摘要
用示差扫描量热仪 (DSC)从能量变化的角度研究 SBS、SBS- g- MAH改性沥青的热储存稳定性 ,同时借助 FT- IR、软化点对改性沥青体系进一步分析研究。结果表明 ,由于 SBS- g- MAH的极性比 SBS高 ,与沥青之间能形成一种更稳定的、均匀的、分相而不分离的织态结构 。
In this paper hot storage stability of SBS, SBS-g-MAH Modified asphalt system was studied by DSC. Further study on hot storage stability of SBS, SBS-g-MAH modified asphalt system was analyzed by FT-IR, softening point measurement. The results indicate that because SBS-g-MAH has the higher polarity than SBS, it can be mixed with asphalt to form a more stable structure with phase separation but not segregation. Therefore, SBS-g-MAH can effectively improve the hot storage stability of modified asphalt.
