摘　　要：聚丙烯(PP)在汽车制造、医药包装、电器及日用品等领域都有着较为广泛的应用。但由于光、热、氧气的存在,PP易被氧化而发生粉化、脆化、黄变等老化行为,从而导致制品的性能下降,添加抗氧剂可以有效的对抗PP的热氧老化。因此综述了PP体系的不同类型抗氧剂,分析了不同抗氧剂体系的性能差异及其复配应用效果,并提出对未来PP抗氧剂研究的相关见解。Polypropylene(PP)has a wide range of applications in automotive manufacturing,pharmaceutical packaging,electrical appliances and daily necessities.However,due to the existence of light,heat and oxygen,PP is easy to be oxidized and aging behaviors such as powder,embrittlement and yellowing occur,resulting in a decline in the performance of the product.The addition of antioxidants can effectively combat the thermal and oxygen aging of PP.Therefore,this paper reviewed the different types of antioxidants in PP systems,analyzed the performance differences of different antioxidant systems and their compound application effects,and put forward relevant insights for future research on PP antioxidants.
