| 摘 要： | SBS热塑性弹性体是目前世界上改性沥青用量最大的聚合物改性剂。但也存在某些不足,如改性沥青加工过程中的温度老化、贮存稳定性及在紫外线作用下降解加速材料老化等问题。用SBS的改性产物SBS-IP和SBS-TP改性沥青,可基本解决这些问题。着重介绍了用SBS-IP改性弹性体改性沥青的研究过程与改性机理。

| Abstract: | Therm o-plastic elastomer SBS is the biggest polymer modifier in the world used in bi tumen modification.However,some drawbacks exist,such as high temperature agi ng in process of modification,low storage stability and degradation acceleratio n under ultraviolet.The problems can be solved by using modified SBS,SBS-IP and SBS-TP.The article mainly introduces the study of bitumen modification wit h modified elastomer and the mechanism of modification. |
