High Performance Nanocomposite based on Organoclay and Blends of Different Types of SBR with BR

摘要

Nanocomposites based on SBR/BR blends and organoclay (Cloisitel5A) in presence of carboxylated nitrile rubber (XNBR) used as compatibiliser were prepared by employing a solution process as well as mechanical mixing on two-roll mill and internal mixer. The dosage of organoclay and XNBR was optimized and the nature of SBR varied. The mechanical properties of nanocomposites improve as the carboxyl group content in XNBR increases. Highly exfoliated structure of clay and excellent mechanical properties were obtained by all three mixing techniques, however internal mixer showed the best properties and 2 rolls mill mixing was the most difficult.
