| titleOfInvention | Preparation method of toughened silica aerogel, toughened silica aerogel and application of toughened silica aerogel |
| abstract | The invention relates to the technical field of aerogel, in particular to a preparation method of toughened silica aerogel, the toughened silica aerogel and application thereof. Uniformly mixing a silicon source, an organic solvent and water, preparing wet gel through a sol-gel step, and then performing aging, solvent replacement, surface modifier modification, crosslinking and drying to obtain the toughened silica aerogel; the surface modifier is selected from one or more of 3-methacryloxypropyldimethylchlorosilane, acryloxypropyldimethylchlorosilane, 3-methacryloxypropyldimethylmethoxysilane and acryloxypropyldimethylmethoxysilane. The silicon dioxide aerogel disclosed by the invention has better toughness, wet gel can be dried under normal pressure without being damaged, the equipment investment is saved, the production efficiency is improved, the production cost is reduced, and the silicon dioxide aerogel can be applied to the fields of heat insulation materials, waste gas treatment materials, waste water treatment materials, catalysts and the like. |
