| titleOfInvention | A kind of low density SiO 2the preparation method of aerogel/sponge matrix material |
| abstract | The invention discloses a kind of low density SiOn 2 the preparation method of aerogel/sponge matrix material, it is characterized in that preparation method comprises the steps: that silicon source, dehydrated alcohol, deionized water, methane amide are 1:(10 ~ 20 by (a) in molar ratio): (2 ~ 7): the ratio mixing of (1 ~ 3), then adding with silicon source mol ratio is (0.001 ~ 0.01): an acidic catalyst of 1, stir fully hydrolysis at 0 ~ 60 DEG C after, add alkali lye adjust ph; B () is got mixing solutions in step (a) and is poured into and be placed with in the mould of sponge, leave standstill and obtain wet gel.C () adopts dehydrated alcohol to carry out 3 ~ 8 solvent exchanges to wet gel, each time swap is 8 ~ 24h, at CO after having replacedn 2 carry out supercritical drying under environment and can obtain low density SiOn 2 aerogel/sponge matrix material. |
