| 摘 要： | 以二乙烯三胺、己二酸和环氧氯丙烷为原料,通过缩聚和交联反应合成了具有水溶性的阳离子热固性树脂聚酰胺-环氧氯丙烷树脂(PAE).在酸胺摩尔比1.05:1、加热温度170℃、催化剂用量2.5%、保温时间120 min的条件下,得到出水率高、聚合度大、相对分子质量适宜的预聚体PA;在环氧氯丙烷与预聚体PA中的二乙烯三胺单元摩尔比1.5:1、前期水与PA质量比2:1、保温温度65℃的条件下,制得的PAE与市售PAE相比,稳定性增强,湿强效果明显提高.

| Abstract: | By polycondensation and cross-linking with diethylenetriamine,adipic acid and epichlorohydrin as raw materials,a water-soluble,cationic and thermosetting resins PAE is prepared.①Step 1:with n(AA):n(DETA)=1.05:1,heating temperature of 170℃,catalyst amount of 2.5%,the keeping time of 120 min,the prepared intermediate PA has a low impurity,high water rate and appropriate molecular weight.② Step 2:under the conditions of n(ECH):n(DETA)=1.5:1,m(pre-water):m(PA)=2:1,and the holding temperature of 65℃,the prepared PAE not only has stronger stability,but also has better wet-strength than the other commercial products. |
