摘要:
通过双螺杆挤出机制备出PA6/PP/PP g MAH(聚酰胺6/聚丙烯/马来酸酐接枝聚丙烯)复合材料,并以PA6/PP/PP g MAH为原料,使用化学发泡剂在双螺杆挤出机上制得PA6/PP/PP g MAH发泡材料。利用差示扫描量热仪(DSC)和热场发射扫描电镜(FESEM)研究了PP g MAH对PA6/PP/PP g MAH中PA6相非等温结晶性能和可发泡性能的影响。研究结果表明:PP g MAH的加入对PA6相的熔融行为并没有显著的影响,但却使其结晶温度略有下降;PP g MAH的加入并没有改变PA6相晶体的成核方式及生长机理,但能使晶体生长速率有不同程度的下降,PA6相的非等温结晶动力学始终符合Jeziorny和莫志深模型;PA6/PP/PP g MAH发泡材料的发泡倍率和泡孔直径随着PP g MAH含量的增加而逐渐减小,但其泡孔密度随着PP g MAH含量的增加先增加后降低;在实验范围内,当PP g MAH含量为5 phr时,PA6/PP/PP g MAH的可发泡性能最好。
