通过在丁腈橡胶 NBR/受阻酚类抗氧化剂AO-2246共混物中填充不同形态填料(玻璃纤维和炭黑)，考察对其动态力学性能的影响。并通过动态力学性能分析仪、扫描电镜以及红外光谱等表征手段研究发现，分别填充两种不同类型填料于 NBR/AO-2246共混物中，杂化阻尼复合材料阻尼值均呈下降趋势。填充炭黑相比短纤维，具有较为优异的阻尼性能，且随着炭黑粒径的增大阻尼峰有被拓宽的趋势。结果表明，填料导致阻尼值下降主要归因于 NBR 与 AO-2246生产的分子间氢键逐渐消失；填充不同形态填料，杂化阻尼复合材料呈现不同阻尼特性，归因于材料内部形成不同内部微观结构，即在其内部形成了大量界面，使分子间运动呈现不同的滞后现象；而不同粒径炭黑对阻尼峰的影响，可从界面区数量得到解释。
The effect of the different configuration of fillers (glass fiber and carbon black)in the nitrile rubber (NBR)/small organic molecules (AO-2246)/blending on the dynamic mechanical properties have been investi-gated by using dynamic mechanical analyzer (DMA),scanning electron microscope (SEM)and Fourier trans-form infrared (FT-IR),etc.It was found that the damping peak values for the two different fillers both steady declined with the increase of the content.The NBR/AO-2246/carbon black (CB)blending showed the more ex-cellent damping property than that of NBR/AO-2246/short fibers blending.At meanwhile,there was a trend that the damping peak width may be broadened with the increment of particle sizes of CB.The results indicated that the decrease of damping value was owing to the disappearance of hydrogen bonds between the NBR and AO-2246 after added different fillersinto the NBR/AO-2246 blending.The hybrid damping materials filled with varied form of fillers which presented different internal microstructure was shown different damping characteris-tics,because a great deal of interfaces formed inside the material led to the phenomenon that molecule motions exhibited various hysteresis.The effect of different particle sizes of carbon black on the damping properties can be explained from the amount of interfaces.
