Styrene butadiene rubber-organoclay nanocomposites were prepared with Cloisite 15A via melt intercalation. X-ray diffraction
and transmission electron microscopy indicated that the nanostructures are partially exfoliated and intercalated. The nanocomposites
exhibited great improvements in tensile strength and tensile modulus. The incorporation of organoclay gave rise to considerable
reduction of tan delta and increase in storage modulus in the rubbery region. It is shown that after 6 phr (parts per hundred
rubber) clay loading there is not much increase in the properties. The effect of carbon black (N330) on mechanical properties,
dynamic mechanical properties, heat build up, abrasion resistance in the nanocomposites having the optimized clay level (6
phr) was investigated. Optimum results were obtained with the addition of 25 phr carbon black. For comparison with the 6phr
nanoclay and 25phr N330 (high abrasion furnace carbon black) filled SBR composites, 40 phr N330 filled SBR composites was
used. The 6phr organoclay and 25phr N330 filled SBR nanocomposite showed better properties than 40phr carbon filled SBR compound.
These results indicate that 6phr organoclay can be replaced by 15 phr carbon black from the conventional SBR-carbon black
based tire tread compounds. The Dynamic mechanical analyzer (DMA) results revealed that the new tire tread compound gives
better rolling resistance and comparable wet grip resistance and lower heat build up than that of conventional tread compound. 相似文献
