Description

一种新型高效环保钝化剂
技术领域
本发明涉及钝化剂的技术领域，具体地说是一种新型高效环保钝化剂。
背景技术
钢铁材料的腐蚀无时无刻不在发生，为了提高钢铁零件的耐腐蚀性，钢铁材料表面喷涂是一种常见工艺，通常在钢铁零件表面电镀锌或热镀锌。喷涂前为提高涂料与金属基体的附着力、防止表面腐蚀，就必须采取磷化、钝化处理方法。目前，公知的钝化剂是以铬(Cr)酸盐为代表的重金属盐为主，该类物质由于很难自然降解，对环境有很大的破坏。同时钕铁硼磁性材料、金属粉末冶金件、铸件等是一种疏松、多空的基体工件，由于其特殊的物理化学性质，目前的钝化剂对此类材料的工件都有一定的腐蚀作用。
发明内容
为了克服上述缺陷，本发明提供了一种新型高效环保钝化剂。
本发明解决其技术问题所采用的技术方案是：一种新型高效环保钝化剂，包括由下料材料按以下重量百分比组成：醋酸钠5-10％，碳酸氢钠8-15％，钼酸盐8-10％，高效封闭剂5-10％，PH调节剂0.5-1％，余量为水；高效封闭剂来对形成的钝化层表面进行封闭及平整处理，使处理后的钝化膜更加平整、颜色更加均匀、耐蚀性能更加优秀。
在本发明的一个较佳实施例中，醋酸钠5-8％，碳酸氢钠8-12％，钼酸盐8-10％，高效封闭剂5-8％，PH调节剂0.5-1％，余量为水。
在本发明的一个较佳实施例中，pH调节剂为硝酸。
在本发明的一个较佳实施例中，高效封闭剂为氟锆酸、氟硅酸与氧化铬纳米颗粒的复配物。
本发明的有益效果是：本发明能够在镀锌钢件表面得到稳定的钝化膜，该钝化膜结构致密，具有亲水性，上涂涂装附着性良好，不变色，具有优异耐蚀性；本发明可以自然降解，降解的产物为钼氧化物和水等简单的物质，对环境无不利影响且对工件无腐蚀作用，便于大范围推广使用。
