| 中文摘要: |
| 以气相法白炭黑（用量为20，27和31份）作为补强填料，通过机械共混法制备耐磨耐油氟硅橡胶（FVMQ）复合材料（简称FVMQ胶料），研究气相法白炭黑用量对FVMQ胶料性能的影响。结果表明：当硫化剂DBPH用量为0.8份时，气相法白炭黑用量为31份的FVMQ胶料的Fmax和Fmax－FL最大；与气相法白炭黑用量为20和27份的FVMQ胶料相比，气相法白炭黑用量为31份的FVMQ胶料的邵尔A型硬度、100%定伸应力、300%定伸应力和拉伸强度较大，损耗因子最大值较小，摩擦因数最大；在15#航空液压油中浸泡（室温×27 h）后，气相法白炭黑用量为31份的FVMQ胶料的质量变化率和体积变化率最小，分别为1.5%和3.8%。综合来看，气相法白炭黑作为补强填料能够有效提高FVMQ胶料的物理性能、耐油性能和耐磨性能，气相法白炭黑补强FVMQ胶料在航空领域应用前景广阔。 |

| Wear resistance and oil resistance fluorinesilicone rubber（FVMQ） composites（referred to as FVMQ compounds） were prepared by mechanical mixing using 20，27 and 31 phr of fumed silica as reinforcing filler，and the effect of fumed silica dosages on properties of FVMQ compounds was studied.The results showed that when vulcanizing agent DBPH dosage was 0.8 phr，the Fmax and Fmax－FL of FVMQ compounds with 31 phr of fumed silica were the highest.Compared with FVMQ compounds with 20 and 27 phr of fumed silica，FVMQ compounds with 31 phr of fumed silica had higher Shore A hardness，modulus at 100%，modulus at 300%，and tensile strength，with a smaller maximum loss factor and the highest friction coefficient.After soaking in 15# aviation hydraulic oil （room temperature× 27 h），the FVMQ compound with 31 phr of fumed silica had the smallest mass change rate and volume change rate，which were 1.5% and 3.8%，respectively.Overall，using fumed silica as a reinforcing filler could effectively improve the physical properties，oil resistance and wear resistance of FVMQ compound.The application prospects of fumed silica reinforced FVMQ compounds in the aviation field were broad. |
