Abstract

Provided is a method for manufacturing an aerogel blanket, and an aerogel blanket having uniform thermal conductivity inside a substrate, wherein the method is capable of simplifying manufacturing equipment by performing gelation while rotating a substrate for a blanket into which a catalyzed sol is impregnated, improving manufacturing efficiency by controlling manufacturing time regardless of the thickness of the aerogel blanket, and improving thermal conductivity by uniformly forming aerogel in the substrate for a blanket.

Claims (6)

1. An aerogel blanket, comprising:

a substrate for a blanket; and

an aerogel, and the aerogel is formed inside and on the surface of the substrate, the aerogel blanket having a deviation between the highest value of the thermal conductivity of the aerogel blanket and the lowest value of the thermal conductivity thereof of 5.0 mW/m·K or less, and having a moisture impregnation rate of 1.1 wt % to 4.5 wt %.

2. The aerogel blanket of claim 1 , wherein the aerogel has a modified surface comprising a hydrophobic functional group that renders the surface hydrophobic.

3. The aerogel blanket of claim 2 , wherein the hydrophobic functional group is from an organosilane compound.

4. The aerogel blanket of claim 3 , wherein the organosilane compound is selected from the group consisting of trimethylchlorosilane (TMCS), hexamethyldisilazane (HMDS), trimethylethoxysilane, ethyltriethoxysilane, and phenyltriethoxysilane.
