在十二烷基硫酸钠(SDS)/辛基苯基聚氧乙烯醚(OP-10)为复合乳化剂的作用下,采用半连续种子乳液聚合的方式,主要以丙烯酸丁酯(BA)为核层,以丙烯酸丁酯(BA)、甲基丙烯酸甲酯(MMA)、甲基丙烯酸十二氟庚酯(DF-MA)、丙烯酸(AA)、N-亚甲基双丙烯酰胺(MBA)为壳层,合成了具有核-壳结构的P(BA-MMA-DFMA-AA-MBA含氟丙烯酸酯五元共聚物乳液。当AA用量为单体的1%,MBA用量为单体的2%时,便可获得聚合稳定、吸水率较低、拉伸强度增强30%以上的含氟丙烯酸酯树脂。
Under the action of sodium dodecyl sulfate (SDS) / octylphenyl polyoxyethylene ether (OP-10) as the composite emulsifier, the semi-continuous seed emulsion polymerization was adopted, mainly using butyl acrylate (BA) (BA), methyl methacrylate (MMA), dodecafluoroheptyl methacrylate (DF-MA), acrylic acid (AA) and N-methylenebisacrylamide (MBA) As the shell, P (BA-MMA-DFMA-AA-MBA fluorinated acrylate copolymer emulsion with core-shell structure was synthesized. When the amount of AA is 1% of the monomer, the amount of MBA is 2 %, A fluorinated acrylate resin having stable polymerization, low water absorption, and a tensile strength of 30% or more can be obtained.
