Method for preparing hydrophobic silica aerogel |
| abstract |
The present invention relates to a method for preparing a silica precursor solution by decomposing a silazane compound as a surface modifier through reflux and adding an alkoxysilane based reaction solution in which ammonia has been previously removed to a silica precursor solution to perform a gelation reaction without a catalyst, To provide a hydrophobic silica airgel preparation capable of producing a silica airgel and capable of reducing the occurrence of salt upon supercritical drying. |
