Description
Technical field
Zinc agent is sunk without cyanogen, the aluminum alloy cyanide-free in more particularly to a kind of plating applied to aluminium wheels sinks the present invention relates to one kind
The production method of zinc agent.
Background technology
In aluminium wheels plating, due to the presence of aluminium wheels matrix surface natural oxide film so that matrix covers with its surface
The bond strength of cap rock is very poor.To solve this problem, the heavy zinc processing of generally use, heavy zinc is the various pre-electroplating treatment sides of aluminum component
It is the easiest in method, economical, and industrial most commonly used technique.Zinc layers are plating, the good coating excessively of chemical plating.Nation obtains
Your method makes heavy zinc solution multi-element alloyed, changes the adhesion of coating, while the heavy zinc solution containing cyanogen dominates market always, because
The presence of cyanide can obtain the heavy zinc layers more smooth, fine and close, uniform and tiny particle than zincate is used alone, but cyaniding
Thing meets acid production hydrogen cyanide, and high risks are brought to environment and operator's health.
Traditional aluminium wheels electroplating technology includes treatment before plating, twice heavy zinc, nickel preplating/preplating non-cyanogen high-density copper, acid
The step of property bright copper plating, polishing, pre-treatment and multi-layer nickel-plating chromium.Chinese patent application CN101063217A discloses a kind of nothing
Cyanogen high-density copper electrolyte, and the nickel preplating step of traditional handicraft is replaced with preplating non-cyanogen high-density copper, cost is not only reduced,
Improve the quality of coating.But still using there is cyanogen to sink zinc technology in above-mentioned aluminium wheels electroplating technology.
The content of the invention
For existing technical deficiency, the present invention provides the heavy zinc agent of aluminum alloy cyanide-free in a kind of plating applied to aluminium wheels
Production method.
To achieve these goals, the technical solution used in the present invention is：A kind of aluminium in the plating applied to aluminium wheels

The aqueous solution of at least one of bipyridyl and sulfosalicylic acid component, the concentration of regulator is 150-250g/L；
The replenishers are containing at least one of sodium hydroxide, potassium hydroxide, sodium gluconate and sodium potassium tartrate tetrahydrate
The aqueous solution of component, the concentration of replenishers is 400-550g/L.
Hydroxide ion is provided by sodium hydroxide, one kind of potassium hydroxide or their mixture in described open cylinder agent
's；Copper ion is provided by least one of copper sulphate, copper chloride, copper nitrate and basic copper carbonate；Iron ion is by trichlorine
Change what at least one of iron, ferric sulfate and ferric nitrate provided；Nickel ion is by nickel chloride, nickel sulfate, nickel nitrate and nickel sulfate
What at least one of ammonium provided；Zinc ion is provided by least one of zinc oxide, zinc chloride and zinc sulfate.
Beneficial effects of the present invention：The present invention replaces the technique of cyanide using multicomponent complex additive, without cyaniding
Thing and strong complexing agent, nontoxic, wastewater treatment is simple, is the process for cleanly preparing that current country promotes with pressure energetically.With
The heavy zinc technology of traditional cyanide is compared, and a 3000L heavy zinc groove, 1 year Cymag that can save 500Kg, is reduced
The processing of 400m3 cyanide containing wastewaters；The present invention without cyanogen sink zinc technology than existing commercial type without cyanogen sink zinc crystallization more
Careful, adhesion more preferably, can be followed by the heavy zinc of cyanogen and compare favourably completely；The present invention without cyanogen sink zinc technology can use nickel preplating and
Preplating non-cyanogen high-density process for copper carries out the follow-up plating production of aluminium alloy, substitutes traditional cyanide electroplating technology completely, real
Now clean manufacturing truly.
