Abstract
Provided is a silica aerogel blanket capable of preventing deterioration of heat insulating performance while reducing dust generation, and method for manufacturing the same. The method manufactures a low-dust silica aerogel blanket by separately adding a silica sol to prevent an opacifying agent from being exposed to the surface of the silica aerogel blanket.
