摘要:本研究分别分析了单元助留体系阳离子聚酰胺环氧氯丙烷树脂（PAE），双元助留体系PAE/阴离子聚丙烯酰胺（APAM）、PAE/膨润土（MMT）、PAE/阳离子聚丙烯酰胺（CPAM），三元助留体系PAE/CPAM/APAM、PAE/CPAM/MMT对装饰原纸TiO₂/滑石粉复合填料留着效果的影响。确定了各个体系的最佳添加量，并筛选出助留效果最好的助留体系。结果表明，当PAE添加量2.0%、CPAM添加量0.08%、MMT添加量0.6%时，组成的PAE/CPAM/MMT三元助留体系留着效果最佳，此时，浆料和填料留着率分别为89.5%和65.0%，纸张的不透明度、白度及匀度分别为98.5%、86.6%和91。

Abstract:In this paper， the retention results of retention systems such as cationic polyamide epichlorohydrin resin （PAE）， PAE/anionic polyacrylamide （APAM）， PAE/bentonite （MMT）， PAE/cationic polyacrylamide （CPAM）， PAE/CPAM/APAM， and PAE/CPAM/MMT on retention rate of titanium dioxide/talc composite filler in preparing decorative base paper were studied， and the optimal dosage of each system was determined. The results showed that when the dosage of PAE， CPAM， and MMT were 2.0%， 0.08%， and 0.6% respectively， ternary retention system of PAE/CPAM/MMT had the best retention results， the retention rates of pulp and filler were 89.5% and 65.0%， respectively， and the opacity， whiteness， and formation of the paper were 98.5%， 86.6%， and 91， respectively.
