade 4, 2100 revolutions. The antiskid coefficient u of the obtained satin glazed tile is greater than 0.8.

Embodiment 3

[0067] Basically the same as Example 1, the difference is that the raw material composition of the satin glaze includes: in parts by mass, 34 parts of potassium feldspar, 6 parts of kaolin, 3 parts of corundum, 5 parts of calcite, 12 parts of calcined talc, 7 parts of calcined zinc oxide Parts, 8 parts of barium carbonate, 25 parts of high-temperature matte frit.

[0068] The surface glossiness of the obtained satin glazed tile is 6 degrees. The abrasion resistance of the obtained satin glazed tile is grade 4, 2100 revolutions. The antiskid coefficient u of the obtained satin glazed tile is greater than 0.8.

Abstract

The invention discloses satin glaze, a satin glazed tile and a preparation method of the satin glazed tile. The satin glaze comprises the following chemical components in percentage by mass: 43-48% of SiO2; 14-17% of Al2O3; 16-21% of alkaline earth metal oxide; 6.1-7.2% of an alkali metal oxide; 5.2-6.6% of ZnO; and 1.2-1.5% of ZrO2. According to the satin glaze, the high-temperature matte frit and the raw glaze are combined for use, so that the requirements of luster, hand feeling, transparency, wear resistance, glaze texture and the like of the satin glaze are better met. The satin glazed tile solves the problems of low glaze glossiness and poor transparency, and hardly has glaze defects; besides, the luster of the satin glaze surface is not influenced by kiln temperature or raw material fluctuation, and the luster of the glaze surface is stable.

Description

technical field [0001] The invention belongs to the field of ceramic building materials, and in particular relates to a satin glaze, a satin glazed tile and a preparation method thereof. Background technique [0002] Satin glazed tiles can restore the natural luster of the real stone surface and provide a comfortable and soft visual effect. At present, most of the popular satin glazes in the market are obtained by debugging raw glazes. The stability of raw glazes is poor, and high content of silicon and aluminum cannot be introduced to avoid opacification, which leads to the glaze gloss of satin glazed tiles basically at 10 Above the degree, the glaze is not wear-resistant and has many defects. Therefore develop a kind of low luster, wear-resisting, satin glazed tile with good glaze quality, is the current technical problem to be solved urgently. Contents of the invention [0003] In view of the above problems, the present invention provides a satin glaze, a satin glazed...
