MANUFACTURING METHOD FOR SILICA AEROGEL BLANKET AND MANUFACTURING APPARATUS THEREFOR

The present invention relates to a method for producing a silica aerogel blanket and an apparatus for producing the same, which are capable of easily controlling the physical properties of a silica aerogel blanket by separately injecting silica sol and a gelation catalyst to control gelation time, improving aerogel pore structure to be uniform and improving thermal insulation performance by sufficiently and uniformly impregnating the silica sol and the gelation catalyst into a blanket, reducing the loss of silica sol and gelation catalyst by allowing the silica sol and the gelation catalyst to pass on an ascending slope before gelation to remove any excessive silica sol and gelation catalyst exceeding an appropriate impregnation amount, and providing a silica aerogel blanket having less process trouble, and less dust.
