| 摘 要： | 对废聚氨酯（PU）改性聚氯乙烯（PVC）的性能进行了研究,探讨了废PU、热塑性聚氨酯（TPU）、轻质碳酸钙（CaCO3）和羟基磷酸钙Ca5（PO4）3OH]对PVC力学性能和耐溶剂性能的影响.实验结果表明,废PU使软质PVC的强度下降,伸长率提高,TPU可以提高软质PVC的强度和伸长率;废PU在PVC中起到大分子增塑剂的作用,用废PU取代增塑剂DOP不但可以大幅度提高PVC的强度,同时还提高了冲击强度和断裂伸长率;轻质CaCO3使废PU/PVC复合材料的撕裂强度下降,Ca5（PO4）3OH却可以使材料的撕裂强度提高.

| Abstract: | The properties of PVC modified by PU waste were reported in this paper. The influence on mechanical properties and solvent resistance of PVC modified by polyurethane waste,TPU,CaCO_3 and(Ca_5(PO_4)_3OH) were studied respectively.The result indicated that polyurethane waste decreased the strength of flexible PVC,and increased its elongation;TPU enhanced the strength and elongation of PVC. Polyurethane waste played a role as polymer plasticizer.Polyurethane waste substituting DOP not only enhanced the strength of PVC greatly,but also enhanced its impact strength and elongation.CaCO_3 decreased tearing strength of PU/PVC composites.Instead Ca_5(PO_4)_3OH improved tearing strength of the materials. |
