摘要

以二乙基次膦酸铝(ADP)为协效剂,与聚磷酸铵(APP)/季戊四醇(PER)传统膨胀型阻燃体系复配,通过熔融共混制备了膨胀阻燃聚丙烯(PP)。采用极限氧指数(LOI)、垂直燃烧测试、锥形量热仪、扫描电子显微镜和热重分析研究了阻燃PP的性能及相关作用机制。结果表明,ADP和APP/PER具有很好的协同阻燃作用,它不但可以同时提高阻燃体系的残炭量和炭层质量,有效抑制熔滴,还可以降低燃烧过程中的生烟量,是更加绿色的阻燃体系。当阻燃体系的总添加量为24%,APP/PER和ADP的质量比为6∶1时,阻燃PP的LOI可达到29.8%,垂直燃烧等级为V–0级,且生烟性比不添加ADP的体系下降了76.9%。阻燃机理研究表明,该体系是以凝聚相为主的凝聚相和气相协同阻燃机制。
        Intumescent ?ame retardant polypropylene(PP) was prepared by melt blending with aluminum diethylphosphinate(ADP) as a synergist and compounded with the traditional intumescent ?ame retardant system of ammonium polyphosphate(APP)/pentaerythritol(PER). The properties and retardant mechanism of the ?ame PP were studied by the limit oxygen index(LOI),the vertical burning test,cone calorimeter,scanning electron microscope and thermogravimetric analyser. The results show that ADP and APP/PER has a good synergistic ?ame retardant effect,which can not only improve the carbon residue and carbon layer quality of the ?ame retardant system,but also effectively inhibiting the melting droplets and reducing the amount of smoke generated in the combustion. It is a greener ?ame retardant system. When the mass ratio of APP/PER and ADP is 6∶1,and the ?ame retardant system total additive content is 24%,the LOI of ?ame retardant PP is 29.8%,the vertical combustion reachs V–0 grade,and the smoke generation is 76.9% lower than that of the system without ADP. The study of ?ame retardant mechanism shows that the system is dominated by condensed phase ?ame-retardant mechanism and accompanying simultaneously gas phase ?ame-retardant mechanism.
