摘　　要：以纳米TiO_2、SiO_2为添加剂,利用它们能吸收、反射紫外线的特性,使之与聚丙烯(PP)共混,赋予PP抗紫外线性能,延长了PP的使用寿命。通过力学性能、熔体流动速率测定和红外光谱及差示扫描量热分析(DSC)等手段,对加入纳米材料的PP试样进行了分析,研究了PP的抗紫外性能。With nanomaterial TiO2 and SiO2 as additives and using their characteristics of absorbing and reflecting UV light, they were compounded into polypropylene to improve the ultraviolet-resistant property and prolong the service life of PP. The samples of PP filled with nanomaterial were analized by the means of the determination of the mechanical property and the melt flow rate, infrared spectrum analysis and DSC to study on the ultraviolet-resistant property of PP.
