采用模塑成型法制备了氰酸酯(CE)树脂/纳米碳化硅(nano-SiC)复合材料,通过磨损率、摩擦因数和扫描电镜(SEM)表征,探讨了经硅烷偶联剂表面处理过的nano-SiC对CE/nano-SiC复合材料摩擦性能的影响。研究结果表明:硅烷偶联剂对复合材料磨损率的影响大于对摩擦因数的影响;与未经硅烷偶联剂表面处理过的CE/nano-SiC复合材料相比,nano-SiC表面经硅烷偶联剂(如KH-560、SCA-3和SEA-171等)处理后,相应复合材料的磨损率降幅分别为51.52%、54.11%和55.84%,稳定摩擦因数降幅分别为5.94%、8.13%和12.19%;3种硅烷偶联剂中SEA-171的改性效果相对最好。
Cyanate (CE) resin / nano-SiC composites were prepared by molding method. The wear rate, friction coefficient and scanning electron microscopy (SEM) Of nano-SiC on the CE / nano-SiC composite friction properties. The results show that the effect of silane coupling agent on the wear rate of the composite is greater than that on the friction coefficient. Compared with the CE / nano-SiC composites without silane coupling agent surface treatment, The wear rates of composites decreased by 51.52%, 54.11% and 55.84%, respectively, and the stable friction coefficient decreased by 5.94%, 8.13% and 12.19%. The modification effect of SEA-171 in the three silane coupling agents is the best.
