Domain more particularly to a kind of preparation method of green alkaline admiro complexing agent.
Background technique
Admiro is a kind of anti-corrosion coating for nearly twenty or thirty year just causing to pay attention to extensively.Currently, main anode is anti-
Shield property coating is zinc coat, but the raising of the needs and industry requirement with national industry upgrading, and traditional monometallic coating is not
It is able to satisfy existing demand, compared with other alloys, admiro has higher anti-corrosive properties, wear resistance and thermal-shock resistance；
Thus by extensive concern both domestic and external and application, shared specific gravity is also increasing in protective coating.
Admiro has the advantage that (1) excellent corrosion resistance compared to other monometallic coating.Nickeliferous 10% or less
Zn-ni alloy deposits it is 3~5 times higher than the zinc coat corrosion resistance of stack pile；Nickeliferous 10%~16% alloy layer is (most preferably
13%) 6~10 times higher than zinc coat, also superior to cadmium and cadmium titanium alloy.(2) excellent mechanical performance.Do not change steel after plating
Yield strength, tensile strength and elongation, plasticity are good.Cadmium plating layer, notch pull test are comparable in torsion-pull test
It is outstanding for cadmium coater on space flight neighborhood with satisfied low hydrogen brittleness.(3) excellent soldering.Under various conditions all
It is easy welding, while without the disadvantage of long whisker.(4) small to workpiece corrosion, coating internal stress is small.(5) solution dispersibility,
Covering power is good, coating is bright smooth.
Currently, environmentally friendly alkaline zinc-nickel alloy additive in the market is largely imported product, price is higher；Domestic adds
Add agent manufacturer to be mostly used organic amine and sodium potassium tartrate tetrahydrate etc. to use as alkaline zinc-nickel alloy complexing agent, performance is not sufficiently stable, plating
The nickel content of the alloy layer of formation also has biggish difference, so market in urgent need one kind is cheap, the alkali of function admirable
Property Zinc-nickel alloy electroplating complexing agent and corresponding additive product.
China Patent Publication No. CN105350037A discloses a kind of alkaline non-cyanogen galvanization nickel alloy plating solution, consisting of sulphur
Sour 5~200g/L of zinc, 1~150g/L of nickel sulfate, 5~435g/L of potassium carbonate, main 20~400g/L of complexant, auxiliary complexing agent 5
~300g/L, wherein main complexant is hydantoins and its derivative, and auxiliary complexing agent is organic amine, organic acid and its salt, gathers
The one or more of ethylene glycol, sulphite, urea or thiocarbamide etc.；The admiro of available nickel content 10%~16% plates
Layer.United States Patent (USP) US20050133376A1 discloses a kind of Electroplate liquid of alkaline zinc-nickel alloy, and group becomes 1~100g/L of zinc, nickel
0.1~50g/L, at least one nickel ion complexing agent and at least one 0.1~50g/L non-ionic polyoxyethylene ether surface active
Agent, complexing agent are one or more of aliphatic amine polymer, ethyleneamines or polyethyleneimine of low molecular weight, available to contain
There is the alloy layer of a large amount of γ crystal phases.
For Electrodeposition of Zn-ni Alloy In Alkaline Bath system, the complexing agent mainly used is mostly organic amine or polyphosphinates
(HEDP) etc., the concentration of such complexing agent is high, strong toxicity, although zn-ni alloy deposits can be obtained, in coating, nickel content is not
It is easy to control, it may also result in the eutrophication of water quality after discharge of wastewater, irreversible harm can be caused to environment, be not suitable for big
Range applications.
Summary of the invention
In order to overcome the shortcomings of Related product in the prior art, the present invention proposes a kind of green alkaline admiro complexing
The preparation method of agent, by carrying out structural modification, the organic compound synthesized, thus it is possible to vary the deposition of nickel ligand to organic amine
Current potential, make the sedimentation potential of nickel complex and Zn complex further to, can not only make the equilibrium potential of metal ion to
Negative direction is mobile, moreover it is possible to increase cathodic polarization, improve current efficiency to a certain extent；This complexing agent is used directly for Alkaline Zinc
In the zinc-plated conversion to admiro of hydrochlorate, it is not necessary to prepare plating solution again, save the cost, intermediate synthetic method is simple, does not make
With autoclave, it is not related to pyroreaction, is conducive to industrialization.
The present invention provides a kind of preparation methods of green alkaline admiro complexing agent, including following component: 50~
The p-hydroxyphenylhydantion of the cis-butenedioic anhydride of 200g/L and the reactant of organic amine and 2~10g/L.
