| 摘 要： | 研究了改性纳米CaCO3对ABS／PVC共混体系力学性能和吸水率的影响。结果表明，在ABS／PVC共混体系中加入纳米CaCO3可以提高体系的冲击强度和表面硬度，提高最大幅度分别为25．2％和10.5％，随着改性纳米CaCO3添加量的增加，冲击强度先增加后下降，表面硬度有所增加，吸水率有所下降。通过SEM和TEM分析表明，纳米CaCO3呈纳米分散，且与塑料基体结合良好。

| Abstract: | The effects of modified nano-CaCO3 on mechanical performance and water absorption percentage of ABS/PVC blend were studied. The experimental results indicate that nano-CaCO3 can enhance impact strength and surface rigidity of ABS/PVC blend up to 25.2% and 10.5% respectively. With increasing nano-CaCO3 contents, impact strength rises to a peak followed by a gradual reduction, while surface rigidity increases and water absorption percentage decreases. SEM and TEM analyses exhibit that nano-CaCO3 disperses at a nanosized state in the matrix and has a good compatibility with the resin. |
