The invention discloses a novel nanometer refractory material. The novel nanometer refractory material comprises, by weight, 10-13 parts of nanometer quartz sand, 20-37 parts of nanometer silica, 0.4-1 part of lithium silicate, 50-60 parts of nanometer alumina, 1-2 parts of calcium hydrogen phosphate, 2-2.5 parts of stearamide, 10-16 parts of flax fibers, 2-3 parts of glacial acetic acid, 26-30 parts of ethyl orthosilicate, 80-102 parts of ammoniacal liquor with content of 6-10%, 100-110 parts of hydrogen peroxide with content of 3-5%, 0.7-1 part of palm wax, 4-6 parts of terpene resin and 0.1-0.2 parts of lauryl mercaptan. Ethyl orthosilicate is hydrolyzed to form silanol sol in the presence of a glacial acetic acid catalyst, the silanol sol and a fiber activation solution are mixed, the solvent is evaporated so that a carbon-silicon compound is obtained, and the carbon-silicon compound is carbonized at a high temperature so that the carbon-silicon compound assistant is obtained, wherein the fiber activation solution provides a carbon source. The carbon-silicon compound assistant has the advantages of stable chemical performances, high heat conduction coefficient, small coefficient of thermal expansion, thermal shock resistance, light weight and high strength.
