摘要
采用不含磷氮的药剂衣康酸(IA)和甲基丙烯磺酸钠(SMAS)合成了环保型的两元共聚物药剂,并系统研究了合成工艺条件对共聚物性能的影响.最终得到最佳合成条件如下:原料质量比(IA∶SMAS)为 2∶1,聚合温度为95℃,聚合时间为6h;此外,引发剂和链转移剂的添加量均为原料总质量的5%.经静态阻垢实验研究表明,合成的共聚物具有优异的阻垢性能和分散性能.将该共聚物与静电场结合用于阻垢性能研究,结果表明静电场的存在使IA/SMAS的阻垢性能提高了17%,静电与IA/SMAS共聚物具有协同增效作用.
Abstract
An environmentally friendly binary copolymer agent was synthesized using the phosphorus-and nitrogen-free agents itaconic acid(IA)and sodium methacrylate sulfonate(SMAS)monomers,and the effects of the synthesis process conditions on the copolymer properties were systematically investigated.The optimal synthesis conditions were as follows:the mass ratio of raw materials(IA∶SMAS)was 2∶1,the polymerization temperature was 95℃,and the polymerization time was 6 h.In addition,the additions of initiator and chain transfer agent were 5%of the total mass of raw materials.The static scale inhibition ex-perimental studies showed that the synthesized copolymer has excellent scale inhibition and dispersion properties.The copolymer was combined with an electrostatic field for scale inhibition studies,and the re-sults showed that the presence of electrostatic field increased the scale inhibition performance of IA/SMAS copolymer by 17%,and that the electrostatic force had a synergistic effect with IA/SMAS copolymer.
