| 中文摘要: |
| 研究受阻酚AO-60/IIR复合材料的结构与动态力学性能。结果表明，在受阻酚AO-60/IIR复合材料中，IIR为连续相，受阻酚AO-60为富集相，且穿插于IIR基体中，受阻酚AO-60分子间以及受阻酚AO-60分子与交联体系中的极性基团所形成的氢键使复合材料中形成了超分子网络结构。随着受阻酚AO-60用量的增大，IIR硫化胶的损耗因子（tanδ）峰逐渐向高温区移动，当受阻酚AO-60用量超过30份时，硫化胶的tanδ峰又移向低温区；在-35～-10 ℃温度范围内，IIR硫化胶的储能模量随受阻酚AO-60用量的增大而增大。 |

| The structure and dynamic properties of hindered phenol AO-60/IIR composite were investigated.The results showed that,IIR phase was continuous phase and hindered phenol AO-60 phase was dispersed phase in the composite.Super molecular network structure was formed by hydrogen bonding among AO-60/molecules,and between AO-60 molecule and other polar groups in the crosslinked IIR matrix.As the addition level of AO-60 increased,the tanδ peak of IIR vulcanizates moved to higher temperature zone,but started to move back to low temperature when the addition le-vel exceeded 30 phr.The storage modulus of IIR vulcanizate in the temperature range of -35～-10 ℃ increased as the addition level of AO-60 increased. |
