摘要: 根据原生QI杂质由微米级炭粒构成的特性,采用溶剂絮凝法对煤焦油进行了净化处理,以净化煤焦油为原料制备了低QI含量的高性能浸渍剂沥青,对比研究了高性能浸渍剂沥青的流变性能和渗透性能。结果证实:高性能浸渍剂沥青极大地改善了浸渍效果,并且使炭/炭复合材料的力学性能显著提高。

Abstract: According to the character of primary QI impurities composed of carbonaceous particles with the size of several micrometers, the coal tar was purified by the solvent flocculation method. Using the purified tar as raw material, high performance impregnating pitch with low QI content was prepared. The rheologic behavior and permeability of high performance impregnating pitch were comparatively studied. It has been confirmed that the high performance impregnating pitch modifies greatly impregnation efficiency. The mechanical characteristics of C/C composite have been evidently improved.
