Function additive is one kind or combinations thereof in lubricant, antioxidant, viscosity modifier.
The hot melt adhesive is hot water dissolving's type hot melt adhesive, it can be adjusted by the molecular components and structure that adjust polyvinyl alcohol
Solution temperature and solution rate can be controlled and be dissolved in 60 DEG C~95 DEG C of hot water, preferably 80 DEG C -95 DEG C.
Manufactured masking powder dispersion is simultaneously adhered to the surface of metal product by heating, heating can be baking oven heating or
The temperature of infrared heating, heating is 80 DEG C -180 DEG C, and the time is 2-5 minutes.Metal surface can be preheated, and preheating temperature is
80℃-180℃.In one embodiment, the surface of metal product is plane, and the hot melt adhesive masking direct spread of powder makes it divide at random
It dissipates in plane；In another embodiment, the surface of metal product is curved surface, and hot melt adhesive masking powder passes through electrostatic spray coating adsorption
In on curved surface.Hot melt adhesive heating, which reaches softening point, has certain viscosity, solid after cooling to be adhered to surface of metal product
It is fixed.Preferably, surface of metal product can be polished in advance, copper facing, nickel plating or combinations thereof etc. pre-process in order to follow-up
Electrophoresis.As an example, with reference to figure 1, spread after various sizes of hot melt adhesive powder mixing forms the random mixed and disorderly round spot effect of nature
Fruit.It can make hot melt adhesive powder melts and neighbouring powder by controlling the spread density and heating temperature of hot melt adhesive powder with reference to figure 2
End connects, to form the effect of strip spot.With reference to the enlarged structure schematic diagram of 3 hot melt adhesive powder of figure, by controlling powder
The condition of crushing can form the edge with corner angle, to generate the appearance for being similar to meteorite hit earth surface and being formed, tool
There is special decorative effect.
Then, to metal surface carry out an electrophoretic process, by ability cathode electrophoresis in the exposed region in metal surface (i.e. not
The region of shielded powder masking) it forms the first enamelled coating that thickness is 5-30 μm and the first enamelled coating is cured.Electrophoresis is consolidated
Content is 5-15%, pH value 4-5, voltage 45-55V, time 20-50s.Due to electrophoresis be with metal sheet as cathode into
The region of row deposition, nonconducting hot melt adhesive masking powder covering does not deposit, to realize region-type plating paint.To the first enamelled coating
Solidification can be ultra-violet curing, in 1500-2500mJ/cm after being dried 2-10 minutes at 60 DEG C -90 DEG C2It is carried out under ultraviolet light
Solidification.In addition, when covering powder using the higher hot melt adhesive of softening temperature, solidification can also use baking and curing, in 120 DEG C-
Cure 20-40 minutes at 180 DEG C.In addition, can also be realized by anodic electrophoresis, not in this to go forth.
After electrophoresis, masking powder is removed from metal surface and cleans metal surface.In one embodiment, by metal
Surface is immersed in organic solvent to be melted until powder swelling will be covered, and the masking powder is removed by wiping.
Organic solvent be acetone, cyclohexanone, acetic acid, ethyl acetate, butanone, tetrahydrofuran, dichloromethane, trichloroethanes,
Ethyl propionate, butyl acetate, hexamethylene, n,N-dimethylacetamide, isopropanol, butanol etc. are carried out by the similar principle that mixes
Swelling dissolving is removed.Since hot melt adhesive is thermoplastic material, and electrophoretic paint is typically thermosets, is not swollen substantially,
Thus on electrophoretic paint without influence.In another embodiment, masking powder is hot water dissolving's type hot melt adhesive, and masking powder is soaked in heat
Make it dissolve and clean removing in water, the temperature of the hot water is 40 DEG C~95 DEG C, and soaking time is 10min~60min, also can be
The organic solvents such as appropriate dimethyl sulfoxide (DMSO), glycerine are added in water and cleaning process is accelerated by stirring or ultrasonic wave.It is above-mentioned
Method can remove rapidly hot melt adhesive masking powder, and cleaning process is simple, non-corrosive substance, make without destruction to preceding road electrophoretic paint
With, it is ensured that the performance of electrophoretic paint.Wherein, in water soluble type hot melt adhesive, polyvinyl alcohol is Biodegradable polymer material,
It is 46 days degradable 75%, non-hazardous to environment under bacterium and enzyme effect.
Then, secondary electrophoretic process is carried out to metal surface, powder overlay area is covered (at this time in original by ability cathode electrophoresis
The subregion metal covering is exposed) it forms second enamelled coating different with the first enamelled coating color and the second enamelled coating is cured,
In the thickness of second enamelled coating be 5-30 μm, the solid content of the secondary electrophoresis is 5-15%, pH value 4-5, voltage 35-45V,
Time is 20-50s, and solidification is similar with the solidification of the first enamelled coating.First enamelled coating and the second enamelled coating color are different, for example, the
One enamelled coating is black modelled after an antique, and the second enamelled coating is bronze；Alternatively, the first enamelled coating is brown, the second enamelled coating is light yellow, thus
Form dot pattern corresponding with masking mealy structure.
Product obtained by the method for the present invention is tested, the results are shown in Table 1：
| Test event | Test condition | Test result | Traditional standard |
