Description
Technical field
The invention belongs to aluminium and technical field of aluminum alloy surface treatment, specifically a kind of not phosphoric acid, nitric acid, polishing
During will not produce aluminum alloy chemically polishing fluid of tobacco and preparation method thereof.
Background technology
Aluminium and its alloy are a kind of common metal materials in our daily lifes, and the processing technology of aluminum alloy materials is more
Plant various.Also because aluminium in our daily lifes in important application, it is desirable to aluminum products have different surface effects, such as it is soft
With sand face or bright mirror surface effect, polishing is exactly the important means for obtaining bright mirror surface.
Polishing to aluminium and its alloy typically uses mechanical polishing, three kinds of technologies of chemical polishing and electrobrightening.Wherein change
Optical polishing is metal chemical etching under given conditions, i.e. metal material surface in the corrosive agent of reasonable mixture ratio, oxidant, adds
Plus the series of chemical occurred in the polishing solution of agent composition, the uneven oxide-film in metallic microscopic surface or molten polishing
The consistence mucous membrane formed in liquid so that the dissolution velocity of microcosmic surface is uneven, and the dissolution velocity of microcosmic ledge is significantly big
Dissolution velocity at calixconcavity, this reduces the asperity on surface, so that metal surface smooth.Chemical polishing
With it is following the characteristics of：1. strong adaptability, can be processed by shot blasting to the product of different shape and unlike material；2. production technology
Simply, easy to operate and production efficiency, height is not required to power supply and special fixtures, low production cost.
During traditional three acid polishing, due to containing substantial amounts of nitric acid in polishing fluid, therefore can be produced in polishing process a large amount of
Tobacco（That is oxynitrides）Severe contamination environment, endangers the health of people；Phosphoric acid also has a certain impact to environment simultaneously,
It is also easy to produce eutrophication.Because brightness and production that traditional three acid polishing is unable to reach without tobacco surface with chemical polishing technology will
Ask, this allows it to be above limited by very large in application.
The content of the invention
In order to overcome the deficiencies in the prior art, it is an object of the invention to provide it is a kind of it is not phosphorous, without tobacco, can normal temperature throw
Light, polishing time are short, polishing effect is good, suitable for the aluminum alloy chemically polishing fluid and preparation method thereof of siliceous aluminium alloy.
In order to solve the above technical problems, the present invention uses following technical scheme：
A kind of yellow fume-free aluminium alloy chemical polishing solution without nitric acid, the content of each component is as follows in the chemical polishing solution：

Water surplus.
The present invention is improving traditional three sour chemically polishing methods, the liquid based on citric acid, sulfonic acid, glacial acetic acid, with
Combined additive replaces nitric acid, while adding corrosion inhibiter.Combined additive is, by main brightener sodium polydithio-dipropyl sulfonate, to carry
Body brightener cocoanut fatty acid diethanolamide, auxiliary brightener Sodium Benzoate, nicotinic acid composition.Corrosion inhibiter be by molybdate,
Tungstates compounds composition with 2- sulfydryl -1- methylimidazoles three.
A kind of yellow fume-free aluminium alloy chemical polishing solution its preparation method without nitric acid, comprises the following steps：
（1）Constituted by the formula of raw material, sodium polydithio-dipropyl sulfonate, cocoanut fatty acid diethanolamide, Sodium Benzoate, cigarette
Acid etc. is soluble in water, is sufficiently stirred for that brightener A is obtained；
（2）Constituted by the formula of raw material, by citric acid, sulfonic acid, glacial acetic acid, molybdate, tungstates, 2- sulfydryl -1- methylimidazoles
It is dissolved in appropriate water, is sufficiently stirred for treating that its dissolving is obtained semi-finished product B；
（3）During brightener A slowly added into semi-finished product B, it is sufficiently stirred for being obtained being thrown without tobacco aluminum alloy chemically without nitric acid
