| 摘 要： | 制备了改性纳米CaCOa／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。分散在丙烯腈一丁二烯一苯乙烯共聚物(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／m^2,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％。

| Abstract: | The nano-CaCO_3/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 CaCO_3 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-CaCO_3 Particles. As compared with the pure ABS resin material, the single-notched impact strength of the ABS composites reachs( 36.77) kJ/m~2, 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. |
