丙烯酸改性PAE树脂性能的研究

摘要

用丙烯酸对PAE树脂进行改性，以期替代传统PAE树脂作为纸张的增强剂。探讨了在PAE树脂中引入丙烯酸的改性工艺及其应用，同时对改性PAE树脂的增强性能进行了研究。研究结果表明：在PAE树脂成品中引入9%的丙烯酸为最佳改性工艺，在此工艺条件下制备的改性PAE树脂对纸张的增强效果最佳；当改性PA E树脂用量为0.6%时，与使用1.0%传统PAE树脂的增强作用效果基本相当；另外在PAE树脂成品中引入丙烯酸，有利于PAE树脂成本的降低。研究成果对改性PAE树脂的研究、开发及应用具有较强的参考价值。%PAE resin was modified with acrylic resin, instead of traditional PAE resin as paper strengthening agent. The improvement process and its application for the combination of acrylic with PAE resin were discussed, as well as the performance of the modified PAE resin as paper strengthening agent. The results show that adding amount of 9%acrylic into the PAE resin can reach to the best strengthening effect; when dosage of modified PAE resin is 0.6%, the strengthening effect is equal to the traditional PAE resin at the dosage of 1.0%; in addition, adding acrylic into PAE resin can reduce the cost of the PAE resin. The results will provide as a reference on the research, development and application of modified PAE resin.
