Abstract:
The present invention relates to a hydrophilic silica aerogel blanket for ultra-high temperature insulation, a production method thereof, and a construction method thereof. More specifically, the present invention provides a production method a hydrophilic silica aerogel blanket, the method capable of strengthening the structure of a silica gel by adding a basic catalyst in an aging step, reducing processing time and cost by omitting a surface modification step, thereby reducing manufacturing cost, and suppressing the generation of a bad odor during construction by fundamentally blocking a volatile organic compound (VOC), a hydrophilic silica aerogel blanket produced thereby, and a construction method of a hydrophilic silica aerogel blanket, the method capable of suppressing the generation of a bad odor when constructing the hydrophilic aerogel blanket on an ultra-high temperature piping equipment, and at the same time, preventing the loss of heat insulation performance due to moisture in the air.

Claim (Index 1):
A production method of a hydrophilic aerogel blanket comprising:\n 1) preparing a silica sol by mixing a silica precursor, alcohol, and an acidic aqueous solution; 2) adding a basic catalyst to the silica sol, and then depositing the silica sol added with the basic catalyst in a base material for blanket; 3) subjecting the silica sol to a gelation reaction while being in a state of being deposited in the base material for blanket; 4) adding a mixed solution of a basic catalyst and an alcohol to the silica gel produced upon the completion of the gelation reaction and aging the silica gel added with the mixed solution, wherein the basic catalyst of Step 4) comprises ammonium hydroxide or potassium hydroxide, wherein the ammonium hydroxide is added in an amount of 10 to 20 vol % based on the alcohol, or the potassium hydroxide is added in an amount of 0.05 to 0.15 g/L based on the alcohol; and 5) drying the aged silica gel.
