| 中文摘要: |
| 采用低乙酸乙烯酯质量分数的乙烯-乙酸乙烯酯橡胶（EVM）制备吸油橡胶，考察硫化剂DCP用量、补强填料种类及用量对其吸油膨胀性能和物理性能的影响，并对其耐老化性能、饱和吸油后稳定性能和保油率进行研究。结果表明：当硫化剂DCP用量为1.5份时，EVM硫化胶的物理性能和吸油膨胀性能较好；与白炭黑填充的硫化胶相比，炭黑填充EVM硫化胶的吸油膨胀性能较优；EVM吸油膨胀材料在酸、碱、盐环境中具有优异的耐老化性能和稳定性能，且保油率高。 |
| 英文摘要: |
| The oil swellable rubber was prepared with EVM with low VA content and different reinforcing fillers.The influence of addition level of curing agent DCP and fillers on the swelling properties and physical properties was investigated，and the aging properties，performance stability after complete swelling and oil retention were studied.The results showed that，when the addition level of curing agent DCP was 1.5 phr，the physical properties and oil swelling rate of EVM vulcanizates were better.Compared with that filled with silica，the oil swelling property of vulcanizates filled with carbon black was better.The oil swellable EVM rubber showed good aging properties and stability in the acidic，alkaline and salty medium，and possessed higher oil retention. |
