NOVELTY - Preparing composite reinforcing materials for silicon aerogel, comprises (1) adding silicon carbide powder and aqueous alcohol solution into silicon carbide powder, adding into alcohol aqueous solution, adding dispersing agent, stirring, then mixing uniformly without sedimentation to obtain silicon carbide alcohol aqueous solution, and (2) adding nano titanium dioxide aqueous dispersion, graphene aqueous solution and silicon carbide aqueous solution into a container, quick mixing, adding cetyltrimethyl ammonium bromide, mixing uniformly without sedimentation to obtain final product i.e. composite reinforcing material, where the mass ratio between nano titanium dioxide aqueous dispersion, graphene aqueous solution and silicon carbide aqueous alcohol solution is 1:1-1.5:4-5. USE - The method is useful for preparing composite reinforcing materials for silicon aerogel. ADVANTAGE - The composite reinforcing materials: has improved gas gel strength and brittleness, and increased heat insulation effect.
