加入少量海泡石作为协效剂，对含磷、氮化合物的膨胀阻燃聚丙烯有显著的增强作用。采用极限氧指数（LOI）、UL-94、锥形量热仪（CCT）和热重分析（TGA）等测试手段对阻燃聚丙烯复合材料的燃烧性能和热稳定性进行了研究。添加0.5%的海泡石使LOI从29.8增加到31.8。低添加量的海泡石的添加似乎是低的热释放速率，总烟，和CO2的生产的最佳混合比。海泡石在机械性能方面也有明显的改善。
Intumescent flame-retardant polypropylene-containing phosphorus and nitrogen compounds were enhanced significantly by adding a small amount of sepiolite as a synergistic agent. The flame-retardant polypropylene composite was characterized by limiting oxygen index (LOI), UL-94, the cone calorimeter (CCT), and thermogravimetric analysis (TGA) to study the combustion behavior and thermal stability. The addition of 0.5% sepiolite increased the LOI from 29.8 to 31.8. The addition of sepiolite at a low additive amount appears to be an optimum blend ratio for the low heat release rate, total smoke, and CO2 production. Sepiolite also has a significant improvement in mechanical properties.
