The invention discloses a quick-drying repair refractory material, which is composed of the following raw materials by weight part: 10-20 of celestite, 10-20 of expanded perlite, 3-4 of terpene resin, 30-40 of high aluminium bauxite, 20-30 of corundum, 0.3-1 of propenol, 0.3-0.5 of royal jelly, 10-16 of flax fiber, 2-3 of glacial acetic acid, 26-30 of tetraethyl orthosilicate, 80-102 of 6-10% ammonia water, 100-110 of 3-5% hydrogen peroxide, 1-2 of sodium molybdate, and 0.1-0.3 of diethanolamine. The tetraethyl orthosilicate involved in the invention is hydrolyzed into silanol sol under the condition of adding the catalyst glacial acetic acid, the silanol sol is mixed with a fiber activation solution, and by evaporation of the solvent, a heterocomplex containing carbon and silicon can be obtained, and finally high temperature carbonization is carried out, and the carbon source is provided by the fiber activation solution, thus obtaining a carbon silicon composite additive. The carbon silicon composite additive has the advantages of stable chemical properties, high heat conductivity coefficient, small thermal expansion coefficient, thermal shock resistance, light weight, and high strength.
