Waterborne fluoropolymer emulsions were synthesized using the one-step semi-continuous seed emulsion polymerization of chlorotrifluoroethylene (CTFE), vinyl acetate (VAc), -butyl acrylate (BA), Veova 10, and acrylic acid (AA). The main physical parameters of the polymer emulsions were tested and analyzed. Characteristics of the polymer films such as thermal stability, glass transition temperature, film-forming properties, and IR spectrum were studied. Meanwhile, the weatherability of fluoride coatings formulated by the waterborne fluoropolymer and other coatings were evaluated by the quick ultraviolet (QUV) accelerated weathering test, and the results showed that the fluoropolymer with more than 12% fluoride content possessed outstanding weather resistance. Moreover, scale-up and industrial-scale experiments of waterborne fluoropolymer emulsions were also performed and investigated.
采用三氟氯乙烯(CTFE)、醋酸乙烯酯(VAc)、丙烯酸丁酯(BA)、Veova 10和丙烯酸(AA)的一步半连续种子乳液聚合方法合成了水性含氟聚合物乳液。对聚合物乳液的主要物理参数进行了测试和分析。研究了聚合物薄膜的热稳定性、玻璃化转变温度、成膜性能和红外光谱等特性。同时,通过快速紫外(QUV)加速老化试验对由水性含氟聚合物配制的氟化物涂层和其他涂层的耐候性进行了评估,结果表明氟含量超过12%的含氟聚合物具有优异的耐候性。此外,还进行并研究了水性含氟聚合物乳液的放大和工业规模实验。
