摘　　要：采用偶联剂Si69对硼酸镁晶须进行改性,制备改性硼酸镁晶须/丁苯橡胶(SBR)复合材料,并对其性能进行研究。结果表明:硼酸镁晶须的加入使复合材料的物理性能和耐磨性能均有不同程度的提高;与未改性硼酸镁晶须相比,加入改性硼酸镁晶须的复合材料的物理性能较好。硼酸镁晶须能够显著提高复合材料的耐磨性能;与未改性硼酸镁晶须相比,加入改性硼酸镁晶须的SBR复合材料的耐磨性能较好。The magnesium borate whisker was modified by coupling agent Si69,and the modified magnesium borate whisker/SBR composites were prepared. The properties of composites were investi- gated. The results showed that, the physical properties and wear resistance of composites were im- proved when the magnesium borate whisker was used. Compared with those filled with unmodified magnesium borate whisker,the physical properties and wear resistance of composites filled with modi- fied magnesium borate whisker were better.
