| 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/m2时，防油等级可达10.2级，Cobb值从原纸的24.2 g/m2降低至1.9 g/m2；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。 |
| Abstract:The fluorine-free oil-resistant agent was prepared through free radical polymerization method， with starch， methyl methacrylate， butyl acrylate and methacrylic acid as raw materials. The chemical structure， particle size， Zeta potential and film-forming properties of the prepared 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/m2， the oil resistance could reach 10.2 grade， and the Cobb value decreased from 24.2 g/m2 to 1.9 g/m2 compared with the base paper. Furthermore， the oil-resistant paper had good high temperature resistance， freezing resistance， and repulping performance. |
