摘　　要：用不同配比的二乙烯三胺对松香进行改性,在湿强剂PAE的作用下形成稳定存在的阳离子松香胶乳液。结果显示,当松香与二乙烯三胺摩尔比为4∶1、改性松香与PAE质量比为1∶1时制得的阳离子松香胶乳液稳定性最佳。当制备的松香胶以淀粉质量4%的比例用于表面施胶时,可达到纸张抗水性指标要求。此阳离子松香胶乳液的生产无需采用昂贵的高温高压均质机,产品稳定性良好,并且具有较好的抗水效果。用其作为表面施胶剂替代传统的阳离子松香胶浆内施胶,施胶剂用量大大降低,废水处理量大大减少,从而大幅降低纸张生产成本。Cationic rosin emulsion can be prepared after the rosin was modified by different proportions of diethylenetriamine under the action of wet strength agent PAE. The results show that when the molar ratio of rosin to diethylenetriamine is 4:1,and the mass ratio of modified rosin to PAE is 1:1,the cationic rosin emulsion has the best stability. When the prepared rosin adhesive is used for surface sizing with the proportion of starch mass 4%,it can meet the requirement of water resistance index of paper. The production of cationic rosin emulsion does not require expensive high temperature and high pressure homogenizer,and the product enjoys good stability and water resistance. Using it as a surface sizing agent rather than the traditional cationic rosin sizing,both the dosage of sizing agent and the amount of wastewater treatment can be greatly reduced,thus significantly reducing the production cost of the paper sheet [1].
