摘要: 采用聚丙烯丙烯腈接枝共聚物(PPgAN)对聚丙烯(PP)进行抗老化改性,并通过加速老化测试仪、扫描电子显微镜、傅里叶红外光谱仪等仪器测试表征了老化后PP、PP/PPgAN的基团变化情况,并测试了加速老化500、1000、1500、2000和2500 h后纯PP和PP/PPgAN的力学性能。结果表明,PP/PPgAN经过加速老化后具有良好的抗老化性能,当PPgAN含量为7 %时,加速老化2500 h后PP/PPgAN的拉伸强度达到最大值19.87 MPa,冲击强度最高达到60.46 kJ/m2。

Abstract: Polypropyleneacrylonitrile graft compolymer(PPgAN) was grafted onto polypropylene. Aging resistance of PP/PPgAN was studied using SEM and FTIR. QUV was used to speedup aging of the materials for 500, 1000, 1500, 2000, and 2500 h. It showed that PP/PPgAN had an improved aging resistance. When the PPgAN content was 7 %, the tensile strength of modified materials reached a maximum of 19.87 MPa and an impact strength of 60.46 kJ/m2 after accelerated aging 2500 h.
