| 摘 要： | 以马来酸酐接枝(苯乙烯/乙烯/丁烯/苯乙烯)共聚物(SEBS-g-MAH)为增韧剂制备出了一系列超韧尼龙(PA)1111/SEBS-g-MAH共混体系,并对其力学性能和微观结构进行了研究.结果表明,随着增韧剂含量的增加,共混体系的缺口冲击强度显著提高,当增韧剂质量分数为25%时,缺口冲击强度为39.4 kJ/m<'2>,是纯PA1111的11.3倍.微观结构研究表明,PA1111的断裂属于韧性断裂,PA1111/sEBs-g-MAH共混体系的缺口冲击断面有明显的应力发白现象,冲击强度提高的主要原因在于应力集中点的增多而引发大量银纹所致.

| Abstract: | Flesibilizer SEBS-g-MAH was used to prepare the system of PA1111/SEBS-g-MAH,and the mechanical and microcosmic properties were studied.The result indicated that the notched izod impact strength enhanced obviously with the increase of toughening agent.When the content of SEBS-g-MAH was up to 25%,the notched izod impact strength is 39.4 kJ/m2,which is 11.3 times of that of pure PA1111.Microstructure showed that the fracture of PA1111 belonged to ductile.There was the phenomenon of stress whitening on the cros... |
