摘要(Abstract)：

丁腈橡胶是油浸式设备的主要密封材料之一，其性能直接影响设备的安全运行。以弹性应变能密度和硬度作为性能参数，结合红外光谱和拉伸断口特征等信息，分析丁腈橡胶在油浸环境中的结构变化，确定其传质行为与性能变化间的关系，以明确丁腈橡胶在油浸环境中的性能退化机理。结果表明，丁腈橡胶在油浸环境中出现溶胀，其弹性应变能密度和硬度明显下降，这两个指标与油浸参数有显著相关性；官能团氧化、油渗入和添加剂溶出等传质表现是导致其性能变化的重要原因。
Nitrile butadiene rubber(NBR) is a crucial sealing material for oil-immersed equipment, and its properties have a direct impact on the safe operation of equipment. With elastic strain energy density and hardness as the property parameters, the infrared spectra and tensile fracture characteristics are used to analyze the structural changes in NBR immersed in oil to determine the relationship between its mass-transfer behaviors and the property variations and elucidate the mechanism of property degradation. The findings reveal that NBR experiences swelling when immersed in oil, resulting in a significant reduction in both elastic strain energy density and hardness. These two indices exhibit a strong correlation with oil immersion parameters. Mass transfer behaviors, such as oxidization of functional groups, oil infiltration, and additive dissolution, emerge as the primary drivers behind the property change.
