摘要
疏水改性聚丙烯酰胺(HMPAM)作为疏水缔合水溶性聚合物重要的分支,具有增黏性、抗盐性和抗剪切性等特性,为研发低成本的HMPAM,以解决工业废水高效处理的问题,通过分析共溶剂法、胶束共聚法、乳液聚合法、自由基界面聚合法、超声波聚合发和超临界CO_2聚合法等HMPAM合成方法,明确了现阶段各种合成方法存在研发生产周期长、成本高、合成效率低和处理效果差等问题,提出将计算机模拟技术和试验结果相结合,完善合成单体和合成方法的搭配系统,寻求更科学、快速和低成本的HMPAM合成方法。
In order to develop the low cost hydrophobically modified polyacrylamide(HMPAM) and to solve the problem of efficient treatment of industrial wastewater,the synthesis of hydrophobically modified polyacrylamides was discussed in this paper.HMPAM,as an important branch of hydrophobic associating water-soluble polymers,has the characteristics of viscosity enhancement,salt resistance and shear resistance.HMPAM synthesis methods such as co-solvent method,micellar copolymerization method,emulsion polymerization method,free radical interfacial polymerization method,ultrasonic polymerization method and supercritical CO 2 polymerization method were also analyzed.Clearly,various synthesis methods have long R & D production cycle and high cost.Besides,the synthesis efficiency is low and the treatment effect is poor.By combining computational simulation technology with experimental results,a more scientific,rapid and low-cost HMPAM synthesis method is proposed by perfecting the system of synthesis monomer and synthesis method.
