摘要

摘要: 研究苯乙烯-丁二烯-苯乙烯嵌段共聚物（SBS）、马来酸酐接枝苯乙烯-丁二烯-苯乙烯嵌段共聚物（MAH-SBS）、纳米CaCO₃单独填加与复配填加对聚碳酸酯与丙烯腈-丁二烯-苯二烯三元共聚物（ABS）共混物（PC-ABS）性能的影响，采用电子扫描电镜观察其微观结构。结果发现，质量比PC：ABS=1：1时，共混材料综合性能最好；单独添加4wt%的纳米CaCO₃，PC-ABS的拉伸强度明显上升，冲击强度略有上升；单独添加SBS无法起到改良效果；单独添加MAH-SBS，MAH-SBS/PC-ABS的冲击强度上升，但拉伸强度严重下降；MAH-SBS与纳米CaCO₃复配时，可以起到协同作用，PC-ABS的冲击强度由80 kJ/m²上升至约108 kJ/m²，拉伸强度由57.0 MPa上升至约61.5 MPa。

Abstract: Effect of block copolymer of styrene and butadiene (SBS), maleic anhydride grafted SBS (MAH-SBS) and nano-CaCO₃ on PC-ABS blends properties were studied, and the micro structure was observed by SEM. It is found that when PC:ABS=1:1, the comprehensive properties of PC-ABS is the best; only 4wt% nano-CaCO₃ is added, the tensile strength of nano-CaCO₃/PC-ABS is increased obviously but the impact strength is increased slightly. It is invalid when SBS is used alone. If MAH-SBS is used alone, the impact strength of MAH-SBS/PC-ABS is increased but the tensile strength is decreased seriously. The mixture of MAH-SBS and nano-CaCO₃ have a synergistic effect, the impact strength is increased from 80 kJ/m² to about 108 kJ/m² and the tensile strength is improved from 57.0 MPa to about 61.5 MPa.
