SBR/OMMT纳米复合材料的制备及性能研究

以聚苯乙烯（PS）低聚物为相容剂，用熔体插层法制备SBR/有机蒙脱土（OMMT）纳米复合材料，并对其结构及性能进行研究。结果表明，PS大分子能够插入OMMT层间形成复合物；采用熔体插层法使PS/OMMT纳米复合物在SBR基体中实现纳米级分散，可间接实现OMMT在SBR基体中的纳米级分散；当填充5份OMMT时，SBR/OMMT纳米复合材料具有较好的物理性能。;A SBR/OMMT nano-composite was prepared by using polystyrene low-polymer(PS) as compatibilizer through melting intercalation method，and its structure and properties were investigated.The results showed that the PS macromolecule could be intercalated into OMMT layers to form a composite；the PS/OMMT composite could be dispersed in SBR matrix on nano-level to indirectly realize the dispersion of OMMT in SBR matrix on nano-level；and a SBR/OMMT nano-composite with better physical properties was obtained by using 5 phr OMMT
