Problems solved by technology

Due to the high refractive index of these crystals, it produces a matte effect, which also easily affects the compactness of the glaze and causes the glaze to absorb dirt, which limits its application in the field of sanitary ceramics

Embodiment 1

[0036]The preparation of the silver-gray matte glaze sanitary ceramics in the present embodiment is realized according to the following steps: One, take by weighing 27.8% quartz, 26.7% Changting potassium feldspar, 13.55% calcite, 3.84% dolomite, 3.1% Zhangzhou Kaolin, 10% zirconium silicate, 9.83% aluminum oxide, 3.2% zinc oxide, appropriate amount of sodium carboxymethylcellulose and soda ash are loaded into a ball mill, and water is added for ball milling. Wherein, the quality of sodium carboxymethyl cellulose and soda ash accounts for 0.03% and 1.95% of the total mass of raw materials respectively. Material: Ball: The ratio of water is 1:1.2:0.45~0.5, and the ball milling is completed when the particle size of the slurry is less than 10 μm and the proportion is greater than 60%, so as to obtain a uniform basic glaze slurry; 2. In the basic glaze slurry prepared in step 1 Add 1% silver-gray material (main components: Sn and Sb), continue ball milling until the particle size...

Embodiment 2

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

Embodiment 3

[0040] The difference between this embodiment and Example 1 is that the composition ratios in step one are 28.2% quartz, 26.8% Changting potassium feldspar, 13.55% calcite, 3.9% dolomite, 3.21% Zhangzhou kaolin, 10% zirconium silicate , 9.93% aluminum oxide, 3.3% zinc oxide. The quality of sodium carboxymethylcellulose and soda ash accounts for 0.03% and 1.14% of the total mass of raw materials respectively. The firing temperature in step 3 is 1240° C., and the firing time is 15.5 hours. The CR-10 color difference meter produced by the Japanese KONICA manufacturer was used to measure the L value of the product to be 78.7, a (red value): 0.5, b (yellow value): -1. Adopt KGZ-1A gloss meter to measure the glossiness of the product obtained in this embodiment to be 14.0. 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...
