Abstract
The production method of the present invention can reuse a non-impregnated catalyzed sol, which has been typically discarded, by recovering the catalyzed sol, which is not impregnated in impregnating of a catalyzed sol into a blanket base, to stop gelating the catalyzed sol, and then using this in subsequently preparing a catalyzed sol.
