INORGANIC FIBER MAT AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an inorganic fiber mat in which water resistance or hydrolysis resistance is improved and a method for producing the same.SOLUTION: The method for producing an inorganic fiber mat includes attaching an aqueous binder and reactive silicone oil to inorganic fibers. The aqueous binder contains: a (co)polymer (A) having at least two selected from a carboxyl group and an acid anhydride group; a cross-linker (B) containing a compound (B1) having at least two functional groups selected from a hydroxyl group, an amino group, and an imino group; and water.
