摘　　要：为制备一种环保性好、纸张湿强度提升明显的复合型湿强剂,对传统的纸张湿强剂如脲醛树脂等的性能缺陷进行分析,以2,3-环氧丙基三甲基氯化铵等对聚乙烯亚胺进行改性,制备了一种自交联季铵化聚乙烯亚胺纸张复合型湿强剂,认为这种纸张湿强剂具有环保性强、开发成本低等优势,较一般传统纸张湿强剂而言具有一定优势。In order to prepare a compound wet strength agent with good environmental protection and obvious improvement of wet strength of paper,the performance defects of traditional wet strength agents such as urea-formaldehyde resin were analyzed in this paper,and polyethylenimide was modified with 2,3-epoxy-propyl trimethylammonium chloride,etc.,to prepare a self-crosslinked quaternary ammonium polyethylenimide paper compound wet strength agent.This paper wet strength agent has the advantages of strong environmental protection,low development cost,compared with the traditional paper wet strength agent has certain advantages.
