摘要:
The present invention relates to a method for producing a silica aerogel blanket, the method comprising recovering a supercritical waste liquid generated after performing a step of supercritical drying, neutralizing the recovered supercritical waste liquid by adding an acid thereto for recycling, and reusing the recycled supercritical waste liquid, and a silica aerogel blanket produced thereby.
