Description
Technical field
The present invention relates to coating chemistry strip technical fields, and in particular to a kind of environment-friendly type tin copper coating decoating liquid and its moves back
Electroplating method.
Background technology
Since the influence factor that electroplating process is related to is too many, so, many Electroplate Factories can run into during plating
Various unqualified coating.In addition, in electroplating process, coating can be also deposited on hanger.Underproof coating needs to recycle profit
With, cost is reduced, and the coating on hanger needs to reuse after stripping, therefore, in electroplating industry, strip is very important
One link.
In electroplating process, particularly in the preparation process of wiring board, tin plating protection is carried out again after generally requiring first copper facing,
Tin copper coating on underproof tin copper coating and hanger needs stripping, the decoating liquid demand of this respect completely very high.
In traditional withdrawal plating, often require to use nitric acid to carry out strip, and the application of nitric acid in the industry can generate tobacco and
Workers ' health is damaged, therefore, it is possible to substitute nitric acid, become very urgent using upper more environmentally-friendly decoating liquid.
It is proposed in CN201610832836.7 and nitrobenzoic acid sodium has been used to carry out strip, tool to gun-metal layer as the main salt of strip
There is preferable effect.However, in practical applications, tin layers protection is often carried out outside layers of copper, is two individual coating；Greatly
The use of the nitrobenzoic acid sodium of amount, not only can greatly improve strip cost, and the plating solution after strip can also be made to become difficult.
The content of the invention
For problems of the prior art, the present invention provides a kind of environment-friendly type tin copper coating decoating liquid and its strip side
Method, it is of low cost, strip is efficient, stripping is clean using hydrogen peroxide sulfuric acid system decoating liquid；Without using raw materials such as nitric acid, make
Pernicious gas, more environmentally-friendly green are not generated with process.
In order to achieve the above objectives, the present invention proposes following technical scheme：A kind of environment-friendly type tin copper coating decoating liquid, every 1 liter
Component and its content in the environment-friendly type tin copper coating decoating liquid is as follows：

Wherein, the component in the every 1 liter environment-friendly type tin copper coating decoating liquid and its content are as follows：
The present invention also provides a kind of environment-friendly type tin copper coating strip method, the strip method includes pickling, washes, moves back
Plating, washing, baking step.
The environment-friendly type tin copper coating strip method is moved back using any environment-friendly type tin copper coating of claim 1~7
Plating solution is as follows：First the plating piece for being coated with tin copper coating is put into 5% dilute sulfuric acid and is impregnated 1-3 minutes；It is washed with water
Dilute acid soln；Then plating piece being put into 40 DEG C of the environment-friendly type tin copper coating decoating liquid, alignment coating inflate strip,
0.5-5 minutes strip time；It washes, dry after strip.
The present invention adds in strip accelerating agent, property is stablized, at low cost using hydrogen peroxide sulfuric acid system decoating liquid in system
It is honest and clean, the tin copper coating of substrate surface effectively can be quickly stripped, strip effect is good, efficient, and stripping is clean；Without using originals such as nitric acid
Material, pernicious gas, more environmentally-friendly green non-pollution are not generated using process.Coordinate again with the strip method of the present invention, strip effect
Fruit is good, efficient.
