摘　　要：采用差示扫描量热(DSC)和动态力学分析等方法研究物理老化对氟橡胶F_(2314)性能的影响。结果表明:在45℃下进行物理老化,随着物理老化时间的延长,氟橡胶F_(2314)的储能模量增大,损耗因子减小;DSC吸收峰的热焓没有明显变化,但峰位向高温方向移动;松弛模量增大,且增幅逐渐增大。The physical aging of fluoropolymer F2314 was studied by differential scanning calorime- try （DSC） and dynamic mechanical analysis. The results showed that,as the time of physical aging at 45℃ prolonged,the storage modulus of F2314 increased, the loss factor was decreased;the enthalpy of DSC absorption peak had no significant change,but the peak position moved towards higher tempera- ture zone;the relaxation modulus increased and the amplitude increased gradually.
