摘要
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 （SbzO3） 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 EMg（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/Sb2 O3/Mg（OH）z and adding Mg（OH）z before dynamic vulcanization.
