Problems solved by technology

[0002] The pull ring of cans is generally made of electro-tinned steel plate. Although the electro-tinned steel plate has excellent tensile strength, after the steel plate is stamped and formed, the incision is prone to rust, especially in oxygen-containing water, oxidizing acid and containing CN-, Coordination ions can be formed in the solution of NH4+, and the degree of surface oxidation is extremely high, resulting in serious corrosion

Abstract

The invention discloses a surface treating agent, for a steel plate used for a zip-top can pull ring, with excellent oxidation resistance. The surface treating agent comprises, by weight, 20-45 parts of modified benzotriazole, 20-35 parts of vanillin, 5-15 parts of etidronic acid, 8-17 parts of 1-formyl-3-thiosemicarbazide, 8-15 parts of benzoic acid, 5-15 parts of medlar acid, 4-12 parts of ethylenediaminetetraacetic acid, 5-18 parts of zinc sulfate, 5-10 parts of anhydrous copper acetate, 2-3.5 parts of anionic polyacrylamide, 1-5 parts of nano-active titanium dioxide, 2-8 parts of zirconium oxide particles, 3-8 parts of sodium hydroxide and 150-220 parts of water. According to the surface treating agent, the treated steel plate is uniform in color and excellent in oxidation resistance.

Description

technical field [0001] The invention relates to the technical field of copper wire for cables, in particular to a steel plate surface treatment agent for pull rings of pop cans with excellent oxidation resistance. Background technique [0002] The pull ring of cans is generally made of electro-tinned steel plate. Although the electro-tinned steel plate has excellent tensile strength, after the steel plate is stamped and formed, the incision is prone to rust, especially in oxygen-containing water, oxidizing acid and containing CN-, Coordination ions can be formed in the solution of NH4+, and the degree of surface oxidation is extremely high, resulting in serious corrosion. Contents of the invention [0003] The invention provides a steel plate surface treatment agent for pull rings of pop cans with excellent oxidation resistance. The treated steel plate has uniform color and excellent oxidation resistance. [0004] A steel plate surface treatment agent for pull rings of po...
