Pre-plating method for ABS resin surface, plating method for ABS resin surface, and ABS resin plating product

摘要

Provided is a plating pretreatment method for a chromium- and manganese-free ABS-based resin surface, which can form a plating that adheres sufficiently to the ABS-based resin surface. An ABS resin hydrophilization treatment apparatus includes a treatment tank having a constant temperature heater provided on an outer periphery thereof, and a supply tank connected via a pipe and a pump. The treatment tank 2 and the supply tank 6 are filled with persulfate solutions S and S1 having a predetermined sulfuric acid concentration and a persulfuric acid concentration, respectively. And in the processing tank 2, the ABS resin board 7 is suspended in the up-down direction as to-be-processed ABS resin. The sulfuric acid concentration of the persulfate solutions S and S1 is 60 to 87 wt%, and the persulfate concentration of the solutions S and S1 is 2 g / L or more. Moreover, the temperature of solution S, S1 is 50-85 degreeC. [Selection] Figure 1
