AEROGEL PARTICLE AND METHOD OF PRODUCING THE SAME

摘要

An aerogel particle is produced by following processes. A mixing process: an alkoxysilane compound is mixed with an organic solvent to form a first mixed solution. A hydrolysis process: an acid catalyst is added into the first mixed solution to perform a hydrolysis reaction, thereby obtaining a sol. A condensation process: an alkali catalyst is added into the sol to perform a condensation reaction, and a hydrophobic dispersion solvent is added and stirred during the condensation process, thereby subjecting sol to be gelled when it is stirred, further producing the aerogel particle with a uniform structure.

1. A method of producing an aerogel particle, comprising:
performing a mixing process, wherein an alkoxysilane compound is mixed with an organic solvent to form a first mixed solution; performing a hydrolysis process to the first mixed solution, wherein an acid catalyst is added into the first mixed solution to perform a hydrolysis reaction, thereby forming a sol; and performing a condensation process to the sol, wherein an alkali catalyst is added into the sol to perform a condensation reaction, and a hydrophobic dispersion solvent is added and stirred during the condensation process, thereby subjecting the sol to be gelled when it is stirred, further producing a second mixed solution including the aerogel particle.
