摘　　要： 探讨了羧基改性剂对PAE树脂的改性方式、改性剂用量,并对改性PAE树脂进行表征,研究了改性PAE树脂的应用效果.结果表明羧基改性剂可以对PAE树脂进行改性,且改性后提高了PAE树脂的增干强效果.实验结果显示:羧基改性剂对PAE树脂的末端改性优于过程改性;末端改性时,羧基改性剂的较佳引入量为9%;当末端改性后的PAE树脂用量为0.5%时,与改性前相比,能够使纸张干抗张指数提高约11%,湿抗张指数降低约8%,耐折度提高约17%,撕裂指数提高约27%,内结合强度提高约47%.另外,在PAE树脂成品中引入羧基改性剂改性,有利于PAE树脂成本的降低,也有利于损纸的回收. This paper researched on the modified method of PAE resin with carboxyl modifi- er, discussed the dosage of modifier, characterized modified PAE resin and studied the appli- cation of the modified PAE resin. The results showed that carboxyl modifier can undertake modification of PAE resin, and also improve the effect of the dry strength of PAE resin. Ex- perimental results show that add carboxyl modifier into the PAE resin product is the best process. Modified PAE resin has high dry strength performance and low strong wet strength performance. The better dosage of carboxyl modifier is 9%. When modified PAE resin dosage was 0.5%, compared with traditional PAE resin can improve the paper dry tensile index a- bout 11 %, and reduce about 8$ wet tensile index, folding resistance degree increases by a- bout 17%, tearing index increases by about 27%, the bond strength increases by about 47%. The results of this research had a strong reference value on the modified PAE resin study, exploitation and application.
