| 中文摘要: |
| 制备水滑石（LDHs）/环氧化天然橡胶/丁苯橡胶气体阻隔复合材料，研究LDHs用量对复合材料的硫化特性、物理性能、动态力学性能、气密性和耐屈挠性能的影响。结果表明：随着LDHs用量增大，复合材料的t90缩短，拉伸强度呈增大趋势，储能模量在玻璃态变化不大，在高弹态呈增大趋势；与未添加LDHs的复合材料相比，添加LDHs的复合材料损耗因子在过渡区（0 ℃）减小，在高温区（60 ℃）增大；添加5份LDHs的复合材料气密性和耐屈挠性能较好。 |
| 英文摘要: |
| Layered double hydroxide compounds（LDHs）/epoxidized natural rubber（ENR）/styrene-butadiene rubber（SBR） gas barrier composites were prepared and the effect of the amount of LDHs on the curing characteristics，physical properties，dynamic mechanical properties，airtightness and flexural resistance of the composites was investigated.The results showed that，with the increasing of the amount of LDHs，t90 of the composites was shortened，the tensile strength had an increasing trend，and the storage modulus had little change in the glass state and increased in the high elastic state.Compared with the composites without LDHs，the loss factor of the composites with LDHs decreased in the transition zone（0 ℃），and increased in the high temperature zone（60 ℃）.The airtightness and flexural resistance of the composites with 5 phr LDHs were better. |
