| 摘 要： | 以丙烯酸（AA）、衣康酸（IA）、2-丙烯酰胺-2-甲基丙磺酸（AMPS）为反应单体，过硫酸钾和亚硫酸氢钠为氧化-还原体系引发剂，通过自由基聚合制备了IA/AA /AMPS三元共聚物水煤浆分散剂，并通过红外光谱（IR）、黏度仪等进行了测试与表征。结果表明，共聚物中成功引入了磺酸基和羧酸基；同时对不同水煤浆浓度和不同分散剂添加量的水煤浆进行了研究；结果表明，水煤浆的最佳成浆浓度为68%，当添加量为0.6%时，分散效果最佳。

| Abstract: | Through the radical polymerization, IA/AA/AMPS terpolymer coal-water slurry (CWS) dispersant was prepared by acrylic acid (AA), itaconic acid (IA), 2-acrylamide-2-methylc sulfonic acid (AMPS), using water as solvent, potassium sulfate and sodium sulfite as the redox initiation system and sodium hypophosphite as chain transfer agent. Also, the slurry properties of the dispersant were investigated through IR, rheometer. The results showed sulfonic group and carboxylic acid group were successfully introduced into copolymer;The results showed that the optimal dispersant effect appeared when concentration of coal-water slurry was 68% and adding amount of was 0.6% of the total amount of monomers. |
