| 中文摘要: |
| 研究助交联剂HVA-2用量对过氧化物硫化氯磺化聚乙烯（CSM）胶管胶料性能的影响。结果表明：随着助交联剂HVA-2用量增大，混炼胶的Fmax增大，t10变化不大，t90缩短，交联密度增大；硫化胶的硬度和拉伸强度增大，拉断伸长率减小，压缩永久变形减小；老化后，硫化胶的硬度和拉伸强度增大，拉断伸长率减小，且变化幅度随着HVA-2用量增大而减小；油浸泡后，硫化胶的体积减小，且体积变化率随着助交联剂HVA-2用量增大而减小；当助交联剂HVA-2用量为2份时，硫化胶的综合性能较好。 |
| 英文摘要: |
| The effect of the amount of auxiliary crosslinking agent HVA-2 on the properties of peroxide cured chlorosulfonated polyethylene（CSM） hose compound was investigated. The results showed that，with the increase of auxiliary crosslinking agent HVA-2 amount，the Fmax of compound increased，t10 changed little，t90 was shortened，the crosslinking density increased. The hardness and tensile strength of vulcanizate increased，the elongation at break decreased，and the compression set decreased. After aging，the hardness and tensile strength of vulcanizate increased，the elongation at break decreased，and the range of change decreased with the increase of auxiliary crosslinking agent HVA-2 amount. After soaking in oil，the volume of vulcanizate decreased，and the volume change rate decreased with the increase of auxiliary crosslinking agent HVA-2 amount. When the amount of auxiliary crosslinking agent HVA-2 was 2 phr，the comprehensive properties of vulcanizate were better. |
