Abstract
A Zn-Sn alloy plating liquid for plating on metal surface is prepared from zinc chloride and stannous chloride as main salts through respectively adding disodium ethylenediamine tetraacetate as zinc salt complexing agent and NH as tin salt complexing agent4F. Dissolving and complexing nitrilotriacetic acid and distilled water, and then mixing. The invention can be prepared and used at normal temperature, has stable performance, does not pollute the environment, has simple process and energy saving, can plate the inner surface and the outer surface of a workpiece, has bright and compact plating layer which is blue-white or silvery-white, and resists the corrosion of dilute acid and alkali. The application is wide.
Description
A kind of matallic surface layer Zinc-tin alloy solution and preparation technology thereof.
Conventional electro-galvanizing tin alloy solution contains prussiate, and is bigger to human body and environmental hazard.The service temperature height, energy consumption is big, and the many zinc of coating tin of acquisition are few, and cost is higher.
The purpose of this invention is to provide a kind of Zn-Sn alloy electroplating bath and preparation technology thereof, accomplish can to prepare and use under the normal temperature, save energy, free from environmental pollution.
The present invention is to be main salt with zinc chloride and tin protochloride, adds complexing agent and forms.The proportioning of each component is as above:
Zinc chloride ZnCl
220~45 grams per liters
Tin protochloride SnCl
22H
2O 5~20 grams per liters
Zinc salt complexing agent disodium ethylene diamine tetraacetate C
10H
14N
2O
8Na
22H
2O 20~40 grams per liters
Pink salt complexing agent NH
4F or NaF 5~25 grams per liters
Nitrilotriacetic acid(NTA) N (CH
2COOH)
35~10 grams per liters
All the other are distilled water or deionized water PH=2~55
Preparation technology of the present invention is as follows:
A, in plastic channel, pour into part distilled water or deionized water.Pei Zhi volume (as follows) adds zinc salt complexing agent disodium ethylene diamine tetraacetate by 20~40 grams per liters as required, constantly be stirred to dissolving fully after, go into zinc salt ZnCl by 20~45 grams per liters
2Dissolve complexing.
B, be equipped with nitrilotriacetic acid(NTA) N (CH by 5~10 grams per liters
2COOH)
3, pack that another has in the water plastic tank and with strong aqua or sodium hydroxide and adjusts to PH=4~5 into, add pink salt complexing agent NH by 5~25 grams per liters then
4F or NaF are stirred to dissolving fully, add pink salt SnCl by 5~20 grams per liters
22H
2After O dissolves complexing.All pour in the plastic channel and mix.
C, adding distil water or deionized water and are adjusted to PH=2~5.5 with HCl or NaOH solution and are got final product to the volume that needs preparation in the plastic channel.
In order to make effect of the present invention better, also can in plating bath, add micro-sea-gull washing composition.
Using method of the present invention is as follows: at normal temperatures workpiece is put into plating bath, with the electrolysis zine plate of different table area and sheet tin as anode.Be negative electrode with the workpiece and pass to 0.1~1A/Dm
2Low-voltage DC, just can be on the workpiece outside surface be electroplated the fine and close coating of light.On pipe fitting or inner walls of deep holes, obtain coating if desired, can penetrate aluminium bar in the workpiece and be suspended on the negative electrode, just can make and all obtain coating on workpiece inwall and the outside surface.
Compared with the prior art, the present invention has following characteristics:
1, can prepare and use at normal temperatures, stable performance, no waste gas produces, and is free from environmental pollution, do not damage human body.
2, preparation technology and using method are simple, and energy consumption is few, and the cost that obtains coating is low.
3, both the workpiece outside surface can be plated, the workpiece inwall can be plated again.Fine and close blue or green light of amount of coating light or silvery white, anti-diluted acid caustic corrosion, of many uses.
