| 研究制备工艺和阻燃剂用量对EPDM/PP阻燃热塑性硫化胶(TPV)性能的影响。结果表明，采用十溴联苯醚(FR-10)/三氧化二锑并用阻燃体系，阻燃剂在动态硫化前加入，EPDM/PP TPV的阻燃性能较好，但物理性能稍差，阻燃剂用量较大时，EPDM/PP TPV的阻燃性能较好，但拉伸强度减小；采用FR-10/三氧化二锑/氢氧化镁并用阻燃体系，氢氧化镁在动态硫化前加入，EPDM/PP TPV的阻燃性能稍好，物理性能和挤出外观质量略差，氢氧化镁用量对EPDM/PP TPV的阻燃性能影响不大。采用FR-10/三氧化二锑/氢氧化镁并用阻燃体系，氢氧化镁在动态硫化前加入，可制备低硬度阻燃低发烟EPDM/PP TPV。 |

| The effects of the preparation and the addition level of flame retarder on the properties of flame retardant EPDM/PP TPV were investigated.The results showed that an EPDM/PP TPV with better flame retardance and somewhat poorer physical properties was obtained by using the blending flame retardant system of decabromo-diphenyl oxide (FR-10)/antimony trioxide (Sb2O3) adding the flame retarder before dynamic vulcanization，and an EPDM/NBR TPV with better flame retardance and lower tensile strength was obtained by adding high level of flame retarder；and an EPDM/PP TPV with a little better flame retardance and somewhat poorer physical properties and extrudate appearance was obtained by using the blending flame retardant system of FR-10/Sb2O3/magnesium hydroxide[Mg(OH)2]and adding Mg(OH)2 before dynamic vulcanization，and the addition level of Mg(OH)2 had little effect on the flame retardance of EPDM/NBR TPV.A flame retardant EPDM/NBR TPV with low hardness and smoke emission was obtained by using blending flame retardant system of FR-10/Sb2O3/Mg(OH)2 and adding Mg(OH)2 before dynamic vulcanization. |
