| 中文摘要: |
| 研究硫化剂HMDC和促进剂DPG对乙烯-丙烯酸酯橡胶（AEM）性能的影响。结果表明：促进剂DGP用量一定（3份）时，随着硫化剂HMDC用量增大，混炼胶的硫化速率减小，硫化胶的交联密度和拉伸强度增大，耐热空气老化性能提高，耐低温性能降低；硫化剂HMDC用量一定（1份）时，随着促进剂DPG用量增大，混炼胶的硫化速率增大，硫化胶的交联密度减小，拉断伸长率和撕裂强度增大，耐热空气老化性能降低，耐低温性能提高。 |
| 英文摘要: |
| In this study，curing agent HMDC and accelerator DPG were applied in ethylene-acrylate rubber（AEM） and the properties of the compound were investigated.The results showed that with 3 phr accelerator DGP amount，when the curing agent HMDC amount increased，the curing rate decreased，the crosslink density and tensile strength of the vulcanized rubber increased，hot air aging resistance was improved and low temperature resistance was reduced.When the curing agent HMDC amount was fixed at 1 phr and the accelerator DPG amount increased，the curing rate increased，the crosslink density of the vulcanized rubber was reduced，elongation at break and tear strength increased，hot air aging resistance was reduced and low temperature resistance was improved. |
