摘要:

以乙烯焦油沥青(ETP)为原料,对其进行热聚合改性处理,探讨了聚合反应温度、聚合反应时间、催化剂及交联剂质量分数对改性乙烯焦油沥青(METP)的组成、性质及收率的影响,并结合元素分析、FT?IR、XRD、Raman、热重分析对ETP及METP进行研究,得到了最佳反应条件:聚合反应温度为370 ℃,聚合反应时间为6 h,催化剂和交联剂质量分数为1.50%。在此条件下得到的METP的软化点(SP)为182 ℃,结焦值(CV)为57.66%,β树脂质量分数为42.26%,喹啉不溶物(QI)质量分数为0.87%,符合高碳材料前驱体的要求;METP收率为73.26%。

Abstract:

The effects of polymerization reaction temperature, polymerization reaction time, catalyst and crosslinker addition on the properties of modified ethylene tar pitch (METP) were investigated, and the optimal reaction conditions were obtained by combining elemental analysis, FT?IR, XRD, Raman and thermogravimetric analysis on ETP and METP: The polymerization reaction temperature was 370 ℃, and the polymerization reaction time was 6 h, besides the addition of catalyst and crosslinker was 1.50%. The softening point (SP) of METP obtained under these conditions was 182 ℃, the coking value (CV) was 57.66%, the β resin was 42.26%, and the quinoline insoluble matter (QI) was 0.87%, which met the requirements of high carbon material precursors; The yieid of METP was 73.26%.
