Quaternary ammonium salts as modifiers of bentonites used as fillers of epoxy resin-matrix composites
Bentonite was modified with 3 quaternary ammonium salts and used for filling a corn. epoxy resin (1.5-4.5 by mass) to decrease the flammability of the resulting composite material. An increase in flammability resistance and O(2) index was achieved. The modification of bentonite with mixed RPhCH(2) Me(2)NCl (R=C(10)H(21) to C(18)H(37)) salt was of particular advantage.
