Example Embodiment

[0035] Example 1

[0036] The preparation of the silver-gray matt glaze sanitary ceramics in this example is realized according to the following steps: 1. Weigh 27.8% quartz, 26.7% potash feldspar, 13.55% calcite, 3.84% dolomite, and 3.1% Zhangzhou in proportion. Kaolin, 10% zirconium silicate, 9.83% aluminum oxide, 3.2% zinc oxide, and an appropriate amount of sodium carboxymethyl cellulose and soda ash are charged into a ball mill, and water is added for ball milling. Among them, the masses of sodium carboxymethyl cellulose and soda ash accounted for 0.03% and 1.95% of the total mass of raw materials, respectively. The ratio of material: ball: water is 1:1.2:0.45~0.5, and the slurry particle size is ball milled to less than 10μm, and the proportion is greater than 60%. The ball milling is completed, and a uniform basic glaze slurry is obtained; 2. In the basic glaze slurry prepared in step one Add 1% silver-gray material (main ingredients: Sn and Sb), continue ball milling unt...

[0037] Example 2

[0038] The difference between this embodiment and embodiment 1 is that the composition ratios in step 1 are respectively 27.8% quartz, 26.7% changting potassium feldspar, 14.55% calcite, 3.83% dolomite, 3% Zhangzhou kaolin, and 10% zirconium silicate. , 9.83% alumina, 3.2% zinc oxide. The mass of sodium carboxymethyl cellulose and soda ash accounted for 0.03% and 1.06% of the total mass of raw materials, respectively. The firing temperature in step three is 1220°C, and the firing time is 15h. The L value of this product is 75.1, a (red value): 0.3, b (yellow value): -0.5 measured by CR-10 color difference meter produced by Japanese KONICA manufacturer. The gloss of the product obtained in this example measured with a KGZ-1A gloss meter was 10.6. The other steps and parameters are the same as in Example 1.

[0039] Example 3

[0040] The difference between this embodiment and embodiment 1 is that the composition ratios in step 1 are 28.2% quartz, 26.8% changting potassium feldspar, 13.55% calcite, 3.9% dolomite, 3.21% Zhangzhou kaolin, and 10% zirconium silicate. , 9.93% alumina, 3.3% zinc oxide. The masses of sodium carboxymethyl cellulose and soda ash accounted for 0.03% and 1.14% of the total mass of raw materials, respectively. The firing temperature in step three is 1240°C, and the firing time is 15.5h. The L value of this product is 78.7, a (red value): 0.5, b (yellow value): -1 measured by CR-10 color difference meter produced by Japanese KONICA manufacturer. The gloss of the product obtained in this example is 14.0 measured with a KGZ-1A gloss meter. The other steps and parameters are the same as in Example 1.

Abstract

The invention discloses a preparation method of matte glaze sanitary ceramic. The preparation method comprises the steps of carrying out ball milling on 27.8%-29% of quartz, 25.5%-26.9% of Changding potassium feldspar, 13.55%-15.5% of calcite, 3.83%-4.3% of dolomite, 3%-3.3% of Zhangzhou kaolin, 9%-10.1% of zirconium silicate, 9.83%-10.1% of aluminum oxide, 3.2%-3.4% of zinc oxide, 0.03%-0.04% of sodium carboxymethylcellulose and 1.06%-1.95% of sodium carbonate until the particle size of slurry is smaller than 10 microns and the ratio is 60%-65%, adding ceramic pigments, continuing to carry out ball milling until the particle size of slurry is smaller than 10 microns and the ratio is 69%-71%, sieving by virtue of a 180-mesh sieve so as to obtain uniform sanitary ceramic matte glaze slurry, spraying the sanitary ceramic matte glaze slurry to the surface of a sanitary ceramic blank, adequately drying, firing in a tunnel kiln at 1200-1250 DEG C for 15-18 hours, and cooling, so as to obtain the matte glaze sanitary ceramic product. The prepared matte glaze sanitary ceramic has a special matte effect and pure colors and is rich in aesthetic perception, and the problem of poor sewage resistance of traditional matte glaze is further overcome.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a method for preparing matte glazed sanitary ceramics. Background technique [0002] In today's society, the continuous development of my country's real estate industry closely revolves around the huge market demand for sanitary ceramics associated with real estate. With the rapid development of China's ceramic production technology and technology, personalized products in the sanitary ware market are prominent, and product development has begun to tend to mid-range and high-end. With the improvement of consumers' personal income and appreciation taste, the demand for mid-to-high-end sanitary ceramic products continues to expand. In addition, with the improvement of infrastructure and the increasing investment in residential housing construction, with the steady growth of GDP, the income of ordinary people is also increasing, and they are beginning to pay attention to bathroom decoration...
