Abstract
A method for manufacturing an aerogel sheet according to the present invention includes: a step (a) of preparing a blanket having a plate shape; a step (b) of mixing silica sol with gelling catalyst to prepare a silica sol precursor; and a step (c) of injecting the silica sol precursor prepared in the step (b) to a surface of the blanket prepared in the step (a) through an injection device to gelate the silica sol precursor, wherein, in the step (c), the injection device injects the silica sol precursor while moving from one side to the other side of the surface of the blanket.
