Abstract
The invention discloses composite coloured passivating solutions of a kind of environment-friendly type and preparation method thereof, belong to technical field of metal material surface treatment.The component and content of the passivating solution be：5 ~ 8 g/L tannic acid, 4 ~ 8mL/L titanium trichlorides, 4 ~ 7mL/L nitric acid, 15 ~ 20mL/L hydrogen peroxide, 2 ~ 5mL/L concentrated sulfuric acids, 8 ~ 12mL/L phosphoric acid, 2 ~ 7g/L sodium metasilicate, 6 ~ 10g/L potassium fluorides, 2 ~ 5mL/L ascorbic acid, 4 ~ 7mL/L aminotrimethylenes pitch phosphonic acids, remaining is water, and pH value is 1.5 ~ 2.0.Using passivating solution of the present invention treated zinc coating passivating film, color is bright, and color and thicknesses of layers are uniform, corrosion resisting property is excellent, and trivalent chromium, Cr VI and other harmful substances are free of in passivating solution, environment friendly and pollution-free, passivation technology is simple, and passivation efficiency is high, and membranous layer corrosion resistance is good.
Description
Technical field
The present invention relates to composite coloured passivating solutions of a kind of environment-friendly type and preparation method thereof, belong to metal material surface processing skill
Art field.
Background technology
Electrogalvanizing is anticorrosive metal a kind of commonly method, widely apply to hardware electromechanics, steamer, electronic equipment,
The various fields such as space flight, ocean platform.Since the corrosion potential of zinc is more negative than iron, and corrosion resistance is good in dry air, works as plating
When part contact corrosion medium, can first it react with zinc, to protect matrix.But since the property of zinc is active, damp and hot
Environmental condition under be easily corroded, if galvanized workpiece, without post-processing, coating just produce quickly by dimmed generations white corrosion
Object weakens the antiseptic property of zinc coat significantly, and matrix continues that corrosion generation red rust occurs over time, loses corrosion-resistant effect
Fruit.In order to improve steel corrosion resistance and decorative appearance performance, generally all processing can be passivated to workpiece again after zinc-plated, make plating
One layer of passivating film of part Surface Creation.
Cr6+Toxicity is high, easily carcinogenic, harmful to the health of people.Cr3+Although toxicity only Cr6+One thousandth, but long-term
Using with Cr can be also converted into transportational process6+, various regions government limited the use of chromate.2006, European Union issued
RoHS greens instruct, the stringent use for limiting chromium in electronic electric equipment making, at present and continuous perfect.
Based on environmental requirement, exploitation environmental type chromium-free deactivation has become the research heat of the various fields such as electroplating anticorrosion
Point.However silicate passivation has good application prospect, but the stability of passivating film and corrosion resistance are poor, need further perfect
Silicate systems；And molybdate passivation film effect is preferable, but its is of high cost；Rare-earth salts passivation is tied to form that this is also high, and technological operation
Complexity, efficiency are low；The film outward appearance of titanium salt passivation gained is sufficiently close to chromating, but corrosion resistance is poor can not show a candle to chromate.
Organic passivation corrosion resistance is preferable in common non-chromium inactivating technique, but adhesive force and heat resistance are poor, and single inorganic passivation is resistance to
Corrosion is slightly worse than organic passivation.
Invention content
The purpose of the present invention is to provide a kind of composite coloured passivating solution of environment-friendly type, the components and content of the passivating solution
For：5 ~ 8 g/L tannic acid, 4 ~ 8 mL/L titanium trichlorides, 4 ~ 7 mL/L nitric acid, 15 ~ 20 mL/L hydrogen peroxide, 2 ~ 5 mL/L are dense
Sulfuric acid, 8 ~ 12mL/L phosphoric acid, 2 ~ 7 g/L sodium metasilicate, 6 ~ 10 g/L potassium fluorides, 2 ~ 5 mL/L ascorbic acid, 4 ~ 7 mL/L ammonia
Base trimethylene pitches phosphonic acids, remaining is water, and pH value is the .0 of 1 .5 ~ 2.
The preparation method of the composite coloured passivating solution of environment-friendly type of the present invention, is as follows：It successively will be a certain amount of
Phosphoric acid, nitric acid, tannic acid, titanium trichloride, hydrogen peroxide, sodium metasilicate, potassium fluoride, phosphoric acid, ascorbic acid, aminotrimethylene pitch phosphine
Acid is add to deionized water uniformly mixed, adds water constant volume to required volume to get environment-friendly type Organic-inorganic composite chromatic passivation
Liquid.
