| 摘 要： | 采用双螺杆挤出机液体进料熔融接枝制备了丙烯酸接枝聚丙烯(PP-g-AA),研究了聚丙烯(PP)/碳酸钙(CaCO3)/PP-g-AA复合材料的力学性能,并采用红外光谱、差示扫描量热仪、扫描电子显微镜等对复合材料进行了表征分析。结果表明,用此PP-g-AA作为PP/CaCO3的相容剂时,能有效提高其力学性能,且当CaCO3的含量为10%(质量分数,下同),接枝率为2.204%的PP-g-AA的含量为10%时,效果最佳。

| Abstract: | Acrylic acid grafted polypropylene(PP-g-AA) was prepared via melt grafting using a two screw extruder equipped with a liquid feeding,which was used as a compstibilizer in PP/CaCO3 system.The resulted system was studied using Fourier transform infrared spectroscopy(FTIR),differential scanning calorimetery(DSC),and scanning electron microscope(SEM).When content of CaCO3 was 10 % and content of PP-g-AA(grafting ratio 2.204 %) was 10 %,a set of optimal mechanical properties was obtained. |
