| 摘 要： | 通过原位微纤化技术和反应增容,制备了含回收聚对苯二甲酸乙二醇酯(PET)、低密度聚乙烯(LDPE)和线性低密度聚乙烯(LLDPE)以及高密度聚乙烯(HDPE)的原位微纤化共混物(MRB).探讨了原位成纤作用下,相容剂马来酸酐接枝聚乙烯(PE-g-MAH)用量对共混物力学性能的影响,同时利用差示扫描量热仪(DSC)和扫描电镜(SEM)研究了含4份PE-g-MAH共混物的非等温结晶特性和共混物形态.结果表明,成纤和增容双重作用对共混物的拉伸强度、断裂伸长率、弯曲模量和弯曲强度都有提高,而冲击强度有所下降；微纤对基体聚乙烯结晶有促进作用且注塑共混物比拉伸共混物更明显.HDPE与LLDPE发生了共结晶；拉伸共混物中的微纤比注塑共混物中的微纤长.

| Abstract: | In-situ Microfibrillar Blends(MRB) of recycled PET,LDPE,LLDPE and HDPE were fabricated by both in-situ microfibrillar technology and reactive compatibilization.The effects of the content of compatibilizer PE-g-MAH on the mechanical properties of blends by in situ microfibrillar methods were investigated.Meanwhile,the non-isothermal crystallization and morphology of containing 4 phr PE-g-MAH blends were studied by DSC and SEM.The results show that tensile strength,elongation at break,flexural modulus and str... |
