Low-chromium high-corrosion-resistance army green passivation solution

The invention belongs to the technical field of passivation solutions, and particularly relates to a low-chromium high-corrosion-resistance army green passivation solution. The army green passivation solution comprises a component A and a component B, wherein the volume ratio of the component A to the component B is 1: 1; the component A comprises the following components: chromic anhydride, a three-acid mixed solution and an accelerant; and the component B comprises a film-forming agent. A passivation film layer of the passivation solution is thick and uniform in thickness and consistent in color and gloss, and all performance indexes of the passivation solution are superior to those of white passivation, colored passivation and the like. And moreover, the passivation solution disclosed by the invention can ensure that the color of a film layer is uniform and unchanged, and the service life of the passivation solution is well prolonged. 本发明属于钝化液技术领域，尤其涉及一种低铬高耐蚀军绿色钝化液。本发明所述军绿色钝化液包括组分A和组分B，所述组分A和组分B的体积比为1:1；所述
