The present invention relates to a method for manufacturing an aerogel blanket, the method comprising the steps of: preparing a wet gel blanket containing an organic solvent; feeding the wet gel blanket to a supercritical extraction apparatus and drying the wet gel blanket by using supercritical carbon dioxide; reducing the pressure of the supercritical extraction apparatus; and supplying gas-phase carbon dioxide to the pressure-reduced supercritical extraction apparatus to dry the wet gel blanket. La présente invention concerne une méthode de fabrication d'une couche d'aérogel, la méthode comprenant les étapes consistant à : préparer une couche de gel humide contenant un solvant organique ; fournir la couche de gel humide à un appareil d'extraction supercritique et sécher la couche de gel humide à l'aide de dioxyde de carbone supercritique ; réduire la pression de l'appareil d'extraction supercritique ; et fournir du dioxyde de carbone en phase gazeuse à l'appareil d'extraction supercritique à pression réduite pour sécher la couche de gel humide. 본 발명은 에어로겔 블랭킷 제조방법에 관한 것으로, 유기 용매를 포함하는 습윤겔 블랭킷을 제조하는 단계; 습윤겔 블랭킷을 초임계 추출장치에 투입하고, 초임계 이산화탄소를 이용하여 습윤겔 블랭킷을 건조하는 단계; 초임계 추출장치의 압력을 감압하는 단계; 및 감압된 초임계 추출장치에 기상의 이산화탄소를 공급하여 습윤겔 블랭킷을 건조하는 단계를 포함하는 에어로겔 블랭킷 제조방법에 관한 것이다.
