摘要
河南天宏焦化公司以中温煤沥青为原料研制改质沥青,在高压反应釜内先进行净化处理,然后采用加热聚合法进行改质,所得改质沥青喹啉不溶物QI为11%~12%,甲苯不溶物TI为32%~36%,β树脂20%~24%,软化点108~112℃,结焦值59.5%~60%,符合国家一级标准,可用作生产超高功率石墨电极的粘结剂.
With medium-temperature coal asphalt as the feedstock,modified asphalt was produced at Henan Tianhong Coke Chemistry Company by a process of its purification in high-pressure autoclave followed by thermo-polymerization,giving a product containing 11-12% insoluble in quinoline and 32%~36% insoluble in toluene,20%~24% βresin,with a softening temperature of 108~112oC and coking value of 59.5%~60%;as a whole,it was up to the national first grade standard and qualified to be a binder for production of super-high capacity graphite electrode.
