摘要
通过熔融共混法制备了氢化苯乙烯-丁二烯-苯乙烯(SEBS)/聚丙乙烯(PP)/Al(OH)3/有机蒙脱土(OMMT)复合材料,并采用锥形量热仪、拉伸测试仪等测试了材料的阻燃性能和力学性能。测试结果表明,添加Al(OH)3,使SEBS/PP/OMMT复合材料的热释放速率、峰值热释放速率和总热释放显著降低,且随着Al(OH)3添加量的增加,复合材料的峰值热释放速率降低愈明显;体系中OMMT和Al(OH)3添加量(质量分数)均在10%时复合材料的综合性能最佳。
SEBS/PP/Al（OH）3/OMMT composites were successfully prepared by a twin screw blender.The flammability and mechanical properties of the composites were characterized by the cone calorimeter and a tensile testing machine.The results showed that the flammability of SEBS/PP/OMMT could be significantly improved by the Al（OH）3 addition.As the added content of Al（OH）3 increased,the heat release rate,pHRR,and total heat release decreased.The optimal properties of the SEBS/PP/Al（OH）3/OMMT composites were obtained when the content of Al（OH）3 was 10%,and OMMT amount was 10%.
