| 中文摘要: |
| 以三元乙丙橡胶（EPDM）为主体材料，分别采用5种无卤氮磷系阻燃剂FR-680，206，AT-903C，FR35RP和FR21RP（用量为10份）制备阻燃EPDM胶料，考察5种无卤氮磷系阻燃剂对EPDM胶料性能的影响。结果表明：5种无卤氮磷系阻燃剂均能明显提高EPDM硫化胶的阻燃性能，EPDM硫化胶的极限氧指数均在30%以上；填充阻燃剂FR-680和FR35RP的EPDM硫化胶具有优异的物理性能，但其阻燃性能相对较差；填充阻燃剂FR21RP的EPDM硫化胶的拉伸强度为7.0 MPa，极限氧指数为39%，总热释放量最大值为83.43 MJ·m-2，总烟释放量最小值为462.42 m2·m-2，其综合性能最佳。 |
| 英文摘要: |
| In this study，flame-retardant ethylene-propylene-diene-propylene rubber （EPDM）
compounds were prepared by adding five halogen-free nitrogen phosphorus flame retardants，FR-680，206，
AT-903C，FR35RP and FR21RP（110 phr），respectively，and the effects of those five halogen-free nitrogen
phosphorus flame retardants on the properties of EPDM compounds were investigated. The results showed
that，all five halogen-free nitrogen phosphorus flame retardants could significantly improve the flame
retardant properties of the EPDM vulcanizates，and the limiting oxygen index of the EPDM vulcanizates was
above 30%. Moreover，the EPDM vulcanizates filled with flame retardant FR35RP and FR-680 had excellent
physical properties，but their flame retardant properties were relatively poor. It was found that the overall
properties of the EPDM vulcanizates filled with flame retardant FR21RP were the best，with a tensile strength
of 7. 0 MPa，a limiting oxygen index of 39%，a maximum total heat release（THR） rate of 83. 43 MJ·m-2，
and a minimum total smoke release（TSR） rate of 462. 42 m2·m-2. |
