    Abstract: Provided are a solvent-substitution solvent for producing a hydrophobized aerogel and a method for producing a hydrophobized aerogel. The solvent-substitution solvent includes pentanol in an amount of 41 wt % to 100 wt % and n-butanol in an amount of 0 wt % to 59 wt %. The method includes performing a solvent substitution process using the solvent-substitution solvent. If the solvent-substitution solvent is used for solvent substitution and/or hydrophobization in an aerogel production process, water (moisture) contained in a wet gel may be effectively substituted with the solvent-substitution solvent, and the solvent-substitution solvent may easily be collected at a high degree of purity and may be reused if necessary. Therefore, the rate of solvent loss may be minimized. In addition, if the solvent-substitution solvent is used for solvent substitution, a hydrophobized aerogel may be obtained without having to perform a hydrophobizing process using an additional hydrophobizing agent such as a silylating agent.

    Abstract: The present invention relates to a method of manufacturing a mat containing aerogel and to a mat manufactured using this method. A method of manufacturing a mat containing silica aerogel according to an aspect of the invention includes: (S1) producing a wet gel by mixing water glass and alcohol in a reactor; (S2) modifying a surface of the wet gel by adding an organic silane compound and an organic solvent to the reactor and mixing; (S3) separating a upper liquid from a solution in the reactor and impregnating a fibrous matrix with the upper liquid; and (S4) drying the fibrous matrix impregnated with the upper liquid. According to an aspect of the invention, a mat containing silica aerogel can be manufactured using only water glass as raw material, even when applying the drying process in an ambient environment, without using expensive materials or supercritical apparatus.
