The invention relates to a
vacuum evaporation patterned
metal part and a preparation method thereof.The preparation method comprises the steps that S1, a
metal base material is obtained, and the
metal base material is subjected to oil removal, washing, alkaline leaching, washing and blow-
drying to obtain a pretreated metal base material; s2, the surface of the pretreated metal base material is coated with
printing ink, pre-
drying,
exposure and developing are carried out, a patterned
printing ink layer is formed, and a developed metal part is obtained; s3, the developed metal part is placed in vacuum,
vacuum evaporation is conducted with
copper as an
evaporation source, a
vacuum evaporation copper layer is formed, the metal part obtained after vacuum
evaporation is placed in a
copper ion solution to be electroplated, and a copper-plated metal part is obtained; and S4, passivating the area, corresponding to the graphical ink, of the copper-plated metal piece to form a passive film layer, and completing preparation. According to the method, the compact copper seed layer is deposited in a vacuum
evaporation mode, then
electroplating is carried out on the seed layer, and therefore a base material-evaporation copper-
electroplating copper structure is constructed, and the
adhesive force and cohesion strength between the plating layer and the base material are enhanced.
