Preparation method of silicon carbide aerogel thermal insulation material
The invention relates to a preparation method of a silicon carbide aerogel thermal insulation material, and belongs to the technical field of thermal insulation materials. The preparation method of the silicon carbide aerogel thermal insulation material comprises preparation of a silicon carbide aerogel reinforced fiber material and an integral compounding process of the material. The preparation method comprises the steps of soaking a carbon fiber material in silica sol dissolved with silicon carbide, gelling, aging and drying to obtain a silicon carbide aerogel reinforced fiber material, and carrying out composite molding on the reinforced material to obtain the aerogel thermal insulation material. By applying the silicon carbide aerogel to the carbon fiber thermal insulation material, the carbon fiber thermal insulation material has the advantages of large specific surface area, low heat conductivity coefficient, small density and the like, and the preparation method is simple and easy for industrial mass production.
