摘　　要：研究了采用自制新型混炼器对聚丙烯(PP)冲击性能的影响。结果表明:不加抗氧剂时,PP的冲击强度降低了27.3%;加入抗氧剂与不加抗氧剂相比,在混炼器转速为5r/min时,其冲击强度提高了45.5%。但无论是否加入抗氧剂对PP的拉伸强度影响不大。It has investigated that the self-made new-type mixer has influence on the PP＇s impact strength. The result showed that PP＇s impact strength decreased by 27.3% when without adding antioxidant; while adding antioxidant in, at mixer speed of 5r/min, PP＇s impact strength increases by 45.5%. However, to add antioxidant or not to the blends, it has very little effect on the tensile strength of PP.
