| 中文摘要: |
| 试验设计一种白炭黑补强溶聚丁苯橡胶的开炼机混炼工艺。相对于传统三段混炼工艺中的二段在高温开炼机上进行，将一段胶的热处理（硅烷化反应）放在老化箱中进行，重点考察热处理时间对胶料性能的影响。结果表明，该混炼工艺安全易行，二段热处理温度和时间控制精准，避免了高温混炼对胶料的剪切破坏，所得胶料的性能与密炼机混炼效果相当。 |
| 英文摘要: |
| A mill mixing technology of solution-polymerized styrene-butadiene rubber reinforced with silica was designed and investigated experimentally.The heat treatment of first-stage mix （i.e.silylation reaction） was carried out in the ageing oven rather than on high temperature mill in traditional three-step mixing process.The effect of the heat treatment time on property of the compound was studied.The results showed that， this mixing technology was a safe and effective process，in which the time and temperature of heat treatment could be precisely controlled，while the shear breakdown of the compound because of mixing at high temperature was avoided.The properties of the obtained vulcanizates were comparable to that using internal mixer. |
