| 摘 要： | 研究了表面活性剂对煤沥青浸渍性能的影响.实验结果表明:加入少量的表面活性剂后,煤沥青的软化点、粘度等流变性能都得到较大幅度的改善,而残炭率影响不大.对表面活性剂改性煤沥青的机理进行了比较深入地探讨.

| Abstract: | The effects of the surfactants on the impregnation performance of coal tar pitch are studied in this paper.The results show that the softening point and viscosity of the pitch are significantly decreased by modified with surfactants.These characters are helpful for the impregnation,although the carbon yield decreases slightly.The modifying mechanisms of surfactants on coal tar pitch are also discussed. |

| Keywords: | coal tar pitch surfactant viscosity soft point carbon yield |
