High-temperature-resistant ceramic composite material as well as preparation method and application thereof
The invention discloses a high-temperature-resistant ceramic composite material as well as a preparation method and application thereof. The method comprises the following steps: (1) mixing aluminosilicate rock-forming minerals containing calcium, sodium and potassium with mullite, aluminum silicate fibers, spodumene, silicon dioxide, zirconium diboride, aluminum oxide, silicon powder, calcium oxide and aluminosilicate clay to form coarse mixed slurry; (2) mixing graphene powder and sodium humate into the coarse mixed slurry to prepare a ball-milled material A; (3) mixing polyacrylamide, polyvinyl alcohol and carboxymethyl cellulose into the ball-milled material A to prepare a ball-milled material B; (4) discharging and sieving the ball-milled material B to prepare a mixed material; (5) standing and precipitating the mixed material, conducting filtering, adding obtained materials into a filter press, and carrying out filter pressing treatment, so as to obtain a ceramic blank; and (6) molding the ceramic blank into a ceramic blank, and then sending the ceramic blank into a kiln for firing, so as to obtain the high-temperature-resistant ceramic composite material. The scheme is reliable to implement, and the high-temperature-resistant performance of a product is good.
