以煤沥青为原料制取高质量筑路油

Taking Coal Pitch as Feedstock to Produce High Quality Road Oil

用添加橡胶、抗氧化剂和溶剂油等方法,优选出了以煤沥青为原料生产高质量橡胶改质筑路油的工艺条件和配方,工业试产表明,改质筑路油不仅质量好,而且生产成本低。

By means of adding rubber, inhibitor and solvent naphtha, the process condition and formula of taking coal pitch as feedstock to produce high quality rubber-improved road oil. The commercial trial-production shows that the improved road oil not only has good quality, but also has lower production cost.
