Abstract
Modified montmorillonite（KH-570-OMMT） was obtained by intercalation modification of montmorillonite with modifiers cetyltrimethylammonium bromide and silane coupling agent KH-570, it was incorporated as filler into chlorinated butyl rubber （CIIR）/polypropylene （PP） thermoplastic vulcanizate （TPV） system, and the effects of filler amount on micromorphology, crystallization performance, dynamic mechanical properties, and physical and mechanical properties of CIIR/PP TPV were systema-tically studied. The results showed that KH-570-OMMT could improve the crystallization temperature and storage modulus of TPV; when the filler amount was less than 15 phr （mass）, both tensile properties and resilience of TPV were improved; the introduction of KH-570-OMMT could also make the damping peak of TPV shift toward the high temperature, and broaden the effective damping temperature range of the material.
