Abstract

The invention discloses a flexible treatment liquid and a method for treating a pull ring material by using the same. The flexible treatment liquid comprises the following raw materials of magnesium fluoride, sodium tripolyphosphate, hexafluorozirconic acid, sodium fluorosilicate, hydrochloric acid, nitric acid, phosphoric acid, vinyl triethoxy silane, sulfuric acid, calcium nitrate, water, dialkyl peroxide, bicarbonate peroxide, propyl epoxy acrylate, nano silicon dioxide and aluminum oxide. Through reasonable proportioning, the flexible treatment liquid can solve the problems that in a traditional process, hexavalent chromium passivation is large in toxicity, and the chromium-free passivation is low in toxicity but the corrosion resistance is poor, meanwhile, the problems that the treatment of liquid medicine used when an organic film is coated on the surface of an inorganic film in a composite passivation process is complex, and the adhesive force is poor are solved, good corrosionresistance and fingerprint resistance are achieved, the effects of being strong in adhesive force, safe, non-toxic and simple in process are achieved, and therefore, the flexible treatment liquid is suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of surface treatment of metal materials, and in particular relates to a flexible treatment liquid and a method for treating a pull ring material. Background technique [0002] The pull ring material is mainly processed by aluminum substrate, and its thickness is 0.26-0.46mm. In order to improve the corrosion resistance and oxidation resistance of the pull ring material, the pull ring material should be passivated. [0003] At present, in the industrial production at home and abroad, the passivation of tinplate is carried out by chromate containing hexavalent chromium, but hexavalent chromium is very polluting to the environment and is a highly toxic substance, which is also very harmful to the human body. Strong carcinogenic effect, which is very harmful to human body and environment, especially the use of pull ring materials is generally applied to food and beverage cans, long-term use will cause irreversible damage ...
