摘　　要：讨论了升温时间和加水量等主要因素对聚酰胺多胺环氧氯丙烷树脂(PAE)中间体合成的影响,并找到比较合适的条件。在此条件下,通过正交实验,综合分析温度、时间和改性剂M加入量在合成过程中的作用,最终确定低成本改性PAE的最佳合成条件为:改性剂M的加入量为40%,温度50℃,时间90min,并再进行环氧化反应。在抄纸应用实验中,通过测量纸的增干、湿强性能,表明了低成本改性PAE使用效果良好。This paper discussed the impact of factors such as the time of temperature rising, the amount of water added, on the synthesis of PAE intermediate, and found suitable synthesis conditions for the intermediate. Under these conditions, the effects of temperature, time and the added amount of modifier M on the synthesis process were comprehensively analyzed by orthogonal experiments. The synthesis process of cost-effectively modified PAE is established as ： the addition level of modifier M is 40% ; the temperature is 50 ℃ ; the time is 90 min before epoxy reaction. The obtained low cost modified PAE shows good performance on dry strength and wet strength enhancement.
