| 摘 要： | 搅拌和超声条件下改性的纳米碳酸钙填充至聚氯乙烯(PVC),通过抗拉强度、断裂伸长率和冲击强度测试碳酸钙/PVC复合材料的机械性能.结果表明: PVC中纳米碳酸钙的最佳填充量是15 wt %,此时,纳米碳酸钙可均匀分散在PVC中,断裂伸长率和冲击强度明显增加,但抗拉强度略有下降;超声改性时,PVC/碳酸钙复合材料具有更好的抗冲击强度.

| Abstract: | The nano-CaCO3 was dispersed into PVC,which was modified under the condition of stirring or ultrasonic.The mechanical properties of PVC/CaCO3 composites were tested in aspects of tensile strength,elongation at break and impact strength.The results show that the optimum filling amount of nano-CaCO3 in PVC is 15 wt%.In this situation,nano-CaCO3 can be uniformly dispersed in PVC.The elongation at break and impact strength increase obviously,but tensile strength decreases slightly.The PVC/CaCO3 composites have the better impact strength when nano-CaCO3 is modified by ultrasonic. |
