Description
Technical field
The present invention relates to polishing fluid category, more particularly to a kind of aluminum alloy chemically polishing fluid and preparation method thereof and buffer
Skill.
Background technology
Due to workability energy and its surface high-corrosion resistance after treatment of aluminium and aluminium alloy, more and more
Al-alloy products be used in civilian and industrial goods.In order to improve the decoration performance of Al-alloy products, need to its surface
Carry out various process, wherein chemical polishing is a kind of to give aluminum alloy surface noble beautiful handling process.
The sour chemical polishing solution of traditional three is made up of 70% phosphoric acid, 20% sulfuric acid, 10% nitric acid.In this polishing fluid
Nitric acid acts as a kind of effect of corrosion inhibiter, nitric acid have oxidisability using when reacted and be reduced into brown color with aluminium
Nitrogen dioxide gas, nitrogen dioxide can be caused serious injury to the respiratory system of operating personnel, while nitrogen dioxide is also rotten
Plant equipment in erosion factory.Typically carry out at 100 DEG C or so additionally, due to three acid polishing operation, nitric acid is volatile and divides
Solution, the depletion rate of usual nitric acid are too fast, frequently its content need to be analyzed and add, cause between Al alloy parts batch
Gloss fluctuation larger, be also unfavorable for transfer matic continuity operate.
With the reinforcement of environmental consciousness and regulation, increasing factory selects two acid polishing process at present.But two acid
There is problems with 3C Product production process：1., when in polishing fluid, aluminium ion concentration is more than 16g/L, polish with through hole
Or blind hole sandblasting workpiece when can produce polishing gas trace, polishing gas trace especially when sandblasting workpiece is for the aluminium alloy of Al5252 material
Become apparent from.2. when pair polishing through the plastic-aluminum combined part that T is processed, plastic-aluminum intersection easily occurs uneven, and working of plastics easily turns to be yellow.3.
Al alloy parts in automatic polishing line upthrow light during workpiece transfer the time required to generally more than 18 seconds, aluminium section bar
The time spent in throwing production line is shifted is longer generally more than 30 seconds, as the drop of polishing fluid plows meeting on surface in transfer process
Irregular current mark is formed, affects appearance.
Content of the invention
For above-mentioned deficiency, it is an object of the invention to provide a kind of polishing fluid without nitric acid, produces for 3C electron-like
The aluminium alloy of product and plastic-aluminum combined part, even if also polishing gas trace will not be produced when the aluminium ion concentration in polishing fluid reaches 40g/L,
While can also eliminate in two sour polishing fluids using the problem for forming current mark due to workpiece transfer on transfer matic, to plastic-aluminum combined
Part, can prevent plastic-aluminum glue interface uneven, and plastics turn to be yellow.Meanwhile, the present invention also provides the preparation method of above-mentioned polishing fluid and throwing
Light technique.
In order to solve above-mentioned technical problem, the present invention provides technical scheme below：A kind of aluminum alloy chemically polishing fluid, its bag
Raw material containing following mass percent：Phosphoric acid 50～80%, sulfuric acid 18～48%, lithium salts 0.1～0.2%, current mark inhibitor
0.3～0.5%, corrosion inhibiter 0.1-0.2%, water：Surplus.
In above-mentioned aluminum alloy chemically polishing fluid, described lithium salts can be lithium acetate, and lithium carbonate, in lithium hexafluoro phosphate
One kind.
In above-mentioned aluminum alloy chemically polishing fluid, described current mark inhibitor is tetrahydroxypropyl ethylenediamine, lauryl two
Methyl oxidation amine, alkyldimethylbenzylammonium amine, the mixture of one or more in piperazine.
In above-mentioned aluminum alloy chemically polishing fluid, described corrosion inhibiter is acid red, crystal violet, methylene blue, methylene
Base is green, toluidine blue, the mixture of one or more in methyl blue.
The present invention also provides the preparation method of aluminum alloy chemically polishing fluid as above, and lithium salts, corrosion inhibiter are added to
In water, component A is obtained；
The phosphoric acid of current mark inhibitor, the 1/8-1/5 for accounting for phosphoric acid total amount is mixed and heated to 50-60 DEG C, stirring a period of time
After obtain component B；
The phosphoric acid of sulfuric acid and surplus is mixed to get component C；
After component A, B, C temperature are less than 40 DEG C, component A, B are added to mixing in component C and are obtained final product.
In addition, the present invention also provides the glossing of a kind of aluminium and aluminium alloy, comprise the steps：(1), Al alloy parts
Or the Al alloy parts through mechanical sandblasting, degreasing degreasing is carried out, sufficient water is carried out to metal works after degreasing degreasing
Wash；(2), metal works carry out chemical polishing in the polishing fluid as described in Claims 1-4 is arbitrary, are washed after polishing；
(3), metal works are immersed except to remove insoluble metal oxide in stain dedusting agent, so as to obtain the metal watch of cleaning light
Face, after fully washing, drying can obtain the surface of uniform light in an oven.
Compared with prior art, the technical scheme that the present invention is provided has the advantage that：
1., during conventional two sour polishing fluid uses, after Al alloy parts polishing, transfer time can produce polishing more than 18 seconds
Current mark, the polishing fluid of the present invention, after workpiece polishing, transfer time will not produce current mark before 50 seconds.2.. general two acid polishing
Can produce polishing gas trace when the liquid polishing band logical hole workpiece of sandblasting or complex-shaped workpieces, the polishing fluid of the present invention, even if aluminium from
Sub- concentration reaches 40g/L and does not also result in gas trace.3. the plastic-aluminum combined part that pair nanometer is molded, general polishing fluid can be in plastic-aluminum Jiao Jie
Place's generation is grown dim uneven, and plastics jaundice easy to change, the polishing fluid of the present invention process after intersection and other position outward appearances equal
Even consistent, plastics nondiscolouring.
