Abstract
The present invention relates to a method for manufacturing an aerogel blanket, the method including 1) introducing a catalyzed sol and a substrate for a blanket into a reaction vessel to impregnate the catalyzed sol into the substrate for a blanket, and 2) rotating the substrate for a blanket into which the catalyzed sol is impregnated to perform gelation, wherein the catalyzed sol includes a silica precursor composition, and the silica precursor composition includes a silicate containing a hydrophobic group and a tetraalkyl silicate, wherein a molar ratio of the silicate containing a hydrophobic group and the tetraalkyl silicate is 60:40 to 98:2.
