[0018] An impact-resistant, high-strength daily-use ceramic, the parts by weight of each component of the raw material are:

[0019] 45 parts of Yunnan kaolin, 25 parts of Guangxi kaolin, 18 parts of potassium feldspar, 5 parts of spodumene, 10 parts of wollastonite powder, 0.1 part of cobalt oxide, 0.3 part of magnesium oxide, and 0.1 part of titanium dioxide.

[0020] Its preparation method comprises the following steps:

[0021] Separately pulverize the removed raw materials, mix, coarsely grind, pass through a 6-mesh sieve, make pulp, wet ball mill for 50 minutes, pass through a 200-mesh sieve, press filter, and stale at room temperature for 8 days to obtain the finished mud; roll the finished mud into shape Make the green body; burn the green body at 300°C for 3 hours, then burn it at 1000°C for 8 hours after cooling, and polish and plane after cooling to room temperature to get the product.

Embodiment 2

[0023] An impact-resistant, high-strength daily-use ceramic, the parts by weight of each component of the raw material are:

[0024] 55 parts of Yunnan kaolin, 35 parts of Guangxi kaolin, 25 parts of potassium feldspar, 10 parts of spodumene, 15 parts of wollastonite powder, 0.5 parts of cobalt oxide, 0.5 parts of magnesium oxide, and 0.5 parts of titanium dioxide.

[0025] Its preparation method comprises the following steps:

[0026] The raw materials after de-impurity were crushed separately, mixed, roughly ground, passed through a 12-mesh sieve, pulped, wet ball milled for 75 minutes, passed through a 300-mesh sieve, press-filtered, aged at room temperature for 20 days, and the finished mud was obtained; the finished mud was rolled into shape Make the green body; burn the green body at 350°C for 5 hours, then burn it at 1100°C for 8.5 hours after cooling, and polish and planed after cooling to room temperature to get the product.

Embodiment 3

[0028] An impact-resistant, high-strength daily-use ceramic, the parts by weight of each component of the raw material are:

[0029] 50 parts of Yunnan kaolin, 30 parts of Guangxi kaolin, 21 parts of potassium feldspar, 7.5 parts of spodumene, 12.5 parts of wollastonite powder, 0.3 parts of cobalt oxide, 0.4 parts of magnesium oxide, and 0.3 parts of titanium dioxide.

[0030] Its preparation method comprises the following steps:

[0031] The raw materials after de-impurity were crushed separately, mixed, coarsely ground, passed through a 9-mesh sieve, pulped, wet ball milled for 60 minutes, passed through a 250-mesh sieve, press-filtered, aged at room temperature for 14 days, and the finished mud was obtained; the finished mud was rolled into shape The green body is made; the green body is fired at 320°C for 4 hours, then fired at 1050°C for 8.2 hours after cooling, polished and planed after cooling to room temperature, and the product is obtained.

Abstract

The invention relates to an impact-resistant and high-strength domestic ceramic glaze, and belongs to the technical field of domestic ceramics. The impact-resistant and high-strength domestic ceramic glaze comprises the following components in parts by weight: 45 to 55 parts of Yunnan kaolin, 25 to 35 parts of Guangxi kaolin, 18 to 25 parts of potassium feldspar, 5 to 10 parts of spodumene, 10 to 15 parts of wollastonite powder, 0.1 to 0.5 part of cobalt oxide, 0.3 to 0.5 part of magnesium oxide, and 0.1 to 0.5 part of titanium dioxide. The preparation method comprises the following steps: allowing raw materials from which impurities are removed to be subjected to crushing, mixing and coarse grinding, sieving through a 6 to 12-mesh sieve, slurrying, performing wet ball-milling for 50 to 75 minutes, sieving through a 200 to 300-mesh sieve, filter pressing, ageing for 8 to 20 days at room temperature to obtain finished product mud; rolling the finished product mud to be molded to obtain a green body; and firing the green body for 3 to 5 hours at a temperature of 300 to 350 DEG C, cooling and then firing for 8 to 8.5 hours at a temperature of 1000 to 1100 DEG C, polishing after cooling to room temperature to obtain the product. The domestic ceramic has good thermal stability and stable chemical properties, is light and delicate, and has the characteristics of impact resistance and high strength.

Description

technical field [0001] The invention relates to a daily-use ceramic, in particular to an impact-resistant, high-strength daily-use ceramic, which belongs to the technical field of daily-use ceramics. Background technique [0002] Daily-use ceramics refer to porcelain for daily use. As the name suggests, the production of daily-use ceramics can be said to be due to people's needs for daily life. In daily life, people have the most contact with and are also most familiar with porcelain, such as tableware, tea sets, coffee sets, wine sets, and tableware. People's lives are closely related. [0003] Daily-use ceramics have the following advantages: first, it is easy to wash and keep clean; second, it has good thermal stability, slow heat transfer, and is not easy to burst when subjected to rapid heat and sudden cooling changes of a certain temperature difference, and it is used to hold boiling water. Or hot food, it is not too hot when you hold it; third, the chemical properti...
