摘　　要：采用半连续乳液聚合法,以甲基丙烯酸甲酯(MMA)和丙烯酸丁酯(BA)为聚合单体,丙烯酸(AA)为功能单体,2-丙烯酰胺-2-甲基丙磺酸(AMPS)为改性剂,N,N-亚甲基双丙烯酰胺(DMAA)为交联剂,过硫酸铵(APS)为引发剂,十二烷基硫酸钠(SDS)和烷基酚聚氧乙烯醚(OP-10)为乳化剂,合成一种具有改善辽河油田稠油脱水效果的纯丙乳液破乳剂。研究乳化剂、引发剂对破乳剂脱水性能的影响以及交联剂对破乳剂性能的影响,并运用红外光谱、凝胶渗透色谱、激光粒度分析仪和紫外分光光度计进行表征分析。通过实验确定合成破乳剂的最佳工艺条件:乳化剂质量分数(占单体总质量)为10%,引发剂质量分数为0.8%,交联剂质量分数为0.8%,在此条件下脱出污水含油率为47.50 mg/L,达到出矿污水的排放标准。Using semi-continuous emulsion polymerization,methyl methacrylate(MMA),butyl acrylate(BA)as the polymerization monomer,acrylic acid(AA)as the functional monomer,2-acrylamide-2-methyl⁃propanesulfonic acid(AMPS)as modifier,ammonium persulfate(APS)as initiator,sodium dodecyl sulfate(SDS)and alkylphenol ethoxylate(OP-10)as emulsifier,which synthesized an improved Liaohe oilfield heavy pure acrylic emulsion demulsifier for dehydration effect.The effects of emulsifier mass fraction,icross⁃linker mass fraction were studied,and characterized by infrared spectroscopy,gel permeation chromatogra⁃phy,laser particle size analyzer and UV spectrophotometer.The optimal synthesis conditions were obtained by experiment.When the mass fraction of emulsifier(accounting for total monomer mass)was 10%,mass frac⁃tion of initiator was 0.8%,and the mass fraction of the modifier was 0.8%,the oil content of the dewatered sewage was only 47.5 mg/L,which met the requirment of discharge standards for mine sewage.
