高产碳沥青的制备和性能研究

PREPARATION AND PROPERTY OF HIGH CARBON YIELD PITCH

研究了硫化沥青的组成和结构与其产碳率、流变性能和热稳定性能的关系． 结果表明， 硫化法调制煤沥青在软化点１７０℃～２００℃范围内， 产碳率高， 热稳定性好， 是较理想的浸渍剂．

By researching the reaction properties, relation between the consist, structure of sulfuretted pitch and its carbon yield,rheologic property at high temperature, thermal stability, a method of preparing high carbon yield pitch and its impregnating properties were studied. The results showed that the pitch prepared by sulphuration, when its softening point is in the range of 170℃ to 200℃, have high carbon yield (>65%), and good rheologic property and good thermal stability.\;
