The method is simple and practicable. PEO resin makes PC/ABS surface have the property of hydrophilicity, which makes the etching solution easier to wet the surface when under etching, so that the etching becomes much easier. The binding force of hydrophilic group on the surface of PEO to the metal is strong. The binding force of PC/ABS alloy material is improved due to the combination between the chemical bond and physical force.

An easily-electroplated electroplating PC/ABS alloy material and a method for preparing same. The alloy material comprises the following components in parts by weight: 30-70 parts of a PC resin, 15-65 parts of an ABS resin, 5-10 parts of a PEO resin, 0.1-1 part of an antioxidant, and 0.1-1 part of a lubricant. During the preparation process, adding the PC resin, the ABS resin, the PEO resin, the antioxidant and the lubricant into a mixing agitator for mixing; and blending and granulating the resulting mixture through a twin-screw extruder to produce an easily-electroplated electroplating PC/ABS alloy material. The method is simple and feasible; the PC/ABS surface is hydrophilic due to the existence of the PEO resin, and the coarsening liquid infiltrates the surface more easily during the processes of electroplating and coarsening, and as a result the coarsening is easier; the binding force between the hydrophilic groups of a PEO surface and the metal is high; besides the physical combination, a chemical bond combination also exists, and by means of these two aspects, the electroplating effect of the PC/ABS alloy material is enhanced.
