Title:
AEROGEL BLANKET AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/054644
Kind Code:
A1
Abstract:
The present invention relates to an aerogel blanket and a manufacturing method therefor, the method sufficiently and uniformly impregnating a catalyzed sol into a blanket in an impregnation tank, and allowing the catalyzed sol to remain in the impregnation tank for a specific time so as to control flowability while achieving a viscosity that enables the catalyzed sol to be readily injected into the blanket, so that the aerogel can be uniformly formed inside the blanket, and thus the uniformity of pore structure and insulation performance of a manufactured aerogel blanket is improved, the loss of a raw material through an impregnation process is reduced, fewer processing problems occur, and dust generation is reduced.
