| 中文摘要: |
| 研究硫化剂DCP和助交联剂TAC用量对氢化丁腈橡胶（HNBR）胶料性能的影响。结果表明：当助交联剂TAC用量为3份时，随着硫化剂DCP用量的增大，HNBR胶料的焦烧时间和正硫化时间缩短，硫化胶的物理性能提高，压缩永久变形明显减小，耐热氧老化性能有所改善；当硫化剂DCP用量为4份时，随着助交联剂TAC用量的增大，HNBR胶料的门尼粘度降低，硫化胶的定伸应力增大，压缩永久变形减小，耐热氧老化性能变化不大；硫化剂DCP和助交联剂TAC用量对HNBR硫化胶浸油后的物理性能有一定影响，但对体积膨胀率影响不大。 |
| 英文摘要: |
| The effects of the amounts of curing agent DCP and cocrosslinking agent TAC on the
properties of hydrogenated nitrile rubber（HNBR） compound were studied. The results showed that when
the amount of cocrosslinking agent TAC was 3 phr，with the increase of the amount of curing agent DCP，
the scorch time and optimal curing time of HNBR compound were shortened，the physical properties
of the vulcanizate were improved，the compression set was significantly reduced，and the heat-oxygen
aging resistance was improved. When the amount of curing agent DCP was 4 phr，with the increase of the
amount of cocrosslinking agent TAC，the Mooney viscosity of HNBR compound decreased，the modulus
of the vulcanizate increased，the compression set decreased，and the heat-oxygen aging resistance changed
little. The amounts of curing agent DCP and cocrosslinking agent TAC had a certain effect on the physical
properties of HNBR vulcanizate after oil immersion，but had little effect on the volume expansion rate. |
