The invention discloses a quartz powder aluminous fireproof material. The quartz powder aluminous fireproof material is composed of, by weight, the raw materials of four to eight parts of terpene resin, 0.1-0.2 part of poly trimethyl dihydro-quinoline, 0.4-1 part of lauryl mercaptan, 30-47 parts of fused quartz powder, 10-16 parts of magnesium silicate, 30-34 parts of oxidation aluminous corundum, seven to ten parts of zirconium oxide, 10-14 parts of linen fibers, two to three parts of glacial acetic acid, 26-30 parts of tetraethoxysilane, 80-102 parts of six-percent to ten-percent ammonium hydroxide, 100-110 parts of three-percent to five-percent hydrogen peroxide and 0.4-1 part of sodium carbonate. The tetraethoxysilane is hydrolyzed into silanol gel under the condition of adding the catalyst glacial acetic acid, the silanol gel and fiber activate fluid are mixed, heterocomplex with carbon and silicon is obtained through evaporation solvent, finally high temperature carbonization is carried out, the fiber activate fluid provides a carbon source, carbon and silicon compound additive is obtained, and the carbon and silicon compound additive is stable in chemical performance, high in heat conductivity coefficient, small in coefficient of thermal expansion, resistant to heat shocks, light and high in strength.
