通过FTIR、 XRD、 TEM和辐照前后力学性能的测试，对蒙脱土增强二苯醚亚苯基硅橡胶的结构、耐辐照性能进行了研究。结果表明，钠基蒙脱土（ Na-MMT）经插层剂三十六烷基甲基溴化铵处理后，得到有机化蒙脱土（ OMMT）， OMMT的层间距比Na-MMT提高近65％； OMMT在二苯醚亚苯基硅橡胶中实现了纳米插层分散； OMMT增强二苯醚亚苯基硅橡胶的耐辐照性能优于其它常用粒状填料（沉淀法白炭黑、炭黑）增强的二苯醚亚苯基硅橡胶，经5×108 Gy辐照后，沉淀法白炭黑和炭黑增强二苯醚亚苯基硅橡胶的邵尔A硬度增加了11～12度，而OMMT增强二苯醚亚苯基硅橡胶的硬度仅增加了7度。

The structure , radiation resistance of montmorillonite reinforcing diphenyl ether phenylene sili-cone rubber ( DEP) composites were investigated by FTIR , XRD, TEM and mechanical properties before and after the radiation.Results showed that the organic montmorillonite (OMMT) was obtained by inserting into dioctyldecyltrimethylammonium bromide and the layers distances of OMMT were extended 65% compared to those of Na-MMT.Furthermore , the radiation resistance of OMMT/DEP composites was much better than those of the regular granule filler/DEP composites .Shore A hardness of the OMMT/DEP composites increased 7, and that of regular granule filler/DEP composites increased 11-12 after 5 ×108 Gy radiation.
