摘　　要：采用双辊开炼机和平板高压制样的方法制备了超细CaCO3/SBS复合材料,采用SEM、DSC和TG对复合材料的断面形貌和热性能进行了分析,同时,对复合材料的力学性能进行了考察。结果表明,表面处理的超细CaCO3在SBS体系中与弹性体充分结合,断面产生了大量的网状结构,进一步提高了材料的拉伸强度、断裂伸长率和热稳定性,硬度增加幅度较小。Ultra fine CaCO3/SBS composite was prepared by the two-roll mill and pressed plate,The fracture surface and thermal properties of the composite were analyzed by SEM,DSC and TG,and the mechanical properties were studied.The results showed that the ultra fine CaCO3 was treated can fully integrate with elastomer in SBS.The fracture surface appeared a lot of network structures.and the structures did some help to improve tensile strength,elongation at break and thermal stability,and the hardness was increased lesser extent.
