Title:
METHOD FOR MANUFACTURING SILICA AEROGEL-CONTAINING BLANKET, AND SILICA AEROGEL-CONTAINING BLANKET MANUFACTURED THEREBY
Document Type and Number:
WIPO Patent Application WO/2016/167494
Kind Code:
A1
Abstract:
The present invention provides a method for manufacturing a silica aerogel-containing blanket, and a silica aerogel-containing blanket manufactured thereby, the method comprising the steps of: preparing a reaction solution by reacting a silazane-based surface modifier and an alcohol-based compound; preparing a silica gel-substrate composite by adding a silica precursor, water and a polar organic solvent to the reaction solution so as to prepare a silica sol, and then dipping a substrate for a blanket into the same so as to gellify the same; and drying the silica gel-substrate composite. The silica aerogel-containing blanket, which has low thermal conductivity and excellent mechanical flexibility by comprising a silica aerogel having high hydrophobicity and excellent physical properties, and particularly, high porosity, can be manufactured by using a minimum amount of a surface modifier without an additional surface modification step through the manufacturing method.
