Abstract

The invention discloses a steel derusting / phosphating solution which is prepared from the following raw materials: 80-85 parts of phosphoric acid, 32-35 parts of hydrochloric acid, 12-15 parts of tartaric acid, 8-12 parts of ammonia water, 6-8 parts of carboxylic acid, 5-6 parts of stearic acid, 4-5 parts of ferric oxide, 6-7 parts of aluminum hydroxide, 7-8 parts of zinc powder, 5-6 parts of zinc hydroxide, 2-3 parts of anhydrous cupric sulfate, 5-6 parts of dimethyl fumarate, 3-5 parts of silicon oil, 4-6 parts of formic acid, 5-6 parts of carrageenin, 5-6 parts of glycerol, 3-5 parts of iron powder, 3-6 parts of copperas powder, 5-6 parts of oxalic acid, 3-5 parts of succinic acid, 3-6 parts of thiocarbamide and 3-5 parts of disodium edetate. The steel derusting / phosphating solution has favorable derusting effect, can form an anticorrosive coating on the metal surface, especially can treat the rusty steel surface to remove rust, and forms a smooth and compact phosphate coating on the treated metal surface, thereby achieving the effect of preventing metallic corrosion.

Description

technical field [0001] The invention relates to the technical field of a phosphating solution, in particular to a phosphating solution for iron and steel rust removal for metal surface treatment. Background technique [0002] Metal surfaces, especially steel surfaces, will rust due to oxidation and corrosion when in contact with the surrounding medium. The main components of the rust layer are metal oxides or hydroxides, etc. Such a rust layer structure is loose, porous, and hygroscopic, thereby accelerating the corrosion rate of metals and rapidly destroying metal products. [0003] At present, the existing methods for treating metal surfaces not only have complex procedures, high labor intensity (especially for the treatment of rusted metal components), low efficiency, but also pollute the environment. Especially after derusting, metal components are faced with the problem of rusting again, and antirust treatment or anticorrosion treatment is required. Contents of the ...
