摘要

为利用废弃PET（r-PET）发展r-PET/PP共混物，该文制备了不同r-PET/相容剂、r-PET/PP和PP-g-MA及其混合相容剂增容r-PET/PP共混物，研究了以上共混物的拉伸、弯曲和冲击性能，讨论了不同相容剂对r-PET力学性能，r-PET对PP力学性能和增容共混物力学性能的影响。结果表明相容剂加入降低r-PET力学性能，r-PET提高PP拉伸和弯曲性能，r-PET/PP共混物的拉伸和弯曲性能随r-PET用量增加而提高，表明r-PET对PP中具有增强作用。PP-g-MA加入提高r-PET/PP共混物拉伸和弯曲性能，POE-g-MA和EVA-g-MA加入提高PP-g-MA增容r-PET/PP共混物冲击强度，采用混杂相容剂可获得综合性能优良的r-PET/PP共混物。

Abstract

In order to develop PP blends with recycled polyethylene terephthalate (r-PET)

the blends of r-PET with compatibilizer

r-PET/PP and compatibilized r-PET/PP blends were prepared. PP-g-MA and its mixture of POE-g-MA or EVA-g-MA with same functional group were used as compatibilizers. The tensile strength

flexural strength and modulus and impact strength of blends were characterized. The effect of compatibilizer and r-PET on mechanical properties of blends was studied. The results indicated that the mechanical properties of r-PET decreased by adding compatibilizer. But the tensile strength

flexural strength and modulus of iPP increased by introduction of r-PET

and the mechanical properties of r-PET/iPP blends increased by adding compatibilization of PP-g-MA further. The increased mechanical properties of uncompatibilized and compatibilized r-PET/iPP blends with increasing r-PET contents indicated the presence of reinforcement of r-PET in the iPP matrix. The r-PET/iPP blends with high strength and high toughness could be obtained by compatibilization of mixture of compatibilizers. Addition of POE-g-MA or EVA-g-MA increased the impact strength of PP-g-MA compatibilized r-PET/PP blends. The r-PET/PP blends with high performance could be obtained by compatibilization of mixture PP-g-MA and POE-g-MA.
