摘要
采用机械共混的方法，将聚氯乙烯树脂及其助剂进行高速混合，然后与热塑性聚氨酯弹性体熔融共混。测试其拉伸性能及流变性能，确定共混的工艺条件和加工条件。综合试验的结果，找出增韧改性较好的最佳合金配比。另外，在聚合物中加入少量的ＣａＣＯ３，既降低了成本。
s PVC resin and additives were mixed by means of mechanical blending and then melting blended with thermal plastic PU elastomer.By the determination of the tensile strength and rheological properties of the PVC/PU blend,the technology for blending and processing was propsed,and the optimum blend ratio for the blend was abtained from an overall test.In addition,the adding of CaCO3 to the blend not only lowered the cost,but also improve the mechanical properties of the blend.
