The invention relates to a flexible ceramizable silicone rubber thermal insulation composite material and a preparation method thereof. The composite material is a silicone rubber/fiber cloth integralstructure, the silicone rubber is a support structure, and the fiber cloth penetrates through the silicone rubber; the composite material is obtained by stacking and vulcanizing mixed rubber sheets and fiber cloth at intervals, the mixed rubber sheets are obtained by mixing the silicone rubber, and the mixed rubber sheets are prepared from, by mass, 100 parts of the silicone rubber, 20-45 parts of fumed silica, 30-160 parts of ceramic powder, 0-40 parts of a fluxing agent, 6-20 parts of short fibers, 1-15 parts of a structure control agent and 1-4 parts of a vulcanizing agent. The ceramizablesilicone rubber composite material provided by the invention is good in flexibility, high in mechanical property, good in ablation resistance and resistant to high-speed airflow scouring, and can meet the requirements of the fields of aerospace and special fireproof engineering on fireproof, thermal-insulating and ablation-resistant thermal protection performance.
