摘要
利用组成分析与热失重分析方法研究了不同添加剂对煤沥青筑路油的改质影响。不同添加剂改质后使沥青中软沥青和甲苯不溶物减少，沥青质增加。沥青质热失重动力学分析说明改质后的沥青质是由添加剂、原沥青质以及其它组分组成的复杂混合物，分子间靠范德华力与氢键力结合在一起。橡胶类添加剂对煤沥青的改质作用显著。
The modification on coal－ tar－ pitch by additives was investigated by composition and thermogravimetry. After modification the content of heptene soluble and toluene insoluble was decreased ,the content of asphaltene was increased. The kinetic analysis of thermogravimetry indicated that asphaltene modified consisted of additives, original asphaltene and others compositions.There were the forces of Van der Walls and hydrogen bonding among asphaltene modecules. The effect modified was remarkable to additiving rubbers.
