| 摘 要： | 以环氧琥珀酸钠(ESAS)、丙烯酰胺(AM)、烯丙基磺酸钠(SAS)为单体,过硫酸铵为引发剂,合成了三元共聚物EAS防垢剂。通过红外光谱图对其结构表征,结果表明合成的产物为目标产物。通过正交实验研究其最佳合成条件为:共聚温度为90℃,共聚时间为3.5h,m(引发剂)∶m(总单体)=12.5%,单体配比n(ESAS)∶n(AM)∶n(SAS)=1.2∶0.6∶1;合成产物对碳酸钙垢具有较好的防垢性能,防垢率达到88.07%。

| Abstract: | A terpolymer scale inhibitor was prepared from epoxy succinic acid sodium（ESAS）,acrylamide（AM） and sodium allyl sulfonate（SAS）,and the polymerization was initiated by persulfate ammonium.Its structure was characterized by infrared spectroscopy,and the results showed that the synthetic product is the target product.Through an orthogonal test were obtained the best synthetic conditions as follows：the reaction temperature is 90 ℃,the reaction time is 3.5 h,the mass ratio of persulfate ammonium to total monomer is 12.5%,and the monomer＇s mole ratio of n（ESAS）∶n（AM）∶n（AS） is 1.2∶0.6∶1.The synthetic product to calcium carbonate scale has a better inhibition performance,and the inhibition rate can amount to 88.07%. |
