    Microstructure and Property of Recycled Polyester Alloy Homogeneous Composite

    • 摘要: 由低温固相挤出工艺制备了连续废弃涤纶纺织品/回收聚对苯二甲酸乙二醇酯(r-PET)/高密度聚乙烯(HDPE)同质复合材料。采用扫描电子显微镜(SEM)、动态热机械分析仪(DMA)、差示扫描量热仪(DSC)、热重分析仪(TGA)、毛细管流变仪及万能电子拉力机等对含有不同编织结构的废弃涤纶纺织品复合材料微观结构和性能进行了研究。研究结果表明,线圈结构的废弃涤纶纺织品(F2)对复合材料结构与性能影响最显著。F2明显改善了HDPE在r-PET中的分散性,提高了复合材料的表观黏度、刚性以及热稳定性,并使得复合材料的拉伸强度、弯曲强度和弯曲模量分别提高了13.3%、28%和24%。

       

      Abstract: Polyester waste with recycled poly(ethylene terephthalate)/high density polyethylene (r-PET/HDPE) homogeneous composites were prepared by low temperature solid extrusion process.Microstructure and properties of the composites with different weave structures polyester waste were evaluated by analysis methods such as SEM,DMA,DSC,TGA,capillary rheometer,electromechanical universal tester and so on.Results indicate that the polyester waste with coil structure (F2) has a significant effect on the microstructure and performance of the composite materials in several kinds of polyester waste.The presence of F2improves the dispersion of HDPE in r-PET,enhances the viscosity,rigidity and thermal stability of composites,increases the tensile strength,bending strength and bending modulus by 13.3%,28% and 24%,respectively.
