ternary nr/br/sbr rubber blend in the presence of nano additives

A ternary nanocomposite containing natural rubber, butadiene rubber, and styrene-butadiene rubber (nr/br/sbr blend) was prepared in 25/25/50 (phr), on which the effect of adding carbon black, nano clay )c15a), and nanosilica was examined. rheometric, tensile, and hardness measurement tests were performed on the prepared samples. the nano silica-containing sample showed an inhibitory effect in curing, while the modified nano clay-containing sample showed an accelerating effect on the curing process. the results revealed that the presence of nano-silica caused higher elongation at break. tem analysis was performed from cross-linked samples to ensure the exfoliation of nano additives in the matrix. the results confirmed the suitable distribution and dispersion of the nanoparticles in the composite samples.
