The present invention relates to a method and to an apparatus for preparing a hydrophobic aerogel. The method for preparing a hydrophobic aerogel, for the process of reforming a wet gel into a hydrophobic aerogel through a well-known room temperature and atmospheric pressure system, comprises directly inserting a mesh-structured basket into a reactor, injecting the wet gel into the basket, installing an ultrasonic generator in a lower portion of the reactor to radiate ultrasonic waves to the interior of the reactor, and supplying nitrogen from the bottom to the interior of the reactor to promote a reaction and thus reforming the wet gel into a hydrophobic aerogel in a short amount of time. The apparatus for preparing an aerogel comprises a reactor for reforming well-known wet gel into a hydrophobic aerogel, a basket mounted on protrusions formed within the reactor, and an ultrasonic generator and nitrogen injection means installed in the lower portion of the reactor, whereby aerogel can be prepared in a short amount of time, thus achieving economical advantages. |
