| 中文摘要: |
| 研究受阻酚AO-60用量对受阻酚AO-60/天然橡胶（NR）复合材料的结构与阻尼性能的影响。结果表明：受阻酚AO-60用量小于50份时，受阻酚AO-60在复合材料中主要形成小型聚集体；随着受阻酚AO-60用量的增大，受阻酚AO-60在复合材料中形成越来越多的大型聚集体；在差示扫描量热分析中，受阻酚AO-60在48和107 ℃下分别发生无定形态以及晶态转变；在室温下，受阻酚AO-60用量不小于50份的复合材料的tanδ达到0.2以上，而不加受阻酚AO-60的NR胶料的tanδ仅为0.05；随着受阻酚AO-60用量的增大，复合材料的Fmax－FL减小，t10和t90明显延长，拉伸强度和撕裂强度减小，受阻酚AO-60用量为50份的复合材料的回弹值最小。综合来看，受阻酚AO-60用量为50份的受阻酚AO-60/NR复合材料的性能最佳。 |

| The effect of hindered phenolic AO-60 amounts on the structures and damping properties of hindered phenol AO-60/natural rubber（NR） composites were studied.The results showed that，when hindered phenol AO-60 amount was no more than 50 phr，hindered phenol AO-60 formed small aggregates in the composites.As hindered phenol AO-60 amount increased，more and more large aggregates of hindered phenel AO-60 formed.In different scanning calorimetry analysis，hindered phenol AO-60 underwent amorphous and crystalline transitions at 48 and 107 ℃，respectively.At room temperature，the tanδ of the composites with no more than 50 phr hindered phenol AO-60 reached 0.2 or more，while the tanδ of NRcompound without hindered phenol AO-60 was 0.05.As hindered phenol AO-60 amount increased，the Fmax FLof the composites decreasede，the t10 and t90 were significantly prolonged，the tensile strength and tear strength decreased，and the rebound value was the smallest of the composite with 50 phr hindered phenol AO-60 amount.Overall，when hindered phenolic AO-60 amount was 50 phr，the hindered phenol AO-60/NR composite had the best properties. |
