Title:
PLATING PRETREATMENT METHOD FOR ABS RESIN SURFACE, PLATING TREATMENT METHOD FOR ABS RESIN SURFACE, AND ABS RESIN PLATED PRODUCT
Document Type and Number:
WIPO Patent Application WO/2019/045047
Kind Code:
A1
Abstract:
A treatment device 1 has: a treatment tank 2 provided with a constant temperature heater 3 on the outer periphery; an electrolytic cell 6 continuing from a pipe 4 provided with a circulation pump 5; and a pipe 7 for supply to the treatment tank 2 from the electrolytic cell 6. Within the electrolytic cell 6 are provided a positive electrode 6A and a negative electrode 6B formed from diamond electrodes and a bipolar electrode 6C disposed between the two. The treatment tank 2 and the electrolytic cell 6 are filled with a prescribed concentration of sulfuric acid. The treatment device is configured such that a persulfate solution S such as peroxydisulfuric acid is generated by electrolysis of the sulfuric acid by making a prescribed current flow from a direct current power supply unit to the positive electrode 6A and the negative electrode 6B, and this persulfate solution S can be supplied to the treatment tank 2 via the pipe 7. A plating pretreatment method for Cr and Mn-free ABS resin surfaces that can form plating sufficiently adhering to an ABS resin surface can be applied to this treatment device 1.
