A water-soluble thermosetting acrylate paint for cold-rolled silicon steel is prepared from water-soluble acrylic acid, inorganic solid filler and cross-linking agent through proportionally mixing them together, stirring, adding deionized water for deluting it, homogenizing and sand grinding. Its advantages are high resistance to cold and weather, high adhesion, uniform color, and high antirust performance. 本发明涉及的是一种水溶性热固化丙烯酸脂冷轧硅钢涂料。其结构是各组份所占的重量比：水溶性丙烯酸树脂∶无机固体填料∶交联剂＝59-61∶20-22∶19，其主要制备工艺：首先制备水溶性丙烯酸树脂，在水溶性丙烯酸树脂中加入无机固体填料和交联剂混合搅拌均匀，然后再加入水溶性丙烯酸树脂、无机固体填料以及交联剂总量的30-40％的去离子水，在去离子水释到粘度为15-29秒，用涂-4粘度计测定，温度25℃，最后放入料桶内匀料，砂磨制得。本发明的优点：经实际使用，耐制冷剂R22、R134α，耐候性能-5℃～45℃，发兰试验，无剥离现象，色泽均一，防锈性能好，在水中浸泡72小时不生锈，储藏条件45℃不变质。
