Description
Technical field
The present invention relates to field of metal surface treatment technology, and in particular to a kind of chemical polishing of brass red copper welding material
Liquid and its application method.
Background technique
Polishing is generally divided into mechanical polishing, electrochemical polish and chemical polishing three classes, can not only remove table by polishing
Surface oxidized skin can also make workpiece surface more smooth, even up to mirror effect.
Mechanical polishing is to obtain glossy surface, shape of this method to workpiece by the phase mutual friction between abrasive material and substrate
Shape requires, and commonly used in the material of flat surface, if material shape is complicated, especially there is the material of corner angle, is difficult to use
This method.Electrochemical polish is so that material surface is reached smooth by point discharge principle, and the use needs of this method disappear
Consume a large amount of electric energy, higher cost, and if material has corner angle, it is likely to result in the state that corner angle flatten.Chemical polishing then may be used
To overcome these problems, power supply is not needed, surfacing processing can be carried out to complex-shaped material, polishing uniformity is good, behaviour
Make method simplicity, high production efficiency.
Traditional chemical polishing is using chromic acid, but since chromic acid is larger to environmental hazard, China's most places are
It is forbidden to use.The polishing method of substitution chromic acid is using " three acid " polishing, i.e. sulfuric acid, phosphoric acid, nitric acid, the technique polishing effect
Good, brightness is high, and still, in process of production, nitric acid can generate a large amount of tobacco, cause serious environmental pollution, while to operation
The health of personnel generates harm.Therefore the more and more chemical polishings that copper alloy is carried out using hydrogen peroxide-sulfuric acid system of people, are led to
Brightener is overregulated to reach brightness effect.However, it is necessary to which the workpiece of polishing treatment is not often single copper alloy merely, more
More may be the combination of a variety of alloys, existing since the condition of welding material and different-alloy during the polishing process is different
Technology can not make the welding materials such as red copper, brass alloys or even stainless steel while polishing reaches brightness effect.
Summary of the invention
In view of the above problems, the present invention provides a kind of chemical polishing solution for brass red copper welding material, mainly solve
The chemical polishing of the two or more different-alloy materials such as brass-red copper welding material, brass-red copper-stainless steel welding material.
In order to achieve the above objectives, the technical scheme is that
It is a kind of for brass-red copper welding material chemical polishing solution, the chemical polishing solution is by polishing fluid A and light-emitting solution

Sulfate, soya-bean oil base propane diamine sulfate, tallow alkyl propane diamine sulfate, tallow alkyl two sub- third triamine sulfate, butter
One or more of the sub- third triamine sulfate of alkyl Sanya the third tetramine sulfate, dodecyl two mixture.
The present invention also provides the above-mentioned application method for brass-red copper welding material chemical polishing solution, the uses
Method the following steps are included:
A, brass-red copper welding material is immersed in polishing fluid A and carries out chemical polishing；
B, the brass after polishing-red copper welding material is placed in light-emitting solution B and carries out out light processing.
Preferably, the application method further includes that welding material is carried out oil removing cleaning before step A.
Preferably, the application method further includes that will go out the welding material after light to be passivated processing after stepb.
Preferably, described to be used for brass-red copper welding material, Huang for brass-red copper welding material chemical polishing solution
The chemical polishing of the two or more different-alloy materials such as copper-red copper-stainless steel welding material.
The present invention provides a kind of chemical polishing solution and polishing method for brass red copper welding material, and this method first need to
The workpiece to be polished, which is placed in polishing fluid, to be polished, then the workpiece after polishing is carried out to move back film, light processing out.
The sulfuric acid less than 1% is used only as acidizing reagent in polishing fluid A of the invention, is corroded in copper alloy surface,
The unstable of system after metal dissolving is prevented between different-alloy, or is reacted to each other.The use for reducing sulfuric acid simultaneously, can drop
Reaction in low polishing trough reduces the release of heat, reduces the decomposition of hydrogen peroxide, reduces application risk, while extending throwing
The service life of light liquid.
Compared with existing chromic acid, three acid polishing system, this method does not use the chemical substance such as chromic acid harmful to environment,
Nitric acid is not used, tobacco, polishing process more safety and environmental protection will not be generated during the polishing process yet；Using lower dense in polishing fluid
The acid of degree can reduce the rate of reaction, reduce the heat that system generates, avoid the fast decoupled of hydrogen peroxide, extend throwing
The service life of light liquid；In polishing fluid A be added sulfuric acid amount be no more than 1%, the metal that can prevent different copper alloys from reflecting from
Phenomena such as son reacts on material surface, prevents the spot corrosion of material surface.
The present invention breaches the polishing method that classical acid adds hydrogen peroxide in use process, the dosage of acid is reduced to certain
Degree, can achieve the part of corrosion out-of-flatness, and can prevent the metal ion after different corrosion of copper alloy from mutually polluting,
Corrosion will not be generated to welding portion, influence weld strength, the environmentally friendly polishing method of different Cu alloy welding material may be implemented,
Brass portions after polishing are bright, and red copper part is bright, and welding position will not corrode, other welding materials are unaffected, reach
Good using effect.
