Preparation method of silicon dioxide aerogel composite material for low-temperature cold insulation
The invention relates to a preparation method of a silicon dioxide aerogel composite material for low-temperature cold insulation. The preparation method comprises the following specific steps: with tetraethyl orthosilicate as a silicon source and basaltfibers as an enhancement phase, and performing modification, solvent replacement and supercriticaldrying to obtain the fiber enhanced SiO2 aerogel composite material. The material has excellent hydrophobic property, good cold insulation property and low thermal conductivity at a normal temperature and a low temperature. The material is simple in preparation process, can be continuously produced, and has a bright industrial production application prospect.
