Change.In addition, solidification is baking and curing, solidifies 20- at 120 DEG C -180 DEG C when using softening temperature higher hot-melt adhesive film
40 minutes.In addition, can also be realized by anodic electrophoresis, not in this to go forth.
After electrophoresis, nethike embrane is removed from metal surface and cleans metal surface.In one embodiment, by metal surface
Nethike embrane be swollen in organic solvent dissolve and remove.Organic solvent is acetone, cyclohexanone, acetic acid, ethyl acetate, butanone, four
Hydrogen furans, methylene chloride, trichloroethanes, ethyl propionate, butyl acetate, hexamethylene, n,N-dimethylacetamide, isopropanol, fourth
Alcohol etc. carries out swelling dissolution by the similar principle that mixes and removes.Hot melt adhesive is thermoplastic material, and electrophoretic paint passes through hot setting
Or ultraviolet light solidification after be thermosetting material, organic solvent effect under, Thermoplastic hot melt glue is swollen, be easy removing
Fall, and thermosetting property electrophoretic paint is not swollen substantially then, will not be had an impact to electrophoretic paint.In another embodiment, nethike embrane
It is hot water dissolving's type hot melt adhesive, nethike embrane is soaked in hot water and makes it dissolve and clean removal, the temperature of the hot water is 60 DEG C~
95 DEG C, soaking time is 10min~60min, and preferred temperature is 80 DEG C -95 DEG C.By adding appropriate two into the hot water
Methyl sulfoxide or glycerol, stirring hot water or vibration of ultrasonic wave hot water accelerate the cleaning of hot water dissolving's type hot melt adhesive shielding film
Journey.The above method can remove rapidly hot-melt adhesive film, and cleaning process is simple, non-corrosive substance, to preceding road electrophoretic paint without destruction
Effect, it is ensured that the performance of electrophoretic paint.Wherein, in water soluble type hot melt adhesive, polyvinyl alcohol is Biodegradable high-molecular material
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, by ability cathode electrophoresis in former nethike embrane overlay area (portion at this time
Subregion metal covering is exposed) it deposits second paint layer different with the first paint layer color and the second paint layer is solidified, wherein should
Second paint layer with a thickness of 5-30 μm, the solid content of the secondary electrophoresis is 5-15%, pH value 4-5, voltage 35-45V, time
For 20-50s, solidify similar with the solidification of the first paint layer.First paint layer and the second paint layer color are different, for example, the first paint
Layer is black modelled after an antique, and the second paint layer is bronze；Alternatively, the first paint layer is brown, the second paint layer is light yellow, to be formed
Corresponding with web structure cross-hatched pattern.
