摘　　要：以苯乙烯-乙烯-丁二烯-苯乙烯嵌段共聚物(SEBS)和聚丙烯(PP)为基体树脂,以纳米碳酸钙和普通重质碳酸钙为填充材料,在一定的工艺条件下用开炼机混炼。通过对SEBS/PP力学性能的测试及扫描电镜的比较,研究了纳米碳酸钙和普通重质碳酸钙对SEBS/PP共混料性能的影响及在基体中的分散情况。实验结果表明,纳米碳酸钙对共混物起到补强作用且其在共混物体系内呈纳米分散,随着纳米碳酸钙用量的增加,材料性能呈上升趋势,至12份时达到最大值。Based on the resin of styrene-ethylene-butadiene-styrene （SEBS） and polypropylene （PP） ,which used nano and common calcium carbonate as fillers,blends were mixed by mixing mill at definite technological conditions. The effect of nano or common calcium carbonate on SEBS/PP was researched through mechanic properties testing and SEM. The results showed that nano calcium carbonate was nano-dispersed and played a role of reinforcement. With the increasing content of the nano cal cium carbonate,the properties of blends were improved,and it showed the best property when nano calcium carbonate was added in 12wt%.
