Abstract

Abstract Sustainable coatings exhibit potential in enhancing oil resistance of packaging paper. Alkyl ketone dimer (AKD) was used to esterify sodium alginate (SA) to prepare water and oil resistant agent SAD. As SAD was coated on paper, it reduced the surface energy and blocked the fiber pores of paper, thus improving the barrier performance of paper. The oil resistance grade can reach grade 6 at coating amount of 2.13 ± 0.26 g/m 2 , which is qualified for food packaging. The coated paper also showed good barrier to hot castor oil. Resistance to organic solvent and water were also enhanced with initial water contact angle (WCA) increased to 69.2°. Compared with base paper, SAD coated paper had better mechanical properties and more importantly, coated paper can be effectively recycled to achieve green recycling.

烷基烯二聚体改性海藻酸钠增强耐水性的可回收耐油纸

摘要可持续涂料在提高包装纸耐油性方面表现出潜力。采用烷基酮二聚体(AKD)对海藻酸钠(SA)进行酯化制备耐水耐油剂SAD。由于将SAD涂在纸上，降低了纸的表面能，堵塞了纸的纤维孔隙，从而提高了纸的阻隔性能。在涂覆量为2.13±0.26 g/ m2时，耐油等级可达6级，可用于食品包装。涂布纸对蓖麻油也有良好的阻隔性。初始水接触角(WCA)达到69.2°，提高了材料对有机溶剂和水的抗性。与原纸相比，SAD铜版纸具有更好的机械性能，更重要的是铜版纸可以有效地回收利用，实现绿色回收。
