摘要
本文阐明了分子量分布对沥青性能的影响,通过红外谱图讨论了催化氧化沥青与普通氧化沥青的组成结构差异,从理论上分析了分别以磷酸和三氯化铁为代表的两大类催化剂的沥青催化氧化反应历程.解释了沥青普通氯化过程和催化氧化过程的诱导期问题.
The paper shows the influence of molecular weight distribution on the proper- ties of asphalts and discusses the composltlonal difference between catalytic and common oxidized asphalts through the ultra—red spectrum.It also analyses theoretically the asphalt catalytic oxi- dization processes employing phosphoric acid and iron trichioride as catalysts respectively.The induction periods during common and calalytic oxidization processes are explained.
