Beschreibung
Zusammenfassung:	Provided are a vacuum extraction type method of manufacturing an aerogel powder, which substantially reduces the cost of a solvent required in the cleaning process and greatly reduces the time required in the manufacturing process, an aerogel powder manufactured thereby, a method of manufacturing an aerogel non-woven fabric, an aerogel non-woven fabric manufactured thereby, and a complex heat insulator using the aerogel non-woven fabric. A method of manufacturing an aerogel powder comprises manufacturing the aerogel powder by replacing the solvent cleaning process with the vacuum extraction process after the solven displacement. A method of manufacturing an aerogel non-woven fabric comprises a step of spraying an aerogel solution onto the non-woven fabric in the needle punching step of the process of manufacturing a non-woven fabric. The method further comprises a step of gelling the aerogel solution-coated non-woven fabric, a step of aging the gelled non-woven fabric in an IPA solution, a step of displacing a solvent of the aged non-woven fabric with TMCS, a step of extracting a residual solvent by a vacuum pump, and a step of drying and heat-treating the resulting non-woven fabric.
