Description
Technical field
The present invention relates to a kind of spring electrophoresis process.
Background technology
In order to prevent that the spring burn into from getting rusty, the most frequently used method is to the spring japanning at present.And the general mode of spraying that adopts of tradition is given the spring japanning.Adopt the technology of spraying to give the spring japanning, easily cause spring inner ring japanning inequality, problem such as easily fade behind the spring japanning, simultaneously, spraying coating process extremely wastes raw material, and utilization ratio of raw materials is extremely low, also causes great environmental pollution.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of spring electrophoresis process that adopts electrophoretic mode to give the spring japanning.
The present invention adopts following technical scheme: a kind of spring electrophoresis process, and described electrophoresis process may further comprise the steps:
1) spring is placed is fixed on the electrophoresis hanger;
2) the electrophoresis hanger being immersed in fully pH value is in the 5.8-6.2 electrophoresis groove liquid, under 30-34 ℃, electroplates 15-60s with the 1400-1800S/m specific conductivity, the electrophoresis hanger is taken out again, and the component of described electrophoresis groove liquid and mass fraction are:
Mill base 2-4 part,
Tank liquor solubility promoter 0.4-0.7 part,
Lacquer liquid neutralizing agent 0.4-0.7 part,
Ability cathode electrophoresis paint emulsion 16-24 part,
100 parts of deionized waters;
3) will be through step 2) the electrophoretic electrophoresis hanger that is fixed with spring takes out and dries naturally;
4) will put into baking vessel through the electrophoresis hanger that the step 3) air dried is fixed with spring, 150-170 ℃ of baking 20-40 minute;
5) the electrophoresis hanger naturally cooling that is fixed with spring after will toasting, and spring taken off from the electrophoresis hanger.
Among the present invention, described ability cathode electrophoresis paint emulsion is the commercially available prod, purchases the gloomy coating of the great power company limited in Shanghai
Company, the trade mark is HB-3500.
Described mill base is red mill base, blue mill base, yellow mill base, coffee-like mill base or green mill base etc.According to the needs of concrete production, select suitable mill base.
Among the present invention, the mill base content in the electrophoresis groove liquid has very big influence to electrophoretic painting.When mill base content low excessively, the electrophoresis groove liquid poor stability, the paint film deposition is low, permeability ratio is low, and the electrolysis aggravation of water and the generation of a large amount of gases will influences the formation rete on the electrode, defectives such as pin hole is coarse occur.When the increase of mill base content, electrodeposition weight increases thereupon, and throwing power increases.When tank liquor viscosity increases excessively, the speed of mill base micelle swimming is slack-off, and the deposition of filming is too much, and rete is blocked up, and electric osmose is poor, the paint film coarse poor adhesive force of loosen, and the while has also increased the loss of taking mill base out of when workpiece goes out groove.Therefore in the electrophoretic painting, mill base content is controlled within certain processing condition scope.
Tank liquor solubility promoter of the present invention is ethanol or glacial acetic acid.Electrophoretic paint except adding a large amount of deionized waters as the solvent, also must add an amount of tank liquor solubility promoter when the preparation electrophoresis groove liquid, in order to improve the water-soluble of mill base, regulate the viscosity of electrophoresis groove liquid, and then increases the stability of electrophoresis groove liquid.The tank liquor solubility promoter also will influence the electrodeposition weight of mill base simultaneously, improve the levelling property of mill base at workpiece surface, increase the glossiness and the planeness of rete.Tank liquor solubility promoter in the electrophoresis groove liquid must be suitably, if content is low excessively, the effect of tank liquor solubility promoter is not obvious; If too high levels also can cause the rete attenuation, throwing power reduces, and the pulsed electrical rheology is big, and rete easily causes phenomenons such as pin hole shrinkage cavity.
Described lacquer liquid neutralizing agent is the glacial acetic acid aqueous solution of concentration 20-30%, when the pH value of tank liquor is bigger than normal, adds the pH value that neutralizing agent is adjusted tank liquor.
The pH value of electrophoresis groove liquid of the present invention is preferably 6.0.The pH value of electrophoresis groove liquid has a significant impact the electrophoretic painting tool.Mill base is a colloidal dispersion system, so the pH value of electrophoresis groove liquid directly influences the double electrical layers of mill base micelle, thereby influence the stability of electrophoresis groove liquid, the variation significantly of pH value will cause the sedimentation of mill base, electrophoretic painting can't normally be carried out, because charged ability cathode electrophoresis paints emulsion generation electrolytic reaction, the pH value of electrophoresis groove liquid is constantly changed in the spring electrophoresis process, promptly influence the stability of electrophoresis groove liquid, also changed the specific conductivity of electrophoresis groove liquid.Therefore in the electrophoretic painting process, need often to adjust the pH value of electrophoresis groove liquid, it is strict controlled within the 5.8-6.2 scope, be preferably 6.0.The pH value of electrophoresis groove liquid can be added lacquer liquid neutralizing agent by adjusting and control.
The specific conductivity of electrophoresis groove liquid of the present invention is preferably 1600 S/m.The specific conductivity of electrophoresis groove liquid directly influences the electrochemical properties of electrophoresis groove liquid, promptly influences the dual band electro layer structure of charged colloidal particles in the mill base, thereby electrophoretic painting is impacted.If specific conductivity is excessive, then swimming speed is excessive, and the pulsed electrical rheology is big, the electrolytic reaction aggravation, and paint film is loose to be prone to phenomenon such as pin hole, and throwing power reduces, so the specific conductivity that needs strict control electrophoresis groove liquid in 1400-1800 S/m, is preferably 1600 S/m.
The electrophoresis hanger of spring electrophoresis process of the present invention, it comprises support body, support body is provided with the above lanyard of two rows, hangs on every row's lanyard and fixes two with upper spring.Adopt such device, can on the support body of spring electrophoresis hanger, once hang fixing a plurality of springs,, thereby improve spring electrophoresis japanning efficient then to electrophoresis japanning of these springs.
Adopt spring electrophoresis process of the present invention, spring inner ring japanning is even, be difficult for fading behind the spring japanning, and electrophoresis groove liquid utilization ratio height, the thicknesses of layers on spring surface is even, surfacing, glossy degree.Simultaneously, the electrophoresis hanger of the present invention's employing can once be given a plurality of spring electrophoresis japannings, japanning efficient height.
