摘　　要：以生物质基材料替代塑料是当前全球研究的焦点,但是生物质基材料表面含有大量羟基,再加上纤维之间形成的疏松多孔的三维网状结构,使得材料具有一定亲水性,大大限制了其使用范围。本研究以有机硼酸酯表面活性剂作为AKD乳液的乳化剂制备抗水性表面施胶乳液,提高生物质基材料的抗水性。实验结果表明,当乳化剂用量为蜡片质量的6%时,制备的乳液的稳定性及抗水效果最佳,乳液粒径可达到162nm;并且乳液带负电荷,Zeta电位为-52.8mV,可在阳离子型AKD乳液无法使用的场合添加,填补了AKD施胶乳液的空白。Replacing plastics with biomass-based materials is a current global research focus.However,the surface of biomass-based materials contains a large number of hydroxyl groups,and the loose,porous three-dimensional network structure formed between fibers imparts a certain degree of hydrophilicity to the materials,which significantly limits their range of applications.In this study,organic borate ester surfactants were used as emulsifiers for AKD emulsion to prepare water-resistant emulsions,enhancing the water resistance of biomass-based materials.Experimental results indicated that when the emulsifier dosage is 6%of the wax flakes,the stability and water resistance of the prepared emulsion are optimal,with an emulsion particle size reaching 162nm.Furthermore,the emulsion carries a negative charge,with a Zeta potential of-52.8mV,allowing it to be added in situations where cationic AKD emulsions cannot be used,thus filling the gap in AKD sizing emulsions.
