【摘要】：以衣康酸(IA)、苯乙烯磺酸钠(SSS)、2,2-二羟甲基丙酸(DMPA)为单体,过硫酸铵为引发剂,采用水溶液自由基聚合法,合成了一种含有羧酸基、磺酸基和羟基的多元衣康酸共聚阻垢剂。研究了反应物单体配比、反应温度、反应时间、引发剂质量分数对共聚物阻垢剂阻垢性能的影响。结果表明,在IA∶SSS∶DMPA(摩尔比)=4∶1∶1.5,引发剂用量占单体质量分数的11%,反应温度为90℃,反应时间为2.5 h条件下制得的共聚物阻垢剂阻垢性能最佳。通过静态阻垢法进行了阻垢剂的阻垢性能的评定,当此三元共聚物阻垢剂加剂量为12 mg/L时,对CaCO_3的阻垢率可达94.9%,用红外光谱和扫描电镜对共聚物阻垢剂的结构和CaCO_3垢样进行了表征。其中扫描电镜表明,加入此衣康酸三元共聚阻垢剂后,CaCO_3呈现明显的疏松结构。
[Abstract]:A polyitaconic acid copolymerization inhibitor containing carboxylic acid, sulfonic acid and hydroxyl groups was synthesized by free radical polymerization of itaconic acid (IA), sodium styrene sulfonate, (SSS), 2, dimethylol propionic acid (DMPA), ammonium persulfate as initiator, and ammonium persulfate as initiator. The effects of monomer ratio, reaction temperature, reaction time and mass fraction of initiator on the scale inhibition of copolymer scale inhibitor were studied. The results show that when the molar ratio of IA:SSS:DMPA is 4: 1: 1.5, the mass fraction of initiator to monomer is 11%, the reaction temperature is 90 鈩，
