Abstract
The invention relates to the technical field of die-cast aluminum alloy part processing, in particular to a preparing method of treating fluid used for treating the surfaces of die-cast aluminum alloy parts. Firstly, 20 parts of sodium polyphosphate, 20 parts of melamine-formaldehyde resin and 15 parts of water are added into a container; then 5 parts of citric acid is slowly added and stirred and is continuously stirred after being added; then 10 parts of N,N-dimethylacetamide and 15 parts of water are slowly added and stirred and is continuously stirred for 5 minutes after being added; then 0.5 part of iridoid is slowly added and stirred and is continuously stirred for 5 minutes after being added; and finally, 15 parts of ethyl alcohol and 20 parts of water are quickly added and stirred for 5 minutes. According to the preparing method of the treating fluid, the dissolving property between all materials is improved by adding the materials step by step and through different material adding sequences, and the possibility of particle aggregation is avoided. Thus, the treating efficiency of the treating fluid is obviously improved.
Description
Technical field
The present invention relates to aluminium diecast alloy part processing technique field, specifically relate to a kind of preparation method for aluminium diecast alloy part surface-treated treatment solution.
Background technology
Aluminium diecast alloy part is used widely because it has good corrosion resistance nature, and aluminium diecast alloy part needs when machine-shaping to carry out surface treatment to it, to form protective membrane.
Summary of the invention
For the technical problem existed in prior art, the object of the present invention is to provide a kind of preparation method for aluminium diecast alloy part surface-treated treatment solution, for achieving the above object, present invention employs following technical scheme:
For a preparation method for aluminium diecast alloy part surface-treated treatment solution, in container, first add 20 parts of sodium polyphosphates, 20 parts of terpolycyantoamino-formaldehyde resins and 15 parts of water, stir 5 minutes; Then slowly add 5 parts of citric acids, limit edged stirs, and stirs 5 minutes after interpolation; Then slowly add 10 parts of N,N-dimethylacetamide and 15 parts of water, limit edged stirs, and stirs 5 minutes after interpolation; Then slowly add 0.5 part of iridoid, limit edged stirs, and stirs 5 minutes after interpolation; Finally add 15 parts of ethanol and 20 parts of water fast, stir 5 minutes.
Beneficial 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), the solubility property between each material can not only be improved, the possibility of particle agglomeration can also be avoided, thus the processing efficiency for the treatment of solution is promoted significantly.
3), surface treatment method, operating procedure is succinct, addition processing liquid soaking step, by the formula of appropriate design treatment solution and the preparation method for the treatment of solution, thus realize forming one deck effective " protective film " on aluminium diecast alloy part surface, and the work-ing life of this protective film is longer, corrosion resistance nature is high.
