摘要
采用机械混炼法制备了溴化丁基橡胶/有机蒙脱土(BIIR/OMMT)纳米复合材料,采用SEM和XRD对其亚微观结构进行了表征,并对其耐寒性能和阻透性能进行了研究。实验结果表明:OMMT片层以剥离状态分散于BIIR基体中;添加OMMT之后,BIIR的交联密度明显提高;OMMT能够略微降低BIIR的耐寒性能;OMMT片层具有优异的阻透效应,能够明显提高BIIR的热稳定性能和耐油性能。
The bromobutyl rubber/organic montmorillonite（BIIR/OMMT） nanocomposites were prepared by mechanical blending.The microstructure of nanocomposites were characterized by SEM and XRD,and the permeability resistance properties and low temperature resistance characteristics were also investigated.The results showed that：The OMMT layers were exfoliated in the BIIR matrix;The introduction of OMMT could improve the crosslink densities of BIIR remarkably;The OMMT decreased the low temperature resistance properties of BIIR slightly;The OMMT had excellent obstruction effect,improving the thermal stability and oil resistance properties of BIIR significantly.
