Abstract

The invention provides a high-performance aerogel composite material, and a preparation method and equipment of the high-performance aerogel composite. The aerogel composite material comprises a silicon dioxide aerogel and a fiber material, wherein the silicon dioxide aerogel uses tetramethyl orthosilicate and water as raw materials and an alcohol solvent as a solvent to prepare a silica sol, and no gel catalyst is added in the silica sol. The equipment comprises a reaction part and a circulated cooling part. The method comprises the steps of preparing the sol, dipping glue, standing, gelatinizing, aging gel, dewatering, drying and the like. With the adoption of the method, materials with planar or abnormal shapes and multiple sizes can be conveniently and selectively prepared, the gelation time is controllable, no catalyst is needed, the kinds of raw materials are few, the operation is simple and convenient, and the environmental pollution is low. The material is excellent in heat-insulating property and has a wide application prospect in the fields of the civil industry, the space flight and aviation industry and the military industry.
