| 摘 要： | 以膨胀型阻燃荆(IFR)为阻燃荆、蒙脱土(MMT)为协效剂、PP-g-MAH为增容剂,对聚丙烯(PP)进行阻燃改性.研究了阻燃剂和协效剂对PP燃烧性能、力学性能和加工性能的影响,并运用热重分析(TGA)和差热分析(DTA)表征了阻燃PP的热降解过程,通过扫描电子显微镜(SEM)观察燃烧残余物的炭层形貌.结果表明,MMT的加入削弱了PP/IFR体系的阻燃性能和力学性能,但在一定程度上解决了体系燃烧时的浓烟现象;当IFR用量为35份时,体系的垂直燃烧性能达到FV-0级,燃烧残余物形成致密的炭层,且具有良好的力学性能和加工性能.

| Abstract: | PP were flame retardanted by intumescent flame retardant(IFR) and montmorillonite(MMT) with PP-g-MAH as the compastibilizer.The synergistic influence of IFR and MMT on the flammability,mechanical properties and rheological behavior of flame-retardant PP were investigated.The degradation progress of the composites and the obtained charred layers were analyzed by using TGA,DTA and SEM.The results showed that the addition of MMT deteriorated the flammability and mechanical properties of PP/IFR,but decreased th... |
