摘　　要：报道了在室温和70℃下橡胶材料G402氟硅胶、丁腈胶5171、丁腈胶4170、贮囊橡胶用合成的高密度燃料HDF 1浸泡后性能如伸长率、邵尔硬度、重量、面积体积的变化,并与采用3号喷气燃料(RP 3)实验结果进行对照。用红外光谱测定了燃料浸泡前后橡胶组成的变化。实验结果表明,G402氟硅胶和贮囊对于HDF 1和RP 3有相近的相容性,丁腈胶5171对HDF 1的相容性比对RP 3的相容性稍差,丁腈胶4170对HDF 1的相容性比对RP 3的相容性更差的结果。因此,丁腈胶5171和丁腈胶4170不能用于HDF 1储存和输送,原使用RP 3系统的橡胶密封件不能直接使用HDF 1。In the study of the application of high-density fuel HDF-1, the compatibility of rubbers used in the system with fuel HDF-1 is one of important issues because it directly affects the storage, transportation and use of fuel HDF-1 This paper reports the effects of fuel HDF-1 on the rubbers such as nitrile rubber 4170, nitrile rubber 5171, fluorinated silicone rubber G402 and container rubber at room temperature or 70?℃ and comparison of the results with No 3 jet fuel (RP-3) The rubbers were characterized by FTIR The results show that fluorinated silicone rubber G402 and container rubber are compatible with fuel HDF-1 and fuel RP-3 Fuel HDF-1 is less compatible with nitrile rubber 5171 than fuel RP-3, and fuel HDF-1 is least compatible with nitrile rubber 4170 Therefore, nitrile rubber 4170 and nitrile rubber 5171 are not suitable for the storage and transportation of fuel HDF-1, the rubbers used in the fuel RP-3 system cannot be directly used in the fuel HDF-1 system
