The effects of N-isopropyl-N′-phenyl-phenylenediamine (4010NA) content on the damping and aging properties of hydrogenated nitrile butadiene rubber (HNBR)/nitrile butadiene rubber (NBR) (abbreviated as H-NBR) matrix are studied via molecular simulation and experiments. The effects of 4010NA addition on the damping and aging properties of H-NBR are analyzed by molecular simulation using solubility parameters (δ), hydrogen bonds, free volume fraction (FFV), binding energy (E_binding), hydrogen bond dissociation energy (ΔG), and mean square displacement (MSD). The damping, mechanical, and thermo-oxygen aging properties of the 4010NA/H-NBR composites are studied experimentally using infrared (FTIR) spectroscopy, X-ray diffraction (XRD), differential scanning calorimetry (DSC), and dynamic mechanical analysis (DMA). The results indicate that 4010NA has good compatibility with HNBR and NBR, and the addition of 4010NA can effectively improve the damping properties of H-NBR. When 4010NA is added at 32 phr, the composite has better damping properties, mechanical properties, and aging resistance, which provides a new insight for the construction of high performance elastomer composites.

4010NA/氢化丁腈橡胶/丁腈橡胶复合材料阻尼老化性能的分子模拟与实验研究

分子生物学研究了N-异丙基-N'-苯基苯二胺（4010NA）含量对氢化丁腈橡胶（HNBR）/丁腈橡胶（NBR）（简称H-NBR）基体阻尼老化性能的影响模拟和实验。利用溶解度参数（δ）、氢键、自由体积分数（FFV）、结合能（E _binding）、氢键解离能（ΔG ），通过分子模拟分析了4010NA的添加对H-NBR阻尼和老化性能的影响), 和均方位移 (MSD)。使用红外 (FTIR) 光谱、X 射线衍射 (XRD)、差示扫描量热法 (DSC) 和动态力学分析 (DMA) 对 4010NA/H-NBR 复合材料的阻尼、机械和热氧老化性能进行了实验研究). 结果表明4010NA与HNBR和NBR具有良好的相容性，添加4010NA可以有效提高H-NBR的阻尼性能。当4010NA添加量为32份时，复合材料具有更好的阻尼性能、力学性能和耐老化性能，为高性能弹性体复合材料的构建提供了新的思路。
