中文摘要:
      目的 确定含氟丙烯酸酯共聚物乳液的最佳配方, 研究其涂膜表面的疏水疏油性、 热力学稳定性等性能。方法 以甲基丙烯酸甲酯(MMA)、 丙烯酸丁酯(BA)、 丙烯酸(AA)为原料, 丙烯酸十三氟辛酯(PFOA)为含氟单体, 过硫酸铵(APS)为引发剂, 烷基酚聚氧乙烯醚(OP-10)和十二烷基磺酸钠(SDS)为复合乳化剂, 去离子水为分散介质, 采用半连续种子乳液聚合法制备核壳型含氟丙烯酸酯共聚物乳液。通过CA, FTIR, DSC, TG和AFM等仪器, 对共聚物涂膜的疏水疏油性能、 热力学性能及表面化学成分进行表征。结果 当乳化剂(OP-10与SDS的质量比为2∶1)的质量分数为3%、 引发剂(APS)的质量分数为0.6%、 丙烯酸十三氟辛酯(PFOA)的质量分数为9%时, 单体转化率最高、 凝胶率最低, 涂膜对水和十六烷的接触角分别为114°和85°。结论 合成的乳液具有良好的疏水疏油性和热力学稳定性等性能, 适合油墨罐内壁涂料等产品。
英文摘要:
      Objective To identify the best formula of fluorinated acrylate copolymer emulsion, and investigate the performance parameters such as hydro-oleophobic and thermodynamic properties. Methods A series of fluorinated acrylate copolymer latex with core–shell structure were synthesized by semi-continuous seeded emulsion polymerization method using methyl methacrylate(MMA) , butyl acrylate(BA)and acrylic acid(AA)as the raw material, PFOA as the fluorinated acrylate monomer, ammonium persulfate (APS) as the initiator, sodium dodecyl sulfate (SDS) and polyoxyethylene octyl phenyl ether(OP-10)as the complex emulsifier and taking water as the dispersion medium. The hydro-oleophobic and thermodynamic properties as well as the surface chemical components were characterized by contact angle goniometer(CA) , fourier transform infrared (FTIR) spectroscopy, differential scanning calorimetry (DSC) , thermogravimetry analysis(TG)and atomic force microscopy(AFM) , respectively. Results The results showed that when the dosage of emulsifier was 3%, the initiator content was 0.6%, and the mass fraction of fluorinated monomer was 9%, the monomer conversion was the highest and the gel rate was the lowest, while the water contact angle and hexadecane contact angle reached 104° and 71° , respectively. Conclusion The emulsion shows good performance including hydro-oleophobic and thermodynamic properties, and is therefore suitable as inner wall coating of the ink tank and other products.
