| titleOfInvention | Preparation method of silicon dioxide aerogel composite material and silicon dioxide aerogel composite material |
| abstract | The invention relates to the technical field of aerogel, in particular to a preparation method of a silicon dioxide aerogel composite material and silicon dioxide aerogel. Uniformly mixing a silicon source, an organic solvent and water, preparing wet gel through a sol-gel step, and then aging, absolute ethyl alcohol displacement, treating by using a treating agent, crosslinking and drying, wherein the treating agent is a normal hexane solution of vinyl hydroxyl silicone oil, mercaptopropyl silicone oil and a photoinitiator. The silica aerogel composite material has better strength, wet gel can be dried under normal pressure without being damaged, equipment investment is saved, production efficiency is improved, production cost is reduced, and the silica aerogel composite material can be applied to the fields of heat insulation materials, waste gas and wastewater treatment materials, catalysts and the like. |
