Abstract
Provided is an aerogel blanket and a method for producing the same, wherein a catalyzed sol I sufficiently and uniformly impregnated into a blanket in an impregnation tank, and the catalyzed sol is allowed to stay in the impregnation tank for a specific time to control fluidity while achieving a viscosity at which the catalyzed sol can be easily introduced into the blanket, thereby forming a uniform aerogel in the blanket. As a result, the uniformity of pore structure and thermal insulation performance of an aerogel blanket are improved, the loss of raw materials is reduced through the impregnation process, the occurrence of process problems is reduced, and the generation of dust is reduced.
