摘要
综述了不同极性聚合物材料共混界面的相容性、改善相容性的方法以及增容技术的应用,重点介绍了利用第3组分增容双组分(聚丙烯/聚氯乙烯)和多组分混杂废旧异性塑料共混物的混容技术。对通过粉碎技术、注挤法成型、挤出成型、模压成型、注射成型等5种加工方法获得高附加值制品的加工工艺及相关设备的研究现状做了介绍。此外,对如何进一步开展不分类废旧塑料的再生利用提出了一些建议。
The preparation and compatibilization technique of immiscible polymer blends from plastics wastes were reviewed in this paper. The blending technologies including grinding, extrusion, injection, and compression moldings and the related equipments were introduced. The compatibilization of PP/ PVC blends by introducing a third component was discussed in detail. Some suggestions were made for the development of the recovery and utilization of commingled waste plastics.
