摘    要：利用异氰酸酯对丙烯酸树酯电泳涂料进行改性，合成了一种耐性较好的新型水溶性电泳涂料．经表征及测试漆膜的性能证实，改性后的涂料，在0．1Mol／NaOH溶液中，漆膜的耐碱稳定时间由2h增至36h，耐25%(质量分数)盐水性能由3H增加至72h以上；树脂失重30%的耐热温度由交联前的120℃增加至340℃，泳透力大于15cm.

Abstract: Acylic electrophoretic coating was modified with isocyanate,and then a new anti corrosion electrophoretic coating was prepared.The results characterized by IR,TG,SEM tests indicated that the corrosion resistance of the coating was improved:while it was soaked in 0 1 mol/L NaOH solution,the time for no fall and no spongy is prolonged from 2 hours to 36 hours;in 25% NaCl solution,the time is 72 hours instead of 3 hours.Meanwhile,the heat resistance temperature for 30% weight loss of the ester rises from 120 to 340 ℃.
