Abstract

The invention relates to treating fluid, and particularly relates to environmentally-friendly multifunctional metal surface treating fluid. The environmentally-friendly multifunctional metal surface treating fluid is mainly used for solving the technical problems in the prior art that when the treating fluid is used for treating metal surfaces, oil removal, dust removal and cleaning need to be carried out in advance, heating is also needed, operation working procedures are complicated, the conversion quality is low, the rust prevention capacity is low and the like. The treating fluid comprises the following components in percentage by mass: 25%-40% of phosphoric acid, 0.25%-0.32% of sheet zinc or zinc slab, zinc granules, 1%-1.5% of acid type manganese phosphate, 0.1%-0.15% of calcium nitrate, 0.8%-1% of tartaric acid, 0.2%-0.8% of phytic acid, 0.5%-0.7% of thiourea, 0.11%-0.16% of polyethylene glycol, 1.5%-2.5% of sodium dodecylbenzene sulfonate, 0.08%-0.12% of analytically pure ammonium molybdate and the balance of water.

Description

technical field [0001] The invention relates to a treatment liquid, in particular to an environment-friendly multifunctional metal surface treatment liquid. Background technique [0002] Coating is an anti-corrosion method widely used in metal surface treatment. Pre-painting treatment is an essential pre-painting process. Its function is to establish a non-metallic protective layer on the protected metal workpiece, so that the metal workpiece has good adhesion to the paint film, so that both Stronger adhesion, thus improving the corrosion resistance of the coating. Chinese patent discloses an environment-friendly multifunctional steel surface treatment solution (publication number: CN102839365 A), which is composed of phosphoric acid, film forming agent, organic acid, dispersant, oxidation accelerator, complexing agent, surfactant and other raw materials Composition, its specific raw material ratio is as follows: phosphoric acid (85%) 28-35% (percentage by weight), zinc di...
