Description
Technical Field
The invention relates to the technical field of phosphating agents, in particular to a zinc-series low-slag phosphating agent and a preparation method thereof.
Background
The phosphating treatment of the workpiece is required when coating automobiles, household appliances and the like, the binding force of the metal and a paint film is poor, and the phosphating treatment of the metal surface is required before metal spraying in order to provide the adhesive force of the subsequent paint film. The phosphating treatment is a traditional surface treatment method, and is a process of chemically treating a metal plate in an acidic phosphate solution to form a layer of conversion film; the microporous structure of the phosphating film has a large surface area, and can enhance the adhesive force with a paint film, thereby improving the comprehensive performance of metal, so that the quality of the phosphating film is of great importance. The most outstanding problem of the existing metal phosphating treatment in the production line is that the whole line heating consumes energy, and the phenomena of increase of phosphating sediments, porous dull and rough phosphating film layers and the like occur to cause the waste of phosphating agents.
Disclosure of Invention
In view of the above, the present invention aims to solve the above problems and provide a zinc-based low-slag phosphating agent and a preparation method thereof, which have the advantages of low energy consumption, less slag deposition, convenient maintenance and capability of meeting the requirements of various coating performances.
In order to achieve the purpose, the invention provides the following technical scheme: a zinc series low slag phosphating agent takes water as a solvent, and comprises a film forming substance, an acidity regulator, a first promoter, a second promoter, a third promoter, a chelating agent and a complexing agent, wherein the weight ratio of the film forming substance to the third promoter to the chelating agent is as follows: 21-40% of film forming material, 10-20% of acidity regulator, 0.1-0.5% of first promoter, 0.001-0.01% of second promoter, 0.3-0.8% of third promoter, 0.5-1.5% of chelating agent, 1-5% of complexing agent and the balance of water.
The film forming material comprises 6-15% of zinc oxide and 15-25% of phosphoric acid, an acidity regulator is nitric acid, a first promoter is nickel nitrate, a second promoter is copper nitrate, a third promoter is sodium m-nitrobenzenesulfonate, a chelating agent is trisodium citrate, and a complexing agent is ethylenediamine tetraacetic acid.
Further, the water is pure water.
S1, sequentially adding water, zinc oxide, phosphoric acid and nitric acid under stirring, and stirring for 20-30 minutes until the zinc oxide is completely dissolved and the solution is transparent;
adding nickel nitrate and copper nitrate into the solutions of S2 and S1, and stirring for about 5-10 minutes until the solutions are transparent;
heating the solution of S3 and S2, keeping the temperature at 50-70 ℃, adding sodium m-nitrobenzenesulfonate, and stirring for about 20-40 minutes until the solution is transparent and is completely dissolved;
s4, standing the solution of S3 for cooling, adding trisodium citrate and ethylenediamine tetraacetic acid when the temperature is lower than 40 ℃, stirring for 20-30 minutes until the trisodium citrate and the ethylenediamine tetraacetic acid are completely dissolved, and feeding the sample after the solution is uniform and transparent for detection and packaging. Complete dissolution here means that the solid solute cannot be seen by the naked eye of a person.
Compared with the prior art, the invention has the beneficial effects that:
the functions of zinc oxide, phosphoric acid and nitric acid are as follows: the phosphating solution mainly provides zinc ions and is a main component for forming a phosphating film. The zinc oxide reacts with phosphoric acid to prepare zinc phosphate which can be used for corrosion prevention and rust prevention of metal surfaces, namely, a zinc-iron-phosphate coating is formed on the metal surfaces.
The reaction equation of the phosphating solution is as follows: phosphoric acid + zinc oxide → zinc dihydrogen phosphate + water
Nitric acid + zinc oxide → zinc nitrate + water
Function of nickel nitrate: the nickel nitrate has the functions of providing nickel ions, refining the film layer and increasing the antirust effect of the phosphating film in the phosphating solution. The involucra generated by the reaction is promoted to be more uniform and compact, and the matching of the phosphating film and the subsequent electrophoresis is more perfect.
Copper nitrate plays an accelerating role in the phosphating solution, the generation speed of a phosphating film can be improved, but the addition amount is extremely low, otherwise, copper is separated out if the addition amount is too large, and the adhesion and the corrosion resistance of the phosphating film are seriously influenced. If copper nitrate is not added, the speed of the phosphating solution is influenced, particularly the phosphating solution at normal temperature.
The function of the sodium m-nitrobenzenesulfonate in the phosphating solution is as follows: sodium m-nitrobenzenesulfonate is also known as sodium 3-nitrobenzenesulfonate. The organic promoter is one of the best organic promoters in aromatic nitro compounds, is used for zinc series phosphorization, has good acceleration effect (not less than sodium nitrite in terms of acceleration), has fast crystal nucleus growth and good film forming property, and can play roles in reducing film weight and refining crystallization. The concentration of the sodium m-nitrobenzenesulfonate is preferably 0.35-1.5 g/L. Too high a concentration, coarse crystals, floating grayish, pale (yellowish) color.
The mechanism of action of the sodium m-nitrobenzenesulfonate is to increase the initial corrosion rate and inhibit the anode reaction by blocking the anode region. Sodium m-nitrobenzenesulfonate is mostly used for phosphating at medium and normal temperatures.
The use of sodium m-nitrobenzenesulfonate has the advantages that: wide control range, good stability and no need of frequent replenishment.
The function of sodium citrate in the phosphating solution is as follows: the addition of sodium citrate is helpful for increasing the thickness of the phosphating film, and the phosphating film is crystallized, continuously, completely, uniformly and compactly in the phosphating solution at normal temperature and low temperature. In addition, sodium citrate also has metal ion complexing ability. Sodium citrate para Ca2+、Mg2+The plasma metal ions have good complexing ability to other metal ions, such as Fe2+The plasma also has good complexing ability.
The function of the ethylene diamine tetraacetic acid in the phosphating solution is as follows: can form stable complex with iron ion, and can prevent generation of precipitate.
The invention has low energy consumption, less sediment and convenient maintenance in the using process, and the quality of the phosphating film formed after product treatment is stable, thereby improving the comprehensive performance of metal.
