Zusammenfassung:The invention relates to a water-based 7-series aluminum alloy soaking corrosion inhibitor and a preparation method thereof, in particular to a water-based soaking corrosion inhibitor used in the surface treatment processes of CNC, polishing or anodic oxidation and the like of 7-series aluminum alloy and a preparation method of the water-based soaking corrosion inhibitor. The preparation method comprises the following steps that S1, 20-100 parts of deionized water is taken; s2, sequentially adding 4-20 parts of an oxidant, a pro-oxidant, a complexing agent, an inorganic film-forming agent, an organic film-forming agent and a pH regulator; and S3, the pH value is adjusted to 6.5-7.5, stirring is conducted till complete dissolution is achieved, and the water-based 7-series aluminum alloy soaking corrosion inhibitor is obtained. 一种水基7系铝合金浸泡缓蚀剂及其制备方法,特别涉及一种用于7系铝合金在CNC、抛光或者阳极氧化等表面处理过程中水基浸泡缓蚀剂及其制备方法,包括如下步骤:S1:取去离子水20-100份;S2:依次加入4-20份氧化剂、助氧化剂、络合剂、无机成膜剂、有机成膜剂、PH调节剂;S3:调节pH值至6.5-7.5,搅拌至完全溶解,得到水基7系铝合金浸泡缓蚀剂。
