环保型造纸湿强剂的研究进展

The Research on Environmentally Friendly Wet-Strength Agents for Papermaking

文章概述了造纸湿强剂的技术现状和研究进展,着重讨论了传统造纸湿强剂聚酰胺多胺环氧氯丙烷(PAE)以及羧甲基纤维素(CMC)和改性壳聚糖等环保型造纸湿强剂对纸张湿强性能的影响及机理,介绍了聚羧酸、阳离子淀粉、纳米微晶纤维素和海藻酸钠作为造纸湿强剂的应用现状,并分析归纳了它们的优缺点,以期为造纸湿强剂的发展提供一定的理论依据和技术支撑。

Progresses in synthesis technologies and development activities of wet-strength agents for papermaking were reviewed. The paper focused on the effect of the environmentally friendly wet-strength agents, including polyamideamine-epichlorohydrin （PAE）, carboxylmethyl celluloses （CMC） and modified chitosan, on the wet strength property of the paper and the corresponding mechanisms. The application of polycarboxylic acids, cationic starch, nanocrystalline cellulose, and sodium alginate, as well as their advantages and disadvantages were in- troduced. Finally the future research direction of wet-strength agents was discussed.
