摘要
Abstract
Different antioxidant systems were used to modify polypropylene (PP) as anti-aging aids, the thermal gravimetric analysis (TGA) were used to characterize the effects of antioxidant systems on thermal stability of the PP, and also be used to characterize the effect on mechanical properties and melt index.The results showed that the thermal aging properties of PP could be improved by antioxidant system 3#(m(PP)∶m(1010)∶m(168)=100∶0.2∶0.4) at 150 ℃ compared with the other systems.The maximum tensile strength was 34.69 MPa after thermal oxidation of 400 h, and the lowest melt index was 1.74 g of every 10 min and the initial degradation temperature was as high as 323.46 ℃关键词
