| 摘 要： | 以马来酸酐接枝线性低密度聚乙烯(MAH-g-LLDPE)为相容剂,回收聚对苯二甲酸乙二醇酯(rPET)为基体材料,茂金属线性低密度聚乙烯(mLLDPE)为增韧材料,制备rPET/mLLDPE塑料合金材料。采用DSC、SEM分析MAH-g-LLDPE对rPET/mLLDPE结晶性能及断面相结构的影响,测试了rPET/mLLDPE材料的流变性能及力学性能。结果表明,mLLDPE的加入使得rPET/mLLDPE熔体结晶峰向右移动,结晶温度提高;MAH-g-LLDPE的加入,共混体系中rPET的玻璃化转变温度(tg)朝低温方向移动,rPET与mLLDPE相容性增强,相界面模糊,界面黏结力强,熔融塑化过程扭矩值增大。含5%MAH-g-LLDPE的rPET/mLLDPE材料,与纯rPET相比,其结晶温度(tc)提高24.73℃,断裂伸长率提高113.6%,缺口冲击强度提高66.48%,柔韧性和抗冲击性能较大幅度提高。

| Abstract: | The rPET/mLLDPE plastic alloy material was prepared by using maleic anhydride grafted linear low density polyethylene(MAH-g-LLDPE) as compatibilizer, recovered polyethylene glycol terephthalexe (rPET) as matrix material, metalocenelinear low density polyethylene(mLLDPE) as toughening material. The effect of MAH-g-LLDPE on the crystal behavior and morphology of rPET/mLLDPE blends were investigated through DSC and SEM. The melt rheology and mechanical properties of rPET/mLLDPE blends were also studied. The cr... |
