SBS作为典型的聚合物材料,可以通过红外光谱分析明确探知其在699cm-1处有苯环单取代吸收峰和966cm-1处有丁二烯反式振动吸收峰。目前,红外光谱法已成为SBS改性沥青中SBS检测分析的重要手段。李炜光等,孙大权等,采用实验室常规红外光谱仪上海11选5走势图,研究了基质沥青、SBS及SBS改性沥青的红外光谱特征,分析了SBS含量对SBS改性沥青特征吸收面积的影响。

 

对于同一物质、同一设备,ε和L为定值,c与A呈正比,因此对于相同的基质沥青和SBS改性剂制备的SBS改性沥青样品,当采用iCAN9傅立叶红外光谱分析仪进行红外光谱采集后,可以通过吸光度的变化,来鉴别改性沥青中SBS含量的变化幅度。李炜光等和孙大权等就是通过LAmBeRT-BeeR定律来进行改性沥青中SBS含量的检测。

(3)采用3种工艺制备SBS改性沥青,通过ATR-FTIR测试,可以明显看出3种制备工艺在1300-650cm-1波长范围内一组平行样的吸光度变化幅度明显不同,通过计算平行样在699cm-1处和966cm-1处的吸光度的标准偏差,并根据SBS中S段和B段的质量百分比,可以直接量化出改性沥青中SBS吸光度的标准偏差,进而量化出SBS在改性沥青中分散均匀性的标准偏差。并且以改性沥青用基质沥青样本在指纹区吸光度的平均标准偏差作为阈值,可以直接对SBS在改性沥青中的分散均匀性进行定量评估。该方法操作简单,测试时间短,测量结果具有较高的精度。目前只对刚刚制备出的改性沥青进行分散均匀性研究,对于不同贮存时间下改性沥青中SBS分散均匀性的检测将在今后的研究工作中开展。
