Impact-resistant and high-strength domestic ceramic glaze
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.
