POE改性沥青性能研究

Study on the Properties of POE Modified Asphalt

如今SBS(苯乙烯-丁二烯-苯乙烯三嵌段共聚物)改性沥青的主要不足是SBS裂解老化。主要原因是SBS分子结构中存在不饱和键。笔者选择聚烯烃弹性体(POE),以改善SBS的抗老化性能。

bThe main deficiency of SBS（styrene-butadiene-styrene tri-block copolymer） modified asphalt now is cracking and aging of SBS.The main reason is that there are unsaturated bonds in the molecular structure of SBS. Polyolefin elastomer（POE） was selected to improve the anti-aging properties of SBS.
