摘要
以多种物质的纳米粒子组成的纳米复合粒子添加于聚乙烯中,经挤出吹塑制成的纳米改性棚膜为研究对象,通过曝晒和加速老化实验,分析与老化特征有关的断裂伸长率保留率,进行全面的对比测试。研究结果表明:纳米复合粒子对紫外线有吸收屏蔽作用,可使纳米改性棚膜的耐老化性能大大提高。
A kind of nanocomposite particles composed of variety of substance nanoparticles was added in PE,and the modified PE was blown into film.The aging characteristics and retention of elongation break of the film were analyzed and compared through exposure and accelerated aging test.The results show that：the nanocomposite particles can absorb and shield the ultraviolet ray,and then the aging resistance of modified film improves greatly.
