The invention discloses a pressure resistant anti-fracture sliding plate fireproof material. The pressure resistant anti-fracture sliding plate fireproof material comprises raw materials including, by weight, 2-3 parts of calcium hydrophosphate, 40-50 parts of emery powder, 30-51 parts of alumina-magnesia spinel with the particle size being 1-2 mm, 2-3 parts of aluminium dihydrogen phosphate, 5-10 parts of expansible graphite, 0.3-0.5 part of silicone acrylic emulsion, 1-2 parts of triethanolamine oleic soap, 6-8 parts of phenolic resin, 10-12 parts of sisal fiber, 26-30 parts of tetraethoxysilane, 3-4 parts of a 10-13 mol/l saltpeter solution, 2-3 parts of glacial acetic acid, 0.2-0.3 part of polyisobutene and 1-2 parts of hydroxyl silicone oil. The ethyl orthosilicate is hydrolyzed into a silanol solution on the condition that the catalyst glacial acetic acid is added, the silanol solution and a fiber emulsion are mixed, a heterocomplex containing carbon and silicon is obtained by evaporating the solvent, and finally the fiber emulsion provides a carbon source through high temperature carbonization to obtain a carbon-silicon compound additive. The carbon-silicon compound additive is stable in chemical performance, high in heat conductivity coefficient, small in thermal expansion coefficient, resistant to thermal shock, low in weight and high in strength.
