Preparation method of low-temperature-resistant glass-fiber-reinforced SiO2 aerogel composite material
The invention provides a preparation method of a low-temperature-resistant glass-fiber-reinforced SiO2 aerogel composite material. According to the preparation method, tetraethyl orthosilicate is adopted as a silicon source; glass fiber is adopted as a reinforcement phase; and modification, solvent displacement and supercritical drying are carried out to obtain the fiber-reinforced SiO2 aerogel composite material. The composite material provided by the invention has the characteristics of low thermal conductivity, good hydrophobicity, large specific surface area, and low-temperature resistance. The preparation process of the material is simple, is capable of continuous production and therefore has good industrial production and application prospects.
