摘要: 通过熔融共混的方法制备了聚丙烯/埃洛石纳米管(PP/HNTs)复合材料,并表征了复合材料的力学性能、界面性能和阻燃性能。结果表明,HNTs对阻燃PP发挥进一步阻燃作用,当HNTs含量为2 %时,其极限氧指数可达32.0 %,较阻燃PP提高了2 %;其垂直燃烧性能可达UL 94 V-0级;尤其重要的是,HNTs的加入显著提高了材料的力学性能,含2 %HNTs的复合材料的综合性能最佳,冲击强度为5.4 kJ/m2,拉伸强度为36.5 MPa,弯曲强度为41.4 MPa。

Abstract: A series of polypropylene/holloysite (PP/HNTs) composites were prepared by melt blending, and their mechanical properties, interfacial and flame retardancy were characterized. The results showed that HNTs had synergistic effect with other additives on improving the flame retardancy of the composites. The limiting oxygen index of the composites reached 32 %, and vertical burning behavior with 2 % HNTs was UL 94 V-0 class, and impact strength, tensile and flexural strength were 5.4 kJ/m2, 36.5 MPa, and 41.4 MPa, respectively.
