摘　　要：本文对AKD在液体包装原纸中的应用进行了初步探究,结果表明:加入AKD会明显降低纸张的边渗透,但对浆料的滤水和成纸的内结合强度有负面影响。浆料的pH为7.0,碱度为200 mg/L时,AKD的施胶效果最好。湿强剂和AKD配合使用有利于成纸的施胶效果,还会提高成纸的强度指标。加入硅溶胶可以提高AKD留着率,有利于AKD施胶。This article explores the application of AKD in liquid packaging base paper,and the results show that the addition of AKD significantly reduces the edge penetration of the paper,but has a negative impact on drainability of pulp and the internal bonding strength of the paper.When the pH of the pulp is 7.0 and the alkalinity is 200 mg/L,the sizing effect of AKD is the best.The combination of wet strength agent and AKD is beneficial for the sizing effect of paper and can also improve the strength of paper.The addition of ludox can improve the retention rate of AKD,which is beneficial for the sizing of AKD.
