摘　　要：通过熔融共混法制备了长玻纤增强聚丙烯/膨胀阻燃剂/硼酸锌(LGFPP/IFR/ZnB)复合材料,并测定了其阻燃性、热稳定性及力学性能;通过扫描电镜(SEM)观察燃烧后的微观形貌,考察了ZnB对LGFPP/IFR阻燃体系性能的影响。结果表明:适当用量的ZnB与IFR阻燃剂具有协同阻燃作用,可提高LGFPP/IFR体系的阻燃性、热稳定性及力学性能。在LGFPP/IFR阻燃体系中添加2%的ZnB,LGFPP/IFR/ZnB复合材料的氧指数提高到23.6%;拉伸强度、弯曲强度和冲击强度分别提高了10.7%、15.1%和31.9%。LGFPP/IFR/ZnB composite was prepared by melt blending, and the flame retardancy, thermal stability and mechanical properties were investigated. The micro morphology of composites after combustion was observed by SEM and the effect of ZnB on properties of LGFPP/IFR system was investigated. The results show that ZnB and IFR has a synergistic flame retardant effect on composites, and the flame retardant, thermal stability and mechanical properties of LGFPPIIFR flame retardant system improve with adding appropriate amount. The OI of LGFPP/ IFR/ZnB composite improves to 23.6%, tensile strength, flexural strength and impact strength increase by 10.7%, 15.1% and 31.9% respectively with adding 2% ZnB into LGFPP/IFR flame retardant system.
