Abstract
In the present invention are provided a method for preparing a silica aerogel-containing blanket, and a blanket which includes a silica aerogel and is manufactured using the same, wherein the method includes a step for preparing a reaction solution by reacting a silazane-based surface modification agent with an alcohol-based compound, a step for preparing a silica gel-base material composite by adding a silica precursor, water, and a polar organic solvent to the reaction solution to prepare a silica sol, and then immersing a base material for a blanket in the prepared silica sol to gelate the silica sol, and a step for drying the silica gel-base material composite.
