High-temperature-resistant ceramic fiber material

The invention relates to a high-temperature-resistant ceramic fiber material which is prepared from the following raw materials in parts by weight: 6-10 parts of nano calcium carbonate, 2-6 parts of sulfur trioxide, 7-11 parts of polymethyl methacrylate, 2-8 parts of aluminum trioxide, 1-4 parts of calcium dioxide, 2-6 parts of iron oxide, 15-24 parts of aluminum silicate fiber, 2-7 parts of zirconium latex, 4-9 parts of glaze-free waste ceramic cured sand, 1-3 parts of compound stabilizer, 2-5 parts of activated carbon powder, 7-10 parts of nano zirconium dioxide, 6-10 parts of chrome oxide, 2.5-4 parts of polydimethylsiloxane and 6-11 parts of glass fiber. The ceramic fiber material has the advantages of better high-temperature resistance, favorable strength, favorable elasticity and wider application range.
