摘要

Maleic anhydride grafted ethylene-propylene-diene monomer (MAH-g-EPDM) was prepared by peroxide-initiated melt grafting of MAH onto EPDM using a HAAKE internal mixer at 180°C and 60 rpm for 5 min and it was used as compatibilizer to enhance the compatibility of EPDM/Bt composites. The composites were prepared using a laboratory scale two roll mill, model XK-160 at room temperature. The addition of 10 parts per hundred rubber (phr) of MAH-g-EPDM into EPDM/Bt composite results in significantly improved tensile properties compared with the uncompatibilized EPDM/Bt composites. Curing behavior, tensile properties, solvent resistance, and the rubber-filler interaction of compatibilized and uncompatibilized EPDM/Bt composites were investigated. The cure time (t _(90)), scorch time (t _(S 2)), maximum torque (M _H), and minimum torque (M _L) of compatibilized composites were increased upon addition of MAH-g-EPDM. Compared with uncompatibilized EPDM/Bt composites, the tensile properties, solvent resistance, and rubber-filler interaction of compatibilized EPDM/Bt composites were all improved. SEM micrographs of tensile fractured surfaces of compatibilized EPDM/Bt composites showed a better dispersion of Bt and interfacial adhesion between EPDM and Bt compared with uncompatibilized EPDM/Bt composites.
