摘要

In this study, halloysite nanotubes (HNTs) were used to reinforce ethylene propylene diene monomer (EPDM) and chlorinated isobutylene-isoprene rubber (CIIR) blend composites. The effects of HNT loading on cure characteristics, mechanical properties, rebound resilience, swelling resistance, compression set, crosslinking density, and abrasion resistance were systematically evaluated. With increasing HNT content, minimum torque, maximum torque, delta torque, and cure rate index increased, while scorch time and optimum cure time decreased. Tensile strength and stress at 100% elongation increased up to 6 phr of HNTs, showing improvements of 76.7% and 49%, respectively, compared to the unfilled blend. Tear strength increased continuously with increasing HNT loading, reaching a 54.4% improvement at the highest concentration. However, elongation at break and rebound resilience declined by 10% and 31%, respectively, as HNT content increased. Crosslinking density increased up to 6 phr and then declined, showing a similar trend to the swelling resistance. Compression set values rose with increasing HNT loading. These results indicate that 6 phr of HNT provides optimal performance in balancing reinforcement and elasticity.
