摘要
将笼形八苯基硅倍半氧烷(OPS)应用于三元乙丙橡胶(EPDM)绝热材料,测定了EPDM/OPS绝热材料的力学性能、线烧蚀率、烟雾和密度等主要性能。结果表明,用OPS取代部分聚磷酸铵(APP)的EPDM绝热材料的线烧蚀率、烟雾和密度均明显降低,力学性能也有提高。
Octaphenylsilsesquioxane（OPS） was used in the insulator materials based on ethylene propylene diene monomer（EPDM） rubber.The mechanical properties,linear ablative rate,smoke production and density of the EPDM/OPS heat insulation materials were determined.Compared with the EPDM heat insulation materials without OPS,part replacement of ammonium phosphate（APP） by OPS decreases linear ablative rate,smoke production and density,and improves mechanical properties.
