| titleOfInvention | Preparation method of silicon dioxide aerogel composite material |
| abstract | The invention relates to preparation and a method of a silicon dioxide aerogel composite material. The silicon dioxide aerogel composite material takes tetraethyl orthosilicate as a silicon source and industrially-produced glass fibers or fiber cotton materials as a reinforcing body. Firstly, composite wet gel is prepared by adopting a fiber surface acid treatment process or an acid treatment and coupling agent crosslinking common treatment process and a sol-gel method, then, the composite wet gel is aged, solvent-replaced and modified, and finally, the silicon dioxide aerogel composite material is prepared under the normal-pressure drying. The prepared silicon dioxide aerogel composite material has the characteristics of high porosity, high specific surface area, low density, low dielectric constant, low thermal conductivity and the like and also has good formability, and functional materials with different properties and structures can be prepared as required. The preparation and the method have the advantages of simple synthesis process, low raw material cost and low equipment requirements; and the prepared composite aerogel has a certain mechanical property, is enlarged in the application field and can be taken as building heat-insulation and sound-insulation materials, transportation pipeline energy conservation and environmental protection material and fire protection and heat insulation materials. |
