| titleOfInvention | Process for preparing low density hydrophobic silica powder |
| abstract | The present invention relates to a process for producing low density hydrophobic silica powder. According to the preparation method of the present invention, an organic additive such as an acid / base catalyst, an emulsifier and a dispersant, which induces a gelation reaction by excluding the sol preparation step of acid or ion exchange treatment by obtaining a gel directly from an inexpensive water glass using alcohol. High porosity of more than 95% and low density of less than 0.1g / mL by completing the hydrophobization reaction in a short time without using a small amount of modifier and organic solvent and drying for a short time at low temperature below 200 ° C under normal pressure The hydrophobic silica powder having the composition can be prepared, and thus the silica powder can be prepared very economically and quickly and simply.n n n n Water glass, alcohol, low density, hydrophobic, silica, airgel |
