Abstract

The invention discloses environmentally-friendly type pickling solution applied to an aluminium product. The environmentally-friendly type pickling solution comprises the following components: inorganic strong acid, a catalyst, oleic acid, persulfate, a surface active agent, red blood acid salt, ternary polycarboxylic acid, S-60, N, N-dimethylformamide and water. Persulfate serving as a strong oxidizing agent is added to form a dense protective film on the surface of the aluminium product; the catalyst is added to shorten the time forming the protective film, so that resource waste caused by the excessive corrosion phenomenon is avoided; red blood acid salt serving as a precipitator is added to reduce concentration of iron ions in the pickling solution so as to prolong the service life ofthe pickling solution, increase the repeated utilization ratio of the pickling solution and reduce environmental pollution and cost; and moreover, organic acid carboxylic acid, S-60 and N, N-dimethylformamide serving as acid mist inhibitors are added to prevent generation of smog, improve the protective effect of the protective film and further improve the corrosion inhibition effect of the surface of the aluminium product.

Description

technical field [0001] The invention relates to the technical field of pickling liquid, in particular to an environment-friendly pickling liquid applied to aluminum materials. Background technique [0002] Pickling liquid is mainly used for pickling and brightening treatment of aluminum, aluminum, and steel parts, which can remove oil, rust, brighten, passivate, rust, and suppress fog. It is especially suitable for cold rolling of aluminum The assembly line operation greatly shortens the cleaning time, and at the same time suppresses the generation of smoke, greatly improves the production environment, and greatly reduces the corrosion rate of metals. [0003] However, the traditional pickling solution mainly has shortcomings such as high acid content and poor recycling effect. In order to reduce environmental pollution and improve the recycling rate of the pickling solution, the present invention proposes an environmentally friendly pickling solution for aluminum materials ...
