摘要: 本论文用来研究橡胶粉改性沥青的机理。论文研究了在不同温度和不同时间下橡胶颗粒与催化油浆之间的相互作用。通过,对比催化油浆与橡胶颗粒作用前后催化油浆中的的四组份,得到四组份的变化规律。直接证据证明橡胶粉不仅吸收饱和分、芳香分还吸收胶质。在橡胶粉与沥青的作用中沥青质对脱硫降解有利。荧光纤维将照片证明了橡胶颗粒吸收了沥青中的某些组分使橡胶颗粒发生溶胀和在较高的温度下橡胶颗粒中的交联网络断裂。

Abstract: To investigate the mechanism of asphalt modification by crumb rubber, the interactions between FCC slurry and rubber particles were evaluated at different temperatures and time. The rules of the change in mass of SARA composition in FCC slurry were obtained before and after its interaction with rubber particles, which showed that crumb rubber not only absorbed saturates and aromatics but also resins. Asphaltenes promoted the desulfurization or degradation of crumb rubber during the interaction between asphalt and crumb rubber.
