Abstract

The present invention relates to a method for manufacturing an aerogel blanket, and a low-dust high-insulation aerogel blanket manufactured by the present invention, the method: increasing the adhesive performance of silica aerogel by activating the surface of a substrate for a blanket and increasing the roughness and porosity of the surface of the substrate for a blanket since the etching of thesurface of the substrate for a blanket is induced by using an acidic solution; and simultaneously increasing mechanical flexibility and inhibiting the generation of dust by further carrying out a gelmodification step in which cracks are introduced to the aerogel.
