煤沥青基高软化点纺丝沥青及其制备方法
摘要：
本发明公开了一种煤沥青基高软化点纺丝沥青及其制备方法。所述的煤沥青基高软化点纺丝沥青软化点为270～285℃，结焦值为80.0～84.0％，可纺性好，连续纺丝可达18000米以上。其制备方法过程包括：在管式氧化炉中，将不含有原生喹啉不溶物的煤焦油沥青，通入空气氧化处理，然后在反应釜中热缩聚处理，制得高软化点纺丝沥青。本发明的优点：制备工艺简单，可控性好，原料来源广泛，产品收率达到60％以上，适合工业化生产。
摘要（英）：

The invention discloses a coal tar pitch-based high-softening point spinning pitch and a preparation method thereof. The softening point of the coal tar pitch-based high-softening point spinning pitch is 270 DEG C to 285 DEG C, the coking value is 80.0 to 84.0 percent, the spinnability is good, and continuous spinning can reach more than 18000 meters. The preparation method for the coal tar pitch-based high-softening point spinning pitch includes the following steps: in a tube type oxidation furnace, the air is filled to oxidate coal tar pitch which does not contain primary quinoline insoluble, thermal polycondensation treatment is then carried out in a reaction kettle, and thereby the high-softening point spinning pitch is prepared. The invention has the advantages that: the preparation process is simple and highly controllable, the source of the material is rich, the product yield reaches more than 60 percent, and the invention is suitable for industrialized production.
