电解板喷涂涂装前常温脱脂皮膜化成处理剂及制备方法
技术领域
本发明涉及一种金属皮膜化成综合处理剂，尤其一种电解板喷涂涂装前常温脱脂皮膜化成处理剂及制备方法。
背景技术
金属构件表面因油垢、浮锈、重锈、氧化皮及焊接高温氧化物等，因此以往在喷涂涂装等工艺处理前，都是将上述油锈皮等清除掉且大多通过磷酸盐转化处理，使其表面生成一层具有一定粗糙度、多孔性、吸附性的黑色、银灰色或彩色磷酸盐转化膜（皮膜），以增强工件表面耐腐性、提高工件表面与涂层间或其他有机表面处理层间的附着力。如目前对于电解板喷涂涂装前处理工艺流程为：加温60℃喷淋四合一磷化→加温60℃喷淋四合一磷化→喷淋水洗→喷淋水洗→烘干→静电粉末喷涂涂装。现有工艺不仅需要加温处理，浪费能源，而且磷化处理剂中含有重金属和磷酸盐等，废水处理复杂且成本大，不利于环境保护。
发明内容
本发明是为了解决现有技术所存在的上述技术问题，提供一种电解板喷涂涂装前常温脱脂皮膜化成处理剂及制备方法。

一种上述电解板喷涂涂装前常温脱脂皮膜化成处理剂的制备方法，其特征在于按照如下步骤进行：先将计算称量的自来水加入到不锈钢反应釜中，启动搅拌器，控制转速60~80转/分钟，然后依次将计算称量的氟锆酸钾、碳酸氢钠、葡萄糖酸钠、焦磷酸钠、三聚磷酸钠、柠檬酸钠、亚硝酸钠、氟化氢铵、MS-575消泡剂徐徐加入到反应釜中，边加入边搅拌，使其充分溶解为透明状液体；再依次将计算称量的硅烷偶联剂、尼纳尔、AEO-9、QYL-290除积碳表面活性剂徐徐加入到反应釜中，搅拌至呈米黄色均匀液体。
