中海36-1 AH-90沥青的SBS改性

SBS Modification on Zhonghai 36-1 AH-90 Asphalt

对中海36-1原油生产出的AH-90沥青进行SBS改性要在190℃左右温度下进行 生产。随着改性剂的增加,改性沥青针入度降低,软化点升高,PI提高;稳定剂对改性沥青 软化点、粘度等指标有较大影响,要选用适合的稳定剂添加量;相容剂对改性沥青针入度、低 温延度有较大影响,要选用合适的相容剂添加量。

SBS modification on AH-90 Asphalt from Zhonghai 36-1 must be carried on production under higher temperature （about 190℃） . Along with the modifier increasing, the penetration degree of the modified asphalt reduces, the softening point elevates and PI index enhances ; The stabilizer has a more tremendous influence on the modified asphalt softening point, viscosity and so on, so we must select suitable stabilizer dosage. As well as the compatibilizer has a more tremendous influence on penetration degree and the low temperature ductility, so we must also select appropriate compatibilizer dosage.
