摘　　要：以淀粉、甲基丙烯酸甲酯、丙烯酸丁酯和甲基丙烯酸为主要原料,通过自由基聚合法进行接枝共聚制备了水性丙烯酸酯无氟防油剂,对其化学结构、粒径、Zeta电位和成膜性进行了分析。将水性丙烯酸酯防油剂涂布在原纸上制得食品包装用防油纸,对防油纸的动态油接触角、防油防水性能、耐高温性能、抗冷冻性能和再制浆性能进行了研究。结果表明,合成的水性丙烯酸酯防油剂粒径分布均匀,稳定性良好,平均粒径和Zeta电位分别为254.2 nm和-39.74 mV;防油剂可赋予纸张优良的防油性和防水性,当涂布量为7.5 g/m^(2)时,防油等级可达10.2级,Cobb值从原纸的24.2 g/m^(2)降低至1.9 g/m^(2);且防油纸具有良好的耐高温性能、抗冷冻性能和可再制浆性能。The fluorine-free oil-resistant agent was prepared through free radical polymerization method,with starch,methyl methacrylate,bu‑tyl acrylate and methacrylic acid as raw materials.The chemical structure,particle size,Zeta potential and film-forming properties of the pre‑pared oil-resistant agent were analyzed.Oil-resistant paper for food packaging was prepared by coating waterborne acrylate oil-resistant agent onto base paper,and its dynamic oil contact angle,oil-and water-resistance,high temperature resistance,freezing resistance and repulping performance were studied.The results showed that the synthesized waterborne acrylate oil-resistant agent had uniform particle size distribution and good stability,with average particle size of 254.2 nm and Zeta potential of−39.74 mV.The oil-resistant agent could endow the base paper good oil-and water-resistance.When the coating amount was 7.5 g/m^(2),the oil resistance could reach 10.2 grade,and the Cobb value de‑creased from 24.2 g/m^(2)to 1.9 g/m^(2)compared with the base paper.Furthermore,the oil-resistant paper had good high temperature resistance,freezing resistance,and repulping performance.
