METHOD FOR RECYCLING SUPERCRITICAL WASTE LIQUID TO BE GENERATED DURING PROCESS FOR MANUFACTURING SILICA AEROGEL BLANKET

摘要

The present invention relates to: a method for recycling supercritical waste liquid to be generated during a process for manufacturing a silica aerogel blanket; and a method for manufacturing a silica aerogel blanket by reusing the supercritical waste liquid recycled thereby and, more specifically, provides: a method for recycling supercritical waste liquid; and a method for manufacturing a silica aerogel blanket, which can reduce manufacturing costs and, simultaneously, prevent the deterioration of thermal insulation performance of a silica aerogel blanket, by adding a metal salt to supercritical waste liquid by the recycling method.
