curing characteristics and mechanical properties of (styrene butadiene rubber /ethylene propylene diene monomer)blend in the presence of a hybride of carbon black and nanocalay

This research examines the curing rheometric characteristics and mechanical properties of blends  based on styrene butadiene rubber (sbr) and ethylene propylene diene monomer (epdm) rubber in the presence of carbon black and nano clay(clohsite 15a). for this purpose, blends containing a certain percentage of both rubbers (50/50) and different amounts of nanoparticle were prepared. a rheometry test was performed on the samples and based on the obtained results, the samples were vulcanized and the tensile strength was measured on them. the results obtained from rheometry showed a decrease in scorch time, cure time and an increase in minimum torque in the samples containing nanoparticles. also, the tensile strength and elongation at break of them were increased.
