化学反应改性石油沥青及其应用探索

The Study on Chemical Modified Asphalt and Its Application

对掺入各种不饱和单体进行沥青加成反应所得的化合物和用化学试剂处理所得的化学反应产物的主要性能进行了比较 ;探讨了上述化学反应的沥青与各种不同聚合物共混后的性能。认为用化学方法来改性石油沥青 ,能使沥青的主要性能发生变化 ,呈现较好的感温性能 ,且经改性后的沥青与聚合物的相容性提高。

The main performances of asphalt′s addition compound prepared by blending various unsaturated monomer were compared to the same ones of asphalt′s chemical reaction products which made by adding chemical reagents .The property of the compounds blended by the modified asphalt illustrated above with the different polymer were discussed .It was considered that asphalt′s main properties can be changed by using chemical methods to modify asphalt .The modified asphalt has better property of temperature sensitivity .And the compatibility of such modified asphalt with the polymer may be improved.
