Description
Technical field
The present invention relates to Phosphating Solution technical field, in particular, it is related to a kind of fast bonderizing liquor and preparation method thereof.
Background technology
With developing rapidly for metal-processing industry, phosphating process is especially painted in Treatment of Metal Surface（Or spray painting）Before
The application of the aspects such as treatment is increasingly extensive.Presently used Phosphating Solution is generally medium and high temperature Phosphating Solution（55 DEG C -95 DEG C of temperature in use）,
Phosphating coat obtained in this kind of Phosphating Solution, thick with crystallizing, film layer is thicker, and phosphating time is long, and phosphating equipment investment is big, energy consumption
The high, unfavorable factor such as acid mist is big, stability of solution is poor, sediment is more, adjustment is cumbersome, environmental protection pressure is big.
Chinese patent CN102605364 discloses a kind of middle overcast slag low emission phosphorization of thick film liquid of temperature and its method for bonderizing,
The component of the Phosphating Solution is：Mazhev salt 3~5%, zinc nitrate 9~12%, manganese nitrate 3~5%, ammonium molybdate 0~
0.01%, sodium chlorate 0~0.02%, citric acid 0.01~0.03%, ethylenediamine tetra-acetic acid 0.01~0.03%, surplus
It is water, by weight.Although the patent Phosphating Solution produces few sediment in use, its free acidity is extremely low,
The shortcomings of film is difficult, and phosphating time is long is caused in phosphatization.
The content of the invention
An object of the present invention is to overcome the deficiencies in the prior art, there is provided a kind of fast bonderizing liquor, this Phosphating Solution phosphorus
The change time is short, substantially increases operating efficiency, and temperature in use is low, reduces energy consumption, and without processing sediment.
The second object of the present invention is the preparation method for providing above-mentioned fast bonderizing liquor.
To achieve the above object, the technical solution adopted by the present invention is as follows：
A kind of fast bonderizing liquor, by percentage to the quality, is made up of following raw material：
Phosphatase 11 5-20%, zinc oxide 6-10%, zinc nitrate 20-25%, m-nitrobenzene sodium sulfonate 1-5%, citric acid 0.5-2%, second two
Amine tetraacethyl（EDTA）1-4%, balance of water.
Currently preferred technical scheme is：A kind of fast bonderizing liquor, by percentage to the quality, is made up of following raw material：
Phosphatase 11 5-18%, zinc oxide 7-9%, zinc nitrate 20-22%, m-nitrobenzene sodium sulfonate 1-2%, citric acid 0.5-1%, ethylenediamine
Tetraacethyl（EDTA）1-2%, balance of water.
Technical scheme of the invention preferred is：
Phosphatase 11 5%, zinc oxide 9%, zinc nitrate 22%, m-nitrobenzene sodium sulfonate 1%, citric acid 1%, ethylenediamine tetra-acetic acid（EDTA）
1%, water 51%.
A kind of fast bonderizing liquor, by percentage to the quality, is made up of following raw material：
The preparation method of fast bonderizing liquor of the present invention in turn includes the following steps：
（1）Phosphoric acid is added in a kettle., is opened reactor and is stirred；
（2）The water of the total consumption 40%-60% of water needed for being added toward reactor；
（3）Zinc oxide is added toward reactor；
（4）Reaction is completely and after solution clarification toward adding remaining water in reactor；
（5）Zinc nitrate is added toward reactor, stirs and make solution to clarify；
（6）M-nitrobenzene sodium sulfonate is added toward reactor, stirs and make solution to clarify；
（7）Finally toward addition citric acid, EDTA in reactor, stir and solution clarification.
Main operational principle of the invention is as follows：
Steel and iron parts immerse Phosphating Solution（By Zn (H2PO4）2The acid dilute aqueous solution of composition, pH value is 1-3）In, the generation of phosphating coat
Reaction is as follows：
3Zn(H2PO4）2 =Zn3(PO4）2↓+4H3PO4
Iron and steel parts are steel and alloy, under phosphatizing, Fe and FeC3Countless galvanic cells are formed, in anode region, iron starts molten
It is Fe to solve2+, while ejected electron.
Fe+2H3PO4 =Fe (H2PO4）2+H2↑
Fe =Fe2+ +2e-
Fe in solution near surface of steel workpiece2+It is continuously increased, works as Fe2+With HPO4 2-, PO4 3-Concentration is more than phosphatic
During solubility product, precipitation is produced, phosphating coat is formed in workpiece surface：
Fe(H2PO4）2= FeHPO4↓+ H3PO4
Fe+ Fe(H2PO4）2= 2FeHPO4↓+ H2↑
3FeHPO4= Fe3(PO4）2↓+ H3PO4
Fe+ 2FeHPO4 =Fe3(PO4）2↓+H2↑
Cathodic region releases substantial amounts of hydrogen：
2H+ +2e- =H2↑
O2 + 2H20 + 4e- =4OH-
Net reaction：
3Zn(H2PO4）2= Zn3(PO4）2↓+4H3PO4
2Fe+3Zn(H2PO4）2= Zn3(PO4）2↓+2FeHPO4↓+2H3PO4+ 2H2↑
Wherein Zn3(PO4）2、FeHPO4It is the composition of phosphating coat；Formula intermediate nitro benzene sulfonic acid sodium salt adds accelerator in, and additional
Accelerator should just use when with groove, and accelerator can shorten the time of phosphating coat formation；Citric acid plays refinement phosphatization in formula
Crystallization, the effect for reducing thickness.Ethylenediamine tetra-acetic acid is complexing agent in formula, reduces slagging scorification amount during phosphorating treatment.
The application method of Phosphating Solution of the present invention is（To prepare lm3As a example by）：The water of 1/2 volume, plus 50-100 are contained in groove
Kilogram Phosphating Solution, adds water to cumulative volume lm3（3-6 kilograms of Phosphating Solution added promoter is just added using preceding）Stir, survey
Examination total acidity is between 18-30pt and free acidity 0.6-1.5pt between.
Bath maintenance：In processing procedure, total acidity is less than at 18 points to workpiece, and free acidity should add one when being less than at 0.6
Quantitative Phosphating Solution, per m340kg General Acidity in Phosphating Solution is added to improve 2 points or so in tank liquor, free acidity improves 0.2 point or so,
Pay special attention to, added promoter is decomposed reaction in use, according to the situation of phosphating coat, should be continuously added dropwise additional
Accelerator, it is ensured that tank liquor is steady in a long-term.
The phosphating coat cupric sulphate dropping test time of Phosphating Solution of the present invention up to 30 seconds, the neutral salt spray test time up to 4 hours,
Paint film adhesion meets country and professional standard up to 0 grade；Phosphating time of the present invention is short simultaneously, substantially increases operating efficiency, makes
It is low with temperature.And phosphating dregs are not produced substantially, cleaning cycle is substantially prolongs, and fixed-end forces expense are reduced, without disappearing
Power consumption source.
