| 中文摘要: |
| 采用甲基丙烯酸六氟丁酯-甲基丙烯酸甲酯-甲基丙烯酸缩水甘油酯三元共聚物对纳米氮化硅进行表面改性，制备改性纳米氮化硅/氟橡胶（FKM）复合材料，并对其性能进行研究。结果表明：改性纳米氮化硅在FKM基体中分散均匀；当改性纳米氮化硅用量为1.5份时，改性纳米氮化硅/FKM复合材料的综合物理性能、耐磨性能、耐热空气老化性能和耐油性能较好。 |
| 英文摘要: |
| The nano-silicon nitride was modified by hexafluorobutyl mathacrylate-methyl methacrylate-glycidyl methacrylate terpolymer，the modified nano-silicon nitride/FKM composite was prepared，and its properties were investigated.The results showed that，the modified nano-silicon nitride was uniformly dispersed in FKM matrix；when the addition level of modified nano-silicon nitride was 1.5 phr，the composite possessed better comprehensive physical properties，wear resistance，thermal aging property and oil resistance. |
