摘要
采用机械共混法制备碳化硅(SiC)/氟橡胶(FKM)复合材料,SiC添加前用偶联剂KH-560进行表面改性,研究改性SiC用量对SiC/FKM复合材料性能的影响。结果表明:随着改性SiC用量的增大,SiC/FKM复合材料的硬度增大,拉伸强度在一定范围内得到有效提升,阻尼性能和耐液体介质性能略有降低;当改性SiC用量为15份时,SiC/FKM复合材料具有良好的加工性能、物理性能、阻尼性能、热稳定性和耐液体介质性能,综合性能较优异。
In this study,Silicon carbide(SiC)was modified by coupling agent KH-560,the SiC/fluororubber(FKM)composites were prepared by mechanical blending,and the effect of the modified SiC amount on the properties of the SiC/FKM composites was studied.The results showed that,with the increase of the modified SiC amount,the shore A hardness of the SiC/FKM composites increased,the tensile strength was effectively improved within a certain range,while the damping property and liquid medium resistance were slightly reduced.When the modified SiC amount was 15 phr,the SiC/FKM composite had better processability,physical properties,damping property,thermal stability and liquid medium resistance,showingexcellent overall performance.
