Abstract
The invention discloses a kind of smokeless minute surface chemical polishing solution, it is prepared by the water of 75 ~ 80% phosphoric acid of percentage by weight, 3 ~ 4% sulfuric acid, 0.5 ~ 1% brightener, 0.8 ~ 1.2% oxidant, 0.5 ~ 0.6% corrosion inhibiter, 0.1 ~ 0.3% accelerator, 0.5 ~ 0.7 ‰ catalyst and surplus.The smokeless minute surface chemical polishing solution, any flue gas is not produced in polishing process, produced without excitant or potential poisonous and hazardous gas yet, it is environmentally safe；It is fast to go out ray velocity during polishing, brightness value is almost consistent with three acid polishing；It is simple to operate, the relation of temperature and time need to be only taken into account in actual production, without considering other, to save employment cost using producer.
Description
Technical field
The invention belongs to chemical polishing technical field, specially a kind of smokeless minute surface chemical polishing solution.
Background technology
What is be most widely used in the chemical polishing of current aluminium is exactly the three acid polishing of phosphorus acid-sulfur acid-nitric acid composition.
The mass ratio of phosphorus acid-sulfur acid-nitric acid substantially 6:3:1, operation temperature is about at 100 DEG C or so.Because aluminium is by chemistry
There is a good dicoration after polishing and be widely used in the fields such as household electrical appliances, automobile, bathroom, door and window, electronics, ornaments.
But the strong oxidizing property due to nitric acid, volatility and unstability when being reduced so that nitric acid transport it is filling,
Tank liquor configuration, it is daily add, heat up heating, production operation when many potential safety hazards and harm be present.Particularly polished in aluminium
In operation process, nitric acid by aluminium it is strong be reduced into poisonous and hazardous NO2Tobacco, body and mind is caused to injure operating personnel, simultaneously
Equipment is caused to corrode, environment is polluted.Meanwhile nitric acid constantly consumes with the progress of production, adding by rule of thumb
Often it is difficult to ensure that product quality is remained the same from beginning to end.
The content of the invention
It is an object of the invention to provide a kind of polishing, brightness is high, the nothing without pernicious gas in easy to operate, actual production
Cigarette minute surface chemical polishing solution.
The technical solution adopted by the present invention：
A kind of smokeless minute surface chemical polishing solution, is by 75 ~ 80% phosphoric acid of percentage by weight, 3 ~ 4% sulfuric acid, 0.5 ~ 1%
Brightener, 0.8 ~ 1.2% oxidant, 0.5 ~ 0.6% corrosion inhibiter, 0.1 ~ 0.3% accelerator, 0.5 ~ 0.7 ‰ catalyst
It is prepared with the water of surplus.
Preferably, the concentration of the phosphoric acid is 85%, the concentration of sulfuric acid is 98%, and the mass values of phosphoric acid and sulfuric acid are not
Less than 20:1.
Preferably, the brightener is the intermixture of barium titanate and cupric sulfate pentahydrate.
Preferably, the oxidant is the intermixture of two different nonanoyl of peroxidating and acetone.
Preferably, the corrosion inhibiter is the intermixture of N- alkyl thioureas and sodium polyphosphate.
Preferably, the accelerator is the intermixture of magnesium sulfate and zinc sulfate.
Preferably, the catalyst is reagent grade sulfuric acid europium.
A kind of preparation method of smokeless minute surface chemical polishing solution, it is characterised in that comprise the following steps：By weight percentage
The smokeless minute surface chemical polishing solution component being prepared is sequentially placed into temperature controllable reactor, 70 ~ 80 DEG C are heated up to, in constant temperature
Under conditions of stir 0.5 hour and be made.
Compared with prior art, the advantages of a kind of smokeless minute surface chemical polishing solution of the invention：
1）Any flue gas is not produced in aluminium polishing process, without excitant or potential poisonous and hazardous gas yet
Produce, it is environmentally safe；2）Polishing fluid is good to aluminium compatibility, can substitute in practice almost 95% three acid polishing liquid, produces
Huge environmental benefit and economic benefit；3）It is fast to go out ray velocity during polishing, brightness value is almost consistent with three acid polishing, polishes texture
As three acid polishing, stable components, effect such as one；4）Even if new polishing fluid is not added in production for a long time, polishing brightness and
Texture also can be consistent all the time, significantly improves polishing product qualified rate；5）It is simple to operate, in actual production only need to take into account temperature and when
Between relation, without considering other, for using producer save employment cost.
Embodiment
Embodiment 1
Smokeless minute surface chemical polishing solution, 75% concentration by weight percentage is 85% phosphoric acid, 3% concentration is 98% sulphur
Acid, 0.5% barium titanate and the intermixture of cupric sulfate pentahydrate, the intermixture of 0.8% two different nonanoyl of peroxidating and acetone, 0.5%
The intermixture of N- alkyl thioureas and sodium polyphosphate, the intermixture of 0.1% magnesium sulfate and zinc sulfate, 0.5% level europium sulfate and
Excess water is made into 100% and is sequentially placed into temperature controllable reactor, is heated up to 75 DEG C, stirs 0.5 hour and makes under conditions of constant temperature
Into.And concentration is 85% phosphoric acid and concentration is that ratio of 98% sulfuric acid in quality is 20:1.
Embodiment 2
Smokeless minute surface chemical polishing solution, 80% concentration by weight percentage is 85% phosphoric acid, 4% concentration is 98% sulphur
Acid, the intermixture of 1% barium titanate and cupric sulfate pentahydrate, 1.2% two different nonanoyl of peroxidating and intermixture, 0.6% N- of acetone
The intermixture of alkyl thiourea and sodium polyphosphate, the intermixture of 0.3% magnesium sulfate and zinc sulfate, 0.7% level europium sulfate and remaining
Amount water is made into 100% and is sequentially placed into temperature controllable reactor, is heated up to 80 DEG C, stirs 0.5 hour and be made under conditions of constant temperature.
And concentration is 85% phosphoric acid and concentration is that ratio of 98% sulfuric acid in quality is 20:1.
The alternative tradition of smokeless minute surface chemical polishing solution " three acid " being prepared by repeatedly putting into practice polishes, in polishing fluid
Brightener in anhydrous cupric sulfate both accelerated the ray velocity that goes out of aluminium, reduce polishing time, while polishing is lifted off in aluminium
After liquid, barium titanate and aluminium material surface reaction film forming, protect gloss not by acid solution excessive corrosion, the oxidant of polishing fluid is peroxidating
Two different nonanoyls replace the strong oxidation of nitric acid in three acid polishing, and synergy is produced with corrosion inhibiter, control fiber crops in polishing process
Point, the generation for corroding line trace, the catabolite of two different nonanoyl of peroxidating are water and carbon dioxide, the various composition ratio of polishing fluid
Once it is determined that, its polishing effect is also stablized therewith, and as polishing fluid continues on and adds, it polishes brightness and texture and more made one
It is satisfied.
Above example is only to introduce the preferred case of the present invention, to those skilled in the art, without departing substantially from this
Any obvious changes and improvements carried out in the range of spirit, it is regarded as the part of the present invention.
