| 摘 要： | 针对扬声器纸盆、纸浆餐盒等抗水性要求高的模塑产品,研究了在阳离子聚酰胺-环氧氯丙烷树脂(PAE)和羧甲基纤维素(CMC)组成的PAE/CMC二元增强体系中苯丙乳液浆内施胶效果.结果表明,在PAE/CMC二元增强体系中,PAE与CMC的电荷比影响苯丙乳液施胶效果,当PAE与CMC的电荷比在1.5 ～4.0之间,随着PAE和CMC的电荷比的增加,纸张施胶度快速增加,继续增加PAE与CMC的电荷比,纸张施腔度变化趋缓,当PAE与CMC的电荷比为8.0时,继续增加PAE与CMC的电荷比,纸张的施胶度基本不变.

| Abstract: | In this paper,the efficiency of styrene-acrylic emulsion as internal size was discussed when both cationic polyelectrolyte polyamideamine epichlorohydrine(PAE) and anionic poly-electrolyte carboxymethyl cellulose(CMC) were added as strength additives in the papermaking process.The added amount of styrene-acrylic emulsion had a remarkable effect on internal sizing and paper strength.When the dosages of PAE and CMC were constant,and breaking length increased while tear index decreased.Raised amount of PAE cou... |
