| 摘 要： | 制备了复合增韧改性剂聚丙烯酸酯/纳米CaCO3(PA-C),并将其用于硬质聚氯乙烯(PVC)中,以研究其增韧效果.使用扫描电子显微镜(SEM)观察了复合材料的微观结构,并测试了复合材料的力学性能.结果表明:PA-C均匀分散于PVC基体中;当在PVC中添加10份PA-C时,复合材料的缺口冲击强度达到88.2kJ/m2,冲击强度和弯曲模量明显增大,拉伸强度未明显降低;SEM照片显示PA-C有效地引发了PVC基体产生塑性形变,有利于能量的吸收.

| Abstract: | The polyacrylate/nano-CaCO3(PA-C)composite toughening hard PVC was successfully prepared and the toughening effect was researched.The effects of polyacrylate/nano-CaCO3 composite on the mechanical properties and micro-morphology of PVC were investigated by SEM.It was found that PA-C dispersed in PVC matrix uniformly.The addition of PA-C 10 phr in PVC could make the notched impact strength of composite reach to 88.2 kJ/m2,the impact strength and the flexure modulus increased obviously,led to a slight decreas... |
