| 中文摘要: |
| 研究普通硫化体系（CV硫化体系） 和平衡硫化体系（EC硫化体系） 对不同硫化温度下天然橡胶（NR） 性能的影响。结果表明： 与采用CV硫化体系NR胶料相比， 采用EC硫化体系NR胶料在143和150 ℃ 下都具有较低的硫化返原率；经长时间硫化后的EC硫化体系NR硫化胶具有更低的损耗因子； 提高硫化温度， EC硫化体系NR硫化胶的物理性能降幅更小；143 ℃ 时EC硫化体系NR硫化胶经热空气老化后的物理性能保持率更高。 |
| 英文摘要: |
| The effects of conventional vulcanization system（CV vulcanization system）and equilibrium vulcanization system（EC vulcanization system）on the properties of natural rubber（NR）at different vulcanization temperatures were studied.The results showed that，compared with the NR compound of CV vulcanization system，the EC vulcanization system NR compound had a lower vulcanization reversion rate at 143 and 150 ℃.After long time vulcanization，the EC vulcanization system NR vulcanizate had a lower loss factor.With the increase of the vulcanization temperature，the physical properties of the EC vulcanization system NR vulcanizate would decrease less.The physical properties retention rate of EC vulcanization system NR vulcanizate after hot air aging was higher. |
