Abstract
The present invention relates to a method for manufacturing an aerogel sheet and comprises: a step (a) of impregnating an acid solution into a fiber sheet to clean the fiber sheet by using the acid solution and impregnating a binder solution into the fiber sheet that is cleaned by using the acid solution to manufacture a pre-processed fiber sheet; a step (b) of impregnating a silica precursor into the pre-processed fiber sheet; and a step (c) of a gelling catalyst into the fiber sheet into which the silica precursor is impregnated to gelate the silica precursor.
