| 中文摘要: |
| 对胶料混炼过程中不溶性硫黄（IS）熔融与分解协调控制进行研究。通过差式扫描量热分析得出IS的熔融速率最快温度为124.0 ℃，分解速率最快温度为132.9 ℃；采用HAAKE转矩流变仪对胶料混炼过程进行模拟，得出流变仪内壁温度（起始混炼温度）为90～95 ℃时，天然橡胶/IS共混胶中的IS既不分解，又能实现良好分散。 |
| 英文摘要: |
| The coordinated control of melting recation and decomposing recation of insoluble sulfur（IS） during the compound mixing was studied.The result of DSC analysis showed that the fastest melting rate of IS was 124.0 ℃，and the fastest decomposing rate of sulfur was 132.9 ℃.The HAAKE rheology instrument was used to simulate the compound mixing process.When in wall of the rheology instrument（temperature at mixing start） was 90～95 °C，IS of natural rubber/IS blend did not decompose，and was dispersed very well. |
