Hybridized aerogel having high temperature stability and high thermal insulation property, method of manufacturing hybridized aerogel, aerogel-based insulator and method of manufacturing aerogel-based insulator

A method of manufacturing a hybridized aerogel comprising:

• preparing a silica sol including a silica precursor, a first organic solvent, and a first acidic catalyst;
• preparing an opacifier sol including an opacifier precursor, a second organic solvent, a gelation inducing agent, and a second acidic catalyst;
• forming a mixed sol by mixing the silica sol and the opacifier sol;
• forming a hybridized gel in which a silica gel and an opacifier gel are mixed by adding a basic catalyst to the mixed sol and making the mixed sol to be gelled;
• and
• acquiring a hybridized aerogel in which a silica aerogel and an opacifier aerogel are mixed by removing solvent from the hybridized gel.

A method of manufacturing aerogel-based insulator comprising:

• preparing an opacifier sol including an opacifier precursor, a second organic solvent, a gelation inducing agent, and a second acidic catalyst;
• forming a mixed sol by mixing the silica sol and the opacifier sol;
• forming a hybridized gel including a silica gel and an opacifier gel gelated from the mixed sol, and combined with a matrix by adding a basic catalyst to the mixed sol, and impregnating the matrix into the mixed sol to which the basic catalyst is added;
• and
• acquiring an aerogel-based insulator including the matrix and a hybridized aerogel combined therewith by forming the hybridized aerogel in which a silica aerogel and an opacifier aerogel are mixed by removing solvent from the hybridized gel.
