摘　　要：一般的聚丙烯酰胺（PAM）干增强剂在纸张增强的同时具有提高滤水和保留的作用，已经获得了广泛的使用；但是，由于白板纸或者白板纸的生产采用了中性抄造．且大量使用漂白机械热磨浆（BCTMP）等化学机械浆浆料。又使用了碳酸钙等填料降低成本，普通PAM干增强剂效果下降，且会出现滤水和保留下降的抄造性问题。基于此，该文提出了一种全新的PAM干增强剂。该干增强剂具有高架桥度、高相对分子质量和新型结构，与普通PAM相比，在白板纸中性抄造中，增强、助滤、助留效果优异，能够满足白板纸和白板纸的特殊抄造条件。Dry strength agent is known as multifunctional chemicals to enhance paper strength, drainage and retention. PAM has gained widespread use. However, the performance of conventional PAM dry strength agent has become unsatisfactory due to the production of whiteboard paper uses the semi-chemical mechanical pulp such as BCTMP, and uses the filler to reduce costs, such as calcium carbonate, and the resulting neutral papermaking. In this article, a novel PAM dry strength agent with highly-crosslinking structure, higher molecular weight and novel component, was investigated to enhance the strength, drainage and retention of whiteboard papermaking
