| 中文摘要: |
| 研究不同硫化体系和混炼工艺对胶料玻璃化温度（Tg）的影响。结果表明：随着硫化剂用量的增大，多硫键和双硫键比例减小，单硫键比例增大，胶料的Tg明显上升；混炼时间较短时，胶料的Tg随混炼时间延长而下降；随着混炼时间的进一步延长，胶料的Tg有上升的趋势。 |
| 英文摘要: |
| The effects of different curing systems and mixing processes on the glass transition temperature（Tg） of rubber compound were investigated.The results showed that，with the increase of the amount of curing agent，the proportion of polysulfide bond and double sulfur bond decreased，the proportion of single sulfur bond increased，and the Tg of the compound was increased significantly.When the mixing time was short，the Tg of the compound was decreased with the extension of the mixing time.With the further extension of the mixing time，the Tg of the compound had an upward trend. |
