【摘要】 制备了改性纳米CaCO3/ABS复合材料,采用SEM和TEM对复合材料的微观结构进行了分析,同时,对复合材料的力学性能进行了考察。结果表明,改性纳米CaCO3可以在ABS塑料中与树脂充分结合,同时改性纳米CaCO3在复合材料中呈纳米分散。复合材料的断面产生了大量的网状结构。分散在丙烯腈-丁二烯-苯乙烯共聚物(ABS)中的改性纳米CaCO3可提高复合材料的裂缝引发能和裂缝增长能。其单缺口冲击强度达到36.77kJ/m2,与未添加纳米CaCO3的相比提高了44%;邵氏硬度达到34.87N,提高了23.5%。更多还原

【Abstract】 The nano-CaCO₃/ABS composites were produced. The microstructure of the composite was analyzed by using the SEM and TEM, and the mechanical properties were studied. The results show that the modificated CaCO₃ nanoparticles are well-dispersed in ABS resin at nano-scale. The microstructure of composites and fracture section further confirm that the properties are improved by the addition of modificated nano-CaCO₃ Particles. As compared with the pure ABS resin material, the single-notched impact strength of the ABS composites reachs（ 36.77） kJ/m², which has been increased up to 44%, while the rigidity of the composites has also been enhanced by（ 23.5%） which is （34.87） N.更多还原
