Abstract
The invention relates to the technical field of machining of die-casting aluminum alloy parts, in particular to treating fluid used for treating the surface of a die-casting aluminum alloy part. The treating fluid is prepared from 20 parts of sodium polyphosphate, 20 parts of melamino-formaldehyde resin, 10 parts of N,N-dimethylacetamide, 5 parts of citric acid, 0.5 part of iridoid, 15 parts of ethyl alcohol and 50 parts of water. Formula design of the treating fluid is reasonable, especially a small amount of iridoid is added, and therefore the treating efficiency of the treating fluid can be obviously increased.
Description
Technical field
The present invention relates to aluminium diecast alloy part processing technique field, specifically relate to a kind for the treatment of solution for aluminium diecast alloy part surface treatment.
Background technology
Aluminium diecast alloy part is used widely because it has good corrosion resistance nature, and aluminium diecast alloy part needs it to be carried out surface treatment when machine-shaping, to form protective membrane.
Summary of the invention
For the technical problem existed in prior art, it is an object of the invention to provide a kind for the treatment of solution for aluminium diecast alloy part surface treatment, for achieving the above object, present invention employs following technical scheme:
For a treatment solution for aluminium diecast alloy part surface treatment, it is made up of 20 parts of sodium polyphosphates, 20 parts of terpolycyantoamino-formaldehyde resins, 10 parts of DMAC N,N' dimethyl acetamides, 5 parts of citric acids, 0.5 part of iridoid, 15 parts of ethanol and 50 parts of water.
The useful effect of the present invention shows:
1), the treatment solution that uses in surface treatment method, its formulating of recipe is reasonable, particularly with the addition of a small amount of iridoid, can significantly improve the processing efficiency for the treatment of solution.
2), the preparation method for the treatment of solution, by progressively adding and different order of addition(of ingredients), it is not only possible to improve the solubility property between each material, moreover it is possible to avoid the possibility of particle agglomeration, thus the processing efficiency making treatment solution is promoted significantly.
3), surface treatment method, operating procedure is succinct, addition processing liquid soaking step, by the preparation method of the formula of appropriate design treatment solution and treatment solution, thus realize forming one layer effective " protective film " on aluminium diecast alloy part surface, and the work-ing life of this protective film is longer, corrosion resistance nature height.
Embodiment
Below with reference to embodiment, the present invention is described in detail. But; embodiment content is only citing made for the present invention and explanation; described specific embodiment is made various amendment or supplements or adopt similar mode to substitute by affiliated those skilled in the art; as long as not deviateing the design of invention or surmounting this scope as defined in the claims, protection scope of the present invention all should be belonged to.
One, the composition for the treatment of solution
By 20 parts of sodium polyphosphates, 20 parts of terpolycyantoamino-formaldehyde resins, 10 parts of DMAC N,N' dimethyl acetamides, 5 parts of citric acids, 0.5 part of iridoid, 15 parts of ethanol and 50 parts of water.
Two, the preparation method for the treatment of solution is:
First in container, add 20 parts of sodium polyphosphates, 20 parts of terpolycyantoamino-formaldehyde resins and 15 parts of water, stir 5 minutes; Then 5 parts of citric acids are slowly added, stirring while adding, stir 5 minutes after interpolation; Then 10 parts of DMAC N,N' dimethyl acetamides and 15 parts of water are slowly added, stirring while adding, stir 5 minutes after interpolation; Then 0.5 part of iridoid is slowly added, stirring while adding, stir 5 minutes after interpolation; Finally add 15 parts of ethanol and 20 parts of water fast, stir 5 minutes.
Three, for the treatment solution of aluminium diecast alloy part surface treatment
Step 1., use that absorbent cotton is sticky to be got ethyl acetate and cleaned on aluminium diecast alloy part surface, then with dry cloth, aluminium diecast alloy part is dried, then cleans with ether, finally dry;
Step 2., aluminium diecast alloy part is put into be heated in advance 45 DEG C treatment solution soak 5 minutes;
Step 3., pull out after rinse until the pH value of wash-down water returns to neutrality with water, dry at 150 DEG C;
Step 4., spray the polytetrafluorethylenano nano protective membrane that a layer thickness is 0.5 ��m again on the surface of aluminium diecast alloy part.
