摘要
研究了聚磷酸铵(APP)、APP/红磷并用对阻燃乙丙橡胶的物理机械性能及阻燃性能的影响。结果表明,APP/红磷并用与单用APP相比,对乙丙橡胶的物理机械性能无明显影响;APP/红磷并用有明显的协同阻燃效应,APP/红磷并用比单用APP阻燃效果要好,不仅可以提高乙丙橡胶的垂直燃烧等级,也可以提高其氧指数。
The influence of ammonium polyphosphate （APP）, and APP/red phosphorus （P） on the flame retardance and mechanical properties of ethylene-propylene-diene monomer （EPDM） was in- vestigated. The results showed that the mechanical properties of the EPDM filled with APP/P were al- most the same as the EPDM filled only with APP. APP and P had obvious synergistic flame retardant effect. The flame retardancy of APP and P was better than that of APP. APP and P could increase not only vertical flammability rating but also the LOI.
