将丙烯酸丁酯(BA)、甲基丙烯酸十八烷基酯(SMA)、苯乙烯(St)作为聚合单体,通过悬浮聚合工艺制备了BA-SMA-St油水分离聚合物(PBSS)微球。使用红外光谱仪、显微镜表征了微球的基本结构和形貌,测试了微球的油水分离性能、保油性能以及在不同温度下的吸油性能,并探讨了交联剂用量对微球吸油性能的影响。结果表明:微球具有良好的油水分离性能,随着交联剂用量的增加微球的吸油倍率减小。在25℃下对汽油饱和吸附倍率可达11.72g/g,所需时间为30min;在70℃下对汽油饱和吸附倍率可达12.64g/g,所需时间仅为15min,吸附饱和后微球的保油率高于98%。
Using butyl acrylate(BA),stearyl methacrylate(SMA),and styrene(St) as polymerization monomers,polymer BA-co-SMA-co-St(PBSS) were prepared by a suspension polymerization process,which showed microsphere appearance.Infrared spectrometer and microscope were used to characterize the basic structure and morphology of the microspheres.The oil-water separation performance,oil retention performance and oil absorption performance of the microspheres at different temperatures were tested.In addition,the effect of the amount of crosslinking agent on the oil absorption performance of the microspheres was discussed.The results showed that the microspheres had good oil-water separation performance,and the oil-absorption rate of the microspheres decreased with the increase of the amount of crosslinking agent.The saturated absorption rate of gasoline reached 11.72g/g at 25℃ in 30min.However,the saturated absorption rate of gasoline could reach 12.64g/g at 70℃ in 15minutes.The oil retention rate of the microspheres was higher than 98%.
