摘要（英）：

The invention provides an autocatalytic aerogel heat insulation composite material. The aerogel heat insulation composite material consists of fiber material and aerogel, wherein the aerogel is prepared from silicon-based hydrosol and silicon alcohol salt. The invention also provides a method for preparing the aerogel heat insulation composite material with simple process and easy operation. The method comprises the steps of composite sol preparation, impregnation and jelling, ageing, supercritical drying treatment and the like. The aerogel heat insulation composite material has the advantages of high temperature resistance, controllable structure and performance, simple and convenient process and the like, can be applied in the civil heat insulation field, and can meet the special requirements of aviation, spaceflight or military affairs and the like.
