NOVELTY - Method for preparing high-temperature resistant ceramic composite material, involves (i) coarsely crushing aluminosilicate rock-forming minerals containing calcium, sodium and potassium, mixing with coarsely ground mullite, aluminum silicate fiber, spodumene, silica, zirconium diboride, alumina, silica fume, calcium oxide and aluminosilicate clay, adding to a wet ball mill, and ball-milling to prepare a coarse mixed slurry, (ii) dispersing graphene powder and sodium humate in water to prepare dispersion (A), mixing dispersion (A) in coarse mixed slurry, and ball-milling, (iii) dispersing polyacrylamide, polyvinyl alcohol and carboxymethyl cellulose in water, mixing dispersion (B) in ball abrasive (A), and ball-milling to obtain a ball abrasive (B), (iv) sieving ball abrasive (B), (v) subjecting mixture to static precipitation, filtering, and adding to a filter press for filter press treatment to obtain a ceramic blank, and (vi) molding ceramic blank, air-drying, and sintering. USE - The method is used for preparing high-temperature resistant ceramic composite material for high temperature resistant ceramic product (all claimed). ADVANTAGE - The product has excellent high temperature resistance. DETAILED DESCRIPTION - Method for preparing high-temperature resistant ceramic composite material, involves (i) coarsely crushing aluminosilicate rock-forming minerals containing calcium, sodium and potassium, mixing with coarsely ground mullite, aluminum silicate fiber, spodumene, silica, zirconium diboride, alumina, silica fume, calcium oxide and aluminosilicate clay, adding to a wet ball mill, and ball-milling with water for 1-1.5 hours to prepare a coarse mixed slurry with a solid content of 30-40%, (ii) dispersing graphene powder and sodium humate in water to prepare dispersion (A), mixing the dispersion (A) in the coarse mixed slurry, continuously adding water to adjust the material in the wet ball mill to a slurry with a solid content of 25-35%, and continuously ball-milling and mixing for 2.5-3 hours to obtain ball abrasive (A), (iii) dispersing polyacrylamide, polyvinyl alcohol and carboxymethyl cellulose in water to prepare a dispersion (B), mixing dispersion (B) in ball abrasive (A), continuously adding water to adjust the material in the wet ball mill to a slurry with a solid content of 22-30%, and continuously ball-milling and mixing for 0.5-1 hour to obtain a ball abrasive (B), (iv) discharging and sieving the ball abrasive (B) to obtain a mixture with a particle size of 160-200 mesh, (v) subjecting the mixture material to static precipitation treatment, filtering the precipitate, and adding to a filter press for filter press treatment to obtain a ceramic blank with a water content of 32-35%, and (vi) molding the ceramic blank to a ceramic body, air-drying the ceramic body without deformation, taking the ceramic body out of the mold, sending to a kiln, and sintering at 850-1300 degrees C for 8-10 hours to obtain the high-temperature resistant ceramic composite material.
