摘　　要：用单螺杆挤出机制备了纳米CaCO3/SBS共混物。分别采用了纳米CaCO3(粉料)和纳米CaCO3母料。结果表明。直接添加纳米CaCO3(粉料)对SBS的补强效果十分有限,纳米CaCO3母料的加入可以改善增强效果。研究了纳米CaCO3母料的添加量对共混物流变性能和耐磨性能的影响,并通过SEM和TEM观察了纳米CaCO3粒子的分散状况。Nano-CaCO3 （powder）/SBS and Nano-CaCO3 masterbatch/SBS blends were prepared by single screw extruder. The results showed that nano-CaCO3 （powder）had limited effect on the reinforcement of SBS and nano-CaCO3 masterbatch was much more effective. The rheological property and wear resistance of nano-CaCO3 master batch/SBS blends were tested. By means of SEM and TEM,the dispersion effect of nano-CaCO3 had also been investigated.
