| 摘 要： | 研究了抗氧剂1010、168与光稳定剂622对线形低密度聚乙烯（PE-LLD）抗紫外光老化性能的影响，并通过拉伸性能测试和凝胶渗透色谱等手段对PE-LLD老化前后的拉伸性能、相对分子质量及其分布进行了研究。结果表明，纯PE-LLD经紫外光老化3 d后，其断裂伸长率保留率就降低到50 %以下；单独添加0.15份抗氧剂1010、168或光稳定剂622，PE-LLD的断裂伸长率保留率分别在紫外光老化7、6和15 d后降低到50 %以下；抗氧剂1010、168与光稳定剂622复配使用时，可显著提高PE-LLD的抗紫外光老化性能，具有明显的协同效应。

| Abstract: | The UV stabilizing effects of antioxidant 1010,168 and light stabilizer 622 on linear low density polyethylene(PE-LLD) were studied.Mechanical testing and gel permeation chromatography were carried out to study tensile properties and molecular weight of PE-LLD before and after UV-light aging.When antioxidant and light stabilizer were absent,the reserved elongation at break of PE-LLD was less than 50 % after UV-light aging for 3 d.With adding 0.15 phr of antioxidant 1010,168 and light stabilizer 622 separate... |
