摘　　要：以腐植酸为基本原料,经过磺化,再以丙烯酸为单体,过硫酸钾为引发剂,采用溶液聚合法,制备磺化腐植酸-丙烯酸接枝共聚物,并检测其对水煤浆的黏度、流变性和稳定性的影响.还研究了不同分散剂用量对水煤浆成浆性能的影响,结果表明,分散剂有效成分为水煤浆总重量的0.12%时,水煤浆具有最低的表观黏度.To humic acid potassium as basic raw materials, through sulfonation ,was pu- rified humic acid, and then as raw materials, acrylic acid as monomers of copolymerization, po- tassium persulfate as redox system initiator, the grafted copolymers of sulfonated humic acid and acrylic acid are synthesized by means of aqueous solution of copolymerization. And detect their effect on viscosity, rheology, and stability of coal water slurry. This paper also studies different dispersant dosage on the property of coal water slurry, dispersing agent for coal water slurry of effective components of O. 12% of the total weight, coal water slurry has minimum apparent viscosity.
