摘　　要：采用混炼插层法制备有机蒙脱土(OMMT)/NR纳米复合材料,研究硅烷偶联剂对其结构和性能的影响。结果表明,与NR相比,OMMT/NR纳米复合材料的物理性能、热稳定性和动态力学性能均有所提高;采用硅烷偶联剂KH-560改性的OMMT制备的纳米复合材料各项性能均优于采用硅烷偶联剂KH-550改性的OMMT制备的纳米复合材料。The OMMT/NR nanocomposites were prepared by melt-intercalation technique,and the effects of silane coupling agent on the structure and properties of OMMT/NR nanocomposite were in- vestigated. The results showed that the physical properties, thermal stability and dynamic properties of OMMT/NR nanocomposites were improved when composites made by silane coupling agent KH-560 composites made by silane coupling agent KH-550 compared to those of NR; the properties of nano-modified OMMT were better than those of nano-modified OMMT.
