| titleOfInvention | Silica-based light ceramic thermal protection material and preparation method and application thereof |
| abstract | the invention relates to a silica-based lightweight ceramic thermal protection material and a preparation method and application thereof. The thermal protection material takes a rigid heat insulation tile as a base body, is compounded with Si-O-C aerogel, and the surface of the thermal protection material is coated with a strengthening coating. The preparation method comprises the following steps: preparing a rigid heat insulation tile matrix and a Si-O-C sol precursor, soaking the rigid heat insulation tile matrix with the Si-O-C sol precursor, sequentially aging, solvent replacement and supercritical drying to obtain a rigid heat insulation tile base Si-O-C aerogel composite material, and coating a surface strengthening coating on the outer surface of the rigid heat insulation tile base Si-O-C aerogel composite material to obtain the silica-based lightweight ceramic thermal protection material. The material prepared by the invention has the characteristics of low density, high compressive strength, low ablation rate, low thermal conductivity, high emissivity, good heat insulation effect, excellent airflow scouring resistance and the like, and can be used as an outer surface thermal protection material of an outer space exploration aircraft. |
