摘    要:利用熔融共混方法制备出纳米碳酸钙/回收丙烯腈-丁二烯-苯乙烯复合材料,采用偶联剂对纳米碳酸钙表面改性,或加入增容剂马来酸酐接枝(丙烯腈/苯乙烯)共聚物(AS-g-MAH),得到力学性能较好的纳米碳酸钙/回收丙烯腈-丁二烯-苯乙烯复合材料.研究了纳米碳酸钙含量、偶联剂、增容剂AS-g-MAH对回收丙烯腈-丁二烯-苯乙烯(ABS)力学性能的影响.实验结果表明:与新料ABS相比,回收的ABS性能有所下降.纳米碳酸钙含量为ABS质量的2%,硅烷偶联剂含量为纳米碳酸钙质量的5%,或增容剂AS-g-MAH为纳米碳酸钙质量的2%时,回收ABS的力学性能最佳.扫描电镜显示加入增容剂AS-g-MAH后,纳米碳酸钙粒子能均匀混合在回收ABS中,且粒径分布较窄,分散性好;无增容剂时有纳米碳酸钙团聚粒子出现.

关 键 词:回收丙烯腈-丁二烯-苯乙烯共聚物  纳米碳酸钙  性能  改性  增容

Abstract:The nano calcium carbonate/recycled acrylonitrile-butadiene-styrene copolymer composites were prepared by the melt blending,and they have better mechanical properties after the surface of nano calcium carbonate was modified by the coupling agent,or compatibilizer maleic anhydride grafted acrylonitrile styrene copolymer(AS-g-MAH)was added.Effects of the content of nano calcium,coupling agent,compatibilizer AS-g-MAH on the mechanical properties of recycled acrylonitrilebutadiene-styrene(ABS)were studied.Experimental results show that the performance of recycled ABS decreases compared with the new ABS materials;recycled ABS has optimal mechanical properties as the content of nano calcium is 2% of ABS quality,the content of silane coupling agent and AS-gMAH is 5%and 2% of nano calcium quality.Scanning electron microscopy shows that the addition of compatibilizer AS-g-MAH,nano calcium particles can be uniformly mixed in recycled ABS,and have narrow particle size distribution and good dispersion;nano calcium particles appear aggregation without the compatibilizer AS-g-MAH.
Keywords:recycled acrylonitrile-butadiene-styrene copolymer  nano calcium carbonate  property  modification  compatibility
