Using diethanolamine as aminating agent and glacial acetic acid as neutralizing agent, aminated epoxy acrylic cationic resin was prepared. the effect of technology of aminated epoxy acrylic resin on properties of eletrodeposition was studied by conductivity meter and electrophoresis apparatus. it was shown that, conductivity firstly decreased, and then increased with aminating temperature increase. in contrast with putting polyacrylic resin into thin acetic acid solution, the more compact film could be achieved by neutralizing polyacylic resin with glacial acetic acid and then add it into water. when neutralizing temperature was enhanced, the speed of electrodepsidon was found to increase, and the film was also more compact. increasing the dn leads to enhanced conductivity and smaller particle size. when dn equaled to 80, the smoothest film could be achieved

    以二乙醇胺為胺化劑、冰醋酸為中和劑，合成了胺化環氧丙烯酸陽離子樹脂.採用電泳儀和電導率儀，研究了胺化環氧丙烯酸樹脂合成工藝對陰極電泳塗料電沉積性的影響.結果表明，隨著胺化溫度的增加，電泳液電導率先下降後上升.將冰醋酸加入樹脂中中和，後用水稀釋，比樹脂在醋酸稀溶液中中和，電沉積性能更好.電沉積速率隨著中和溫度的上升而增加，電沉積膜緻密性相應增加.中和度（ dn ）愈高，電泳液電導率愈大，粒徑越小，而塗膜外觀在中和度為80時達到最佳
