Abstract
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 nano-silica 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.
