| 中文摘要: |
| 以过氧化二异丙苯（DCP）为硫化剂，制备环氧化天然橡胶（ENR）/丁腈橡胶（NBR）并用胶，并对其性能进行研究。结果表明：ENR/NBR并用比和硫化剂DCP用量对ENR/NBR胶料的焦烧时间和硫化速度影响不大；当硫化剂DCP用量为3份、ENR/NBR并用比为5/95～15/85时，ENR/NBR硫化胶的物理性能比NBR硫化胶有一定提高；当ENR/NBR并用比为20/80、硫化剂DCP用量为2份时，ENR/NBR硫化胶的拉伸强度和拉断伸长率最大；滞后损失分析得出ENR/NBR硫化胶在拉伸过程中消耗了更多能量。 |
| 英文摘要: |
| The epoxidized natural rubber（ENR）/nitrile rubber（NBR） blends were prepared using
dicumyl peroxide（DCP） as a curing agent，and their properties were studied. The results showed that the
ENR/NBR blending ratio and the curing agent DCP dosage had little effect on the scorching time and curing
rate of ENR/NBR compound. When the curing agent DCP dosage was 3 phr and the ENR/NBR blending
ratio was 5/95～15/85，the physical properties of ENR/NBR vulcanizate were slightly improved compared
to NBR vulcanizate. When the ENR/NBR blending ratio was 20/80 and the curing agent DCP dosage was
2 phr，the tensile strength and elongation at break of ENR/NBR vulcanizate were the largest. The hysteresis
loss analysis revealed that the ENR/NBR vulcanizate consumed more energy during the stretching process. |
