| titleOfInvention | Preparation method of low-thermal-conductivity TiO2/SiC-Al2O3 aerogel-SiO 2 fibrofelt composite material |
| abstract | The invention discloses a low thermal conductivity TiO 2 /SiC‑Al 2 O 3 aerogel-SiO 2 A method of making a fiber mat composite comprising: mixing aluminum nitrate nonahydrate, water and alcohol, and adding TiO 2 Or SiC, stirring for 1-2 h until the aluminum salt is completely hydrolyzed; then adding propylene oxide and rapidly stirring for 3min to obtain mixed sol; injecting the mixed sol into SiO 2 Waiting for gelation in the fibrofelt for 10-30 min, aging for 24h after gelation, then adding alcohol for solvent exchange soaking for 3 times, each time for 24h, and finally performing supercritical drying to obtain TiO 2 /SiC‑Al 2 O 3 aerogel-SiO 2 A fiber mat composite. The TiO being 2 /SiC‑Al 2 O 3 aerogel-SiO 2 The fiber mat composite has low thermal conductivity; can be widely applied to the production and life of the people, such as the fields of heat preservation and insulation, aerospace and the like. The method has the advantages of simple experimental process and low raw material cost, and is expected to realize industrialization. |
