摘　　要：本研究以二乙烯三胺、己二酸、环氧氯丙烷为原料合成了高固含量、存贮稳定性较佳的PAE湿强树脂,并研究了PAE湿强树脂的增干、湿强效果以及对AKD施胶的促进作用。结果表明:以二乙烯三胺与己二酸摩尔比为2∶1时,中间体PPC树脂与环氧氯丙烷物质的量之比为1∶0.75时,PAE增湿、干强效果最佳。当PAE树脂加入到AKD乳液中的量为4∶3时,就能起到很好的AKD施胶促进效果,可以使纸张的Cobb值降到28g/m2左右。The high solid content and stability PAE resin was synthesized by using the diethylenetriamine, adipic acid and epichlorohydrina as raw materials. The effects of PAE resin application on dry strength, wet strength and sizing promoting effect for AKD were discussed. The results show that when the ratio of diethylenetriamine to adipic acid was 2：1 ,the ratio of PPC to epichlorohydrin was 1： 0. 75 ,wet strength and dry strength reached a best level. When the ratio of PAE to AKD emulsion was 4：3 ,a good AKD sizing promoting effect could be achieved. The Cobb value dropped to about 28g/m2.
