- 摘要:
- 将沥青按极性分离为饱和分、芳香分、胶质和沥青质四组分，考察四组分对顺丁橡胶（BR）硫化过程和硫化效果的影响。结果表明，沥青中的饱和分和芳香分能够延长BR的焦烧时间，提高加工安全性；胶质和沥青质可有效提高胶料的最大转矩，加快硫化速率；沥青则延长了BR的焦烧时间并加快了胶料的硫化速率，但可小幅降低最大转矩；胶质和沥青质中富含的氧、氮及硫官能团可有效参与BR的硫化反应。
- Abstract:
- Asphalt was separated into 4 components, saturated, aromatic, resin and asphaltene, according to its polarity. The effect of the 4 components on the vulcanization process and vulcanization effect of cis-1,4-polybutadiene rubber (BR) were investigated. The results showed that the saturated and aromatic components in asphalt could prolong the scorch time of BR and improve the processing safety. Resin and asphaltene could effectively increase the maximum torque of compound and accelerate the curing rate. Asphalt prolonged the scorch time and accelerated the curing rate of the BR compound, but it could slightly reduce the maximum torque. The oxygen, nitrogen, and sulfur functional groups which were rich in resins and asphaltenes could effectively participate in the vulcanization reaction of BR.
