Abstract
The invention discloses a smokeless mirror face chemical polishing solution which is prepared from the following components in percentage by weight: 75-80% of phosphoric acid, 3-4% of sulfuric acid, 0.5-1% of a brightener, 0.8-1.2% of an oxidizing agent, 0.5-0.6% of a corrosion inhibitor, 0.1-0.3% of an accelerant, 0.05-0.07% of a catalyst and the balance of water. The smokeless mirror face chemical polishing solution in the polishing process does not generate any smoke, generates neither irritant nor potential toxic and harmful gas, and is free of environmental pollution. When the smokeless mirror face chemical polishing solution is used for polishing, the bright dipping speed is high, and the brightness value is nearly consistent with that of three-acid polishing. The smokeless mirror face chemical polishing solution is simple to operate, and in actual production, the relationship between temperature and time needs to be considered without considering other factors, so that the human cost of the manufacturer is lowered.
Description
Technical field
The invention belongs to chemical rightenning technical field, be specially a kind of smokeless minute surface chemical brightening solution.
Background technology
What be most widely used in the chemical rightenning of current aluminium is exactly the three acid polishing that phosphorus acid-sulfur acid-nitric acid forms.The mass ratio of phosphorus acid-sulfur acid-nitric acid is roughly 6:3:1, and service temperature is greatly about about 100 DEG C.The fields such as household electrical appliances, automobile, bathroom, door and window, electronics, ornaments are widely used in because aluminium has well ornamental after chemical rightenning.
But due to the strong oxidizing property of nitric acid, volatility and unstable when being reduced, make nitric acid transporting filling, tank liquor configuration, dailyly to add, heat up heating, production operation time there is many potential safety hazards and harm.Particularly in aluminium polishing operation process, nitric acid by aluminium strong be reduced into poisonous and hazardous NO
2tobacco, causes body and mind to injure to operator, causes corrosion simultaneously to equipment, to environment.Meanwhile, nitric acid constantly consumes along with the carrying out produced, and adding by rule of thumb is often difficult to ensure that product quality consistently.
Summary of the invention
The object of the present invention is to provide that a kind of polishing brightness is high, easy and simple to handle, in actual production without the smokeless minute surface chemical brightening solution of obnoxious flavour.
The technical solution used in the present invention:
A kind of smokeless minute surface chemical brightening solution, be by the phosphoric acid of 75 ~ 80% of weight percent, 3 ~ 4% sulfuric acid, the brightening agent of 0.5 ~ 1%, oxygenant, the inhibiter of 0.5 ~ 0.6%, accelerator, the catalyzer of 0.5 ~ 0.7 ‰ and the water of surplus of 0.1 ~ 0.3% of 0.8 ~ 1.2% be prepared from.
As preferably, the concentration of described phosphoric acid is 85%, and the concentration of sulfuric acid is 98%, and the mass values of phosphoric acid and sulfuric acid is not less than 20:1.
As preferably, described brightening agent is the mixture of barium titanate and cupric sulfate pentahydrate.
As preferably, described oxygenant is the mixture of the different nonanoyl of peroxidation two and acetone.
As preferably, described inhibiter is the mixture of N-alkyl thiourea and sodium polyphosphate.
As preferably, described accelerator is the mixture of magnesium sulfate and zinc sulfate.
As preferably, described catalyzer is reagent grade sulfuric acid europium.
A kind of preparation method of smokeless minute surface chemical brightening solution, it is characterized in that comprising the steps: by weight percentage the smokeless minute surface chemical brightening solution component be prepared to be put into temp. controllable reactor successively, heat to 70 ~ 80 DEG C, stir under the condition of constant temperature and make for 0.5 hour.
Compared with prior art, the advantage of a kind of smokeless minute surface chemical brightening solution of the present invention:
1) in aluminium polishing process, do not produce any flue gas, do not have pungency or potential poisonous and hazardous gas to produce, environmentally safe yet; 2) polishing fluid is good to aluminium compatibility, can to substitute in reality almost 95% three acid polishing liquid, produce huge environmental benefit and economic benefit; 3) go out ray velocity during polishing fast, brightness value and three acid polishing are almost consistent, and polishing texture is the same with three acid polishing, and stable components, effect are as one; 4) even if new polishing fluid is not added in long-time production, polishing brightness and texture also can be consistent all the time, significantly improve polishing product qualified rate; 5) simple to operate, only need taking into account the relation of temperature and time in actual production, without the need to considering other, saving employment cost for using producer.
Embodiment
Embodiment 1
Smokeless minute surface chemical brightening solution, the concentration of by weight percentage 75% be 85% phosphoric acid, 3% concentration be 98% sulfuric acid, 0.5% barium titanate and the mixture of cupric sulfate pentahydrate, the different nonanoyl of peroxidation two of 0.8% and the mixture of acetone, the N-alkyl thiourea of 0.5% and the mixture of the mixture of sodium polyphosphate, the magnesium sulfate of 0.1% and zinc sulfate, the level europium sulfate of 0.5% and excess water be made into 100% and put into temp. controllable reactor successively, heat to 75 DEG C, stir under the condition of constant temperature and make for 0.5 hour.And concentration is 85% phosphoric acid and concentration be 98% sulfuric acid is 20:1 at qualitative ratio.
Embodiment 2
Smokeless minute surface chemical brightening solution, the concentration of by weight percentage 80% be 85% phosphoric acid, 4% concentration be 98% sulfuric acid, 1% barium titanate and the mixture of cupric sulfate pentahydrate, the different nonanoyl of peroxidation two of 1.2% and the mixture of acetone, the N-alkyl thiourea of 0.6% and the mixture of the mixture of sodium polyphosphate, the magnesium sulfate of 0.3% and zinc sulfate, the level europium sulfate of 0.7% and excess water be made into 100% and put into temp. controllable reactor successively, heat to 80 DEG C, stir under the condition of constant temperature and make for 0.5 hour.And concentration is 85% phosphoric acid and concentration be 98% sulfuric acid is 20:1 at qualitative ratio.
By repeatedly putting into practice the alternative tradition of smokeless minute surface chemical brightening solution " three acid " polishing be prepared from, what in the brightening agent in polishing fluid, anhydrous cupric sulfate had both accelerated aluminium goes out ray velocity, reduce polishing time, simultaneously after aluminium is mentioned and left polishing fluid, barium titanate and aluminium material surface react film forming, protection gloss acid and alkali liquid excessive corrosion, the oxygenant of polishing fluid is the strong oxidation that the different nonanoyl of peroxidation two replaces nitric acid in three acid polishing, synergy is produced with inhibiter, control pit in polishing process, the generation of corrosion line trace, the degradation production of the different nonanoyl of peroxidation two is water and carbonic acid gas, the various component proportionss of polishing fluid are once determining, its polishing effect is also stablized thereupon, constantly use along with polishing fluid and add, its polishing brightness and texture more make people satisfied.
Above embodiment is only introduces preferred case of the present invention, to those skilled in the art, not deviating from any apparent changes and improvements of carrying out in the scope of spirit of the present invention, all should be regarded as a part of the present invention.
