摘要
以工程应用较多的线型低密度聚乙烯(LLDPE)和聚丙烯(PP)为研究对象,试件分组、分批在高低温湿热老化、荧光紫外老化、自然环境老化条件下分别进行老化试验,然后老化试件进行了力学性能测试与热分析试验。研究了线型低密度聚乙烯、聚丙烯材料在不同的老化方式下的老化性能。
Linear low density polyethylene （LLDPE） and polypropylene （PP） for engineering applications were studied. The specimens were aged in batches and under different aging modes including high-low temperature-humidity aging, fluorescence uhraviolet aging and natural weathering. The mechanical properties and thermal analysis tests for the aged specimens were carried out. The aging properties of LLDPE and PP in different aging modes were studied.
