以腐植酸为起始原料，采用先磺化、再与甲醛及磺化丙酮进行缩聚反应，合成了一种新型缩合型腐植酸水煤浆分散剂．通过红外光谱（IR）、热重（TGA）对其结构进行了表征，对分散剂应用于彬长煤制备水煤浆的性能进行了研究，并考察了目标产物水溶液对煤粒表面的动态接触角、与煤粒复合体系的Zeta电位、水煤浆的流变性能和稳定性等的影响．结果表明，该腐植酸水煤浆分散剂用量为0．3％（对干基煤质量），且获得的水煤浆浓度为67％时，其表观黏度为930 m Pa · s左右，且水煤浆的流变性和稳定性等性能较理想．

A novel humic acid based dispersant has been got from humic acid as basic raw ma-terials by sulfonation and condensation polymerization reaction .The copolymer was charac-terized and analyzed by infrared spectrum (IR) ,TGA .The contact angle of solution of dis-persant on coal particle surface and the Zeta potential of complex of dispersant and coal parti-cle has been made .The effects of the dosage of dispersant on apparent viscosity ,rheological behavior and static stability of coal water slurry have been investigated .The result have been showed when the dosage of dispersant is 0 .3% (based dry coal )the apparent viscosity of coal water slurry would be 930 mPa · s with the concentration of CWS was 67% .The perform-ance of rheological behavior and static stability of coal water slurry was meet demand .
