摘　　要：为研制新型少烟、低密度、耐烧蚀材料,将笼形八乙烯基硅倍半氧烷(OVP)与三元乙丙橡胶(EPDM)通过双辊混炼机制成无机-有机纳米杂化烧蚀材料,考察了材料的力学、烧蚀、低特征信号和密度等主要性能。结果表明,用OVP取代部分聚磷酸铵(APP)后烧蚀材料的线烧蚀率显著降低,从0.077mm/s降低到0.056mm/s,同时烟雾和密度也有所降低。In order to prepare insulator material with low linear ablative rate, smoke and density, the inorganicorganic nanostructured ablative material was prepared with octavinylsilsequioxane （OVP） and ethylene propylene diene monomer rubber （EPDM） by twin roller mixer. The mechanical properties, linear ablative rate, smoke and density of the EPDM insulator materials were determined. The results show that compared with the EPDM insulator materials containing ammonium phosphate, part replacement of OVP for APP lowered linear ablative rate greatly, from 0. 077mm/s to 0. 056mm/s, smoke and density also declined.
