Title: METHOD FOR MANUFACTURING AEROGEL BLANKET, AND AEROGEL BLANKET MANUFACTURED THEREBY
Abstract:
The present invention relates to a method for manufacturing an aerogel blanket having excellent hydrophobicity at a high temperature, and an aerogel blanket manufactured thereby. The present invention mixes a silica sol and a hydrophobic aerogel powder so as to use the same as an aerogel precursor, thereby enabling a hydrophobic aerogel to be present in the aerogel surface structure, contained in an aerogel blanket, and even in the internal structure thereof, and thus the present invention can have high hydrophobicity and can have excellent hydrophobicity retentiveness even during high temperature application.
