摘　　要：在不同温度下对滚塑包装箱用材料聚乙烯(LLDPE)进行人工加速热氧老化试验。测试LLDPE老化前后的弯曲强度、拉伸强度,并利用红外光谱分析其表面化学性质的变化,评估了LLDPE的耐热氧老化性能。Artificial accelerated thermal aging experiments on the Polyethylene( LLDPE) used as rotational packaging case were maked under different temperature. The instron flexural strength and instron tensile strength before and after aging changes were tested. The changes of surface chemical property were analysised by FTIR. The thermal ageing resistance of Polyethylene( LLDPE) was evaluated.
