Abstract (en)
[origin: WO2015014813A1] A process for the production of an aerogel material comprises the following steps: a) preparation of a silicon oxide sol in an alcoholic solvent mixture; b) triggering of the gelation of the sol by adding base, giving a gel, and optionally ageing of the gel; c) hydrophobicization of the optionally aged gel; d) removal of the solvent mixture by subcritical drying, during which the aerogel material is formed. The silicon oxide sol formed in step a) comprises at least one acid-catalytically activatable hydrophobicization agent, where the volume fraction of the hydrophobicization agent in the sol is 5 to 60%. The hydrophobicization in step c) is induced as a result of release or addition of at least one hydrophobicization catalyst acting in combination with the hydrophobicization agent.
