石油基浸渍沥青的制备综述

A REVIEW OF THE PREPARATION OF IMPREGNATING PITCH FROM PETROLEUM BASE FEEDSTOCK

综述了国内外浸渍剂沥青制备技术的研究现状与发展方向,主要介绍了以润滑油芳烃抽出油为原料制备浸渍剂沥青的技术。根据产品质量要求,需要对原料作相应的改性,介绍了对原料进行改性的工艺,认为石油基原料经过改性后制备浸渍剂沥青符合环保和经济性要求。

The research and development of impregnating pitch home and abroad are reviewed, focusing on the technologies for producing impregnating pitch by taking the aromatic extract from lube base oil as raw material. According to the quality requirements of impregnating pitch, modification of feedstock is necessity. Thus, processes for feedstock modification are introduced as well. It can be seen that the production of impregnating pitch from petroleum base feedstock is feasible and it is an environmental friendly and economic approach.
