Abstract
A wet gel granule of aerogel is prepared by the following steps: mixing step: mixing with an organic mixed solvent to form a mixed solution; hydrolysis step: adding an acid catalyst to the mixed solution for carrying out a hydrolysis reaction, and adding a dispersion solvent during the condensation reaction, and agitating to gel the mixed solution during agitation and produce multiple hydrophilic or hydrophobic wet gel granules of aerogel. The overall preparation speed can be shortened quickly and at the same time the hydrophilic or hydrophobic wet gel granules of aerogel wet glue particles are prepared to increase the production efficiency of the wet gel granules of aerogel.
