TPU/PVC/改性纳米碳酸钙复合材料力学性能研究

摘要

采用热塑性聚氨酯(TPU)、聚氯乙烯(PVC)以及碳酸钙制备了TPU/PVC/改性纳米碳酸钙复合材料.实验结果表明:TPU和PVC的最佳配料比为70/30、纳米碳酸钙含量为20份时对复合体系补强作用最佳.%TPU/PVC/modified nano calcium carbonate was prepared by using polyurethane (PU),polyvinyl chloride (PVC),and calcium carbonate.The experimental results showed that when the optimal mass ratio of PU and PVC is 70/30 and the content of nano calcium carbonate is 20 phr,the reinforced effect of it is best.
