摘要
用埃洛石、三聚氰胺作为阻燃剂,制备了无卤阻燃聚丙烯(PP)复合材料。通过氧指数(OI)、垂直燃烧、万能力学仪、扫描电镜分析研究了埃洛石复配阻燃剂对PP阻燃性能、力学性能的影响。结果表明:埃洛石复配阻燃剂可使PP复合材料通过UL94燃烧性能测试,在提高材料OI的同时,保持了其优良的力学性能。
Halogen-free flame retarded polypropylene（PP） composites were prepared by mixing PP with melamine and halloysite. The effect of halloysite compound flame retardant on the flame retardancy and mechanical properties of PP were characterized by using oxygen index（OI）, UL- 94, electronic tensile testing machine and scanning electron microscope. The results show that： the flame retardancy of the system improves effectively with adding the melamine and halloysite system, and then the OI of the system increases and maintains the excellent mechanical properties.
