[0022] 1) Preparation of ceramic blank:
[0023] a. Weighing: 40-55 parts of kaolin, 10-15 parts of feldspar, 25-28 parts of quartz, 15-22 parts of chaff ash, 1.5-1.8 parts of black mud, 1.2-1.6 parts of dolomite, and the ceramic blank Particles are sieved with a 60-mesh sieve; b. ball milling the raw material powder, solvent and modifying additives to obtain a slurry; c. uniformly coating the slurry on the surface of the ceramic blank particles in step a to obtain Coating the ceramic raw material particles; d. placing the coated ceramic raw material particles in a closed space for aging for 24-48 hours;
[0024] 2) Preparation of ceramic glaze:
[0025] a. Weigh each component raw material: SiO2 51-53 parts, A1203 7-9 parts, CaO 12-15 parts, MgO 22-28 parts, Na2O 2-3 parts, calcium hydrogen phosphate 15-18 parts, ZnO 3- 5 parts, 0.2-0.35 parts of ZrO, 0.2-0.5 parts of sodium hydroxymethyl cellulose, 26-32 parts of FeSO4; b. sieve through a 60-mesh sieve to obtain ceramic gl...
Embodiment 1
[0030] Embodiment 1: the formula of each material used in the present invention is: the composition of ceramic glaze and its mass composition are: SiO2 53 parts, A1203 7 parts, CaO 15 parts, MgO 25 parts, Na2O 3 parts, calcium hydrogen phosphate 16 parts, 3 parts of ZnO, 0.28 parts of ZrO, 0.32 parts of sodium hydroxymethylcellulose, 28 parts of FeSO4; the composition and mass parts of the ceramic blank are: 50 parts of kaolin, 12 parts of feldspar, 25 parts of quartz, chaff ash 17 parts, 1.5 parts of black mud, 1.6 parts of dolomite; 27 parts of thickener; 1 part of water reducer. The water reducer uses sodium trimetaphosphate, the thickener is a mixture of diatomite and ethylene glycol, and the mass ratio of diatomite to ethylene glycol is 3:1. The specific process is the same as above, the modulus of rupture of the prepared ceramic product is as high as 88.6 MPa, and the Mohs hardness of the ceramic can reach 5.
Embodiment 2
[0031] Embodiment 2: The composition of ceramic glaze and its mass composition are: SiO2 52 parts, A1203 8 parts, CaO 14 parts, MgO25 parts, Na2O2 parts, calcium hydrogen phosphate 17 parts, ZnO4 parts, ZrO0.3 part, methylol 0.2 parts of sodium cellulose, 30 parts of FeSO4; the composition and mass parts of the ceramic blank are: 45 parts of kaolin, 12 parts of feldspar, 27 parts of quartz, 18 parts of chaff ash, 1.8 parts of black mud, 1.4 parts of dolomite parts; 30 parts of thickener; 0.9 parts of water reducer. The water reducer uses a mixture of sodium trimerium metaphosphate and sodium humate with a mass ratio of 1:3, and the thickener uses diatomite and ethylene glycol with a mass ratio of 4:1, and is processed according to the above-mentioned process. Ceramic products have good wear resistance, the modulus of rupture is as high as 92.4MPa, and the Mohs hardness of ceramics can reach 6-7.
