Description
Technical field
The present invention relates to the technical fields of electrolytic copper foil manufacture, more particularly, to a kind of anti-oxidation liquid of Chrome-free of electrolytic copper foil
I.e. without the anti-oxidation technique of washing.
Background technique
Traditional electrodeposited copper foil forming manufacturing process specifically includes that generation copper foil-copper foil removing-drying-is anti-oxidation
Drying-winding before processing-washing-water of compaction-winding.In anti-oxidation treatment process, existing antioxidant is generally
Acidic chromate, after metal is contacted with chromating agent, surface be partly dissolved and in the form of metal-chromated oxide again
Precipitating.
Easily there are the problem of appearance such as wrinkle, water spot, color difference when producing ultrathin electrolytic copper foil in this production process distance.
Moreover, using oxidation proof passivation liquid containing chromium, there is also following shortcoming and defect:
(1) chromium of human carcinogen can be damaged to operator's body by containing；(2) after use, some copper foil products
High temperature oven is needed to dry, and high temperature causes the winding room temperature of sealing especially high, is not suitable for personnel's operation；(3) it needs anti-
Anode plate is added in copper foil smooth surface and hair side in oxidation trough, and leads to certain electric current just and can guarantee anti-oxidation requirement；(4) some oxygen
Change in passivating solution and contain zinc, forms metallic zinc in copper foil surface after electro-deposition, zinc simple substance can form original under battery Inner electrolysis matter
Battery, reduces the capacity and charge-discharge performance of battery, or even sets off an explosion.
In addition, also need after carrying out anti-oxidation processing using the oxidation proof passivation liquid containing chromium by washing, and the dress of washing
It sets including 1 pump and 4 jet pipes, needs to expend a large amount of electric energy and industrial water, subsequent also to generate waste water, this is not only polluted
Environment, and will increase cost of water treatment.
For save the cost and protection environment, it is necessary to existing anti-oxidation passivator and washing process are optimized and
It improves.
Summary of the invention
In order to solve the above problems existing in the present technology, it the present invention provides a kind of anti-oxidation liquid of Chrome-free, is free of
There is the chromium to human carcinogen and reduce the zinc simple substance of battery performance, and do not need to wash, will not be generated in the process
Contaminated wastewater environment, not only environmental protection but also saved cost.The present invention also provides use the anti-oxidation liquid of the Chrome-free without washing oxygen
Chemical industry skill, the technique are formed by passivating film and are consistent, and guarantee that electrolytic copper foil has good wellability and electric conductivity, and
Easy to operate, control is convenient, reduces the process of one of washing, energy saving, and will not generate the waste water of pollution environment.
To achieve the goals above, the present invention provides the following technical scheme that
A kind of anti-oxidation liquid of the Chrome-free of electrolytic copper foil includes following components: sodium tungstate 5-9g/L, 1-hydroxy ethylidene-1,1-diphosphonic acid 1-3g/
L, disodium ethylene diamine tetraacetate 4-7g/L and phosphatase 11-3ml/L.
In the anti-oxidation liquid of the Chrome-free, the addition of sodium tungstate can improve the surface roughness of copper foil, make it anti-oxidation
In treatment process, uniform passivating film is formed.
1-hydroxy ethylidene-1,1-diphosphonic acid, referred to as HEDP are a kind of organic phosphorus acids anti-incrustation corrosion inhibitors, can be more with iron, copper, zinc etc.
Metal ion species form stable complex compound, can dissolve the oxide of metal surface.Studies have shown that HEDP is remained at 250 DEG C
Play the role of good corrosion-mitigation scale-inhibition, still very stable at a high ph, not facile hydrolysis is not easily decomposed under general light and heat condition.It is resistance to
Acid-base property, the more other organic phosphoric acids of chlorine-resistant oxidation susceptibility (salt) are good.HEDP can be formed with underwater gold category ion, especially calcium ion
Six annulus chelates, thus HEDP has preferable scale inhibition effect and has apparent threshold effect, when compound with other water treatment agents
In use, showing ideal synergistic effect.
Disodium ethylene diamine tetraacetate, referred to as EDTA-2Na are a kind of good compounding agents in chemistry, and there are six coordinations for it
Atom almost can form stable chelate with all metal ions.
The main function of phosphoric acid is the pH value adjusted in anti-oxidation liquid, plays anti-oxidation liquid under the condition of suitable pH anti-
Oxidative deactivation effect.
The present invention is by the selection to said components, and preferably its proportion, by sodium tungstate, 1-hydroxy ethylidene-1,1-diphosphonic acid, second two
Amine tetraacethyl disodium and phosphoric acid are formulated in same solution system, and are acted synergistically, and can be formed uniformly in electrolytic copper foil surface
Polymerization be complexed film, the passivation film in many solvents stablize and it is insoluble, have good anticorrosive protective effect.
It include following components: sodium tungstate 6g/L, 1-hydroxy ethylene-1,1-diphosphonic as further describing for technical solution of the present invention
Sour 2g/L, disodium ethylene diamine tetraacetate 5g/L and phosphoric acid 2ml/L.
As further describing for technical solution of the present invention, the pH of the anti-oxidation liquid of Chrome-free is 2-4, invention human hair
Existing, the pH of anti-oxidation liquid is controlled in 2-4, and the passivating film that copper foil surface is formed is uniform, and no color differnece.
The present invention also provides the use anti-oxidation liquid of above-mentioned Chrome-free without the anti-oxidation technique of washing, comprising the following steps:
