Title:

METHOD FOR TREATING PLASTIC SURFACE

Document Type and Number:

WIPO Patent Application WO/2018/083884

Kind Code:

A1

Abstract:

A treatment device 1 has a treatment tank 2 on the outside of which a constant temperature heater 3 is provided and a supply tank 6 connected via a pipe 4 and a pump 5. Persulfuric acid salt solutions S and S1 of prescribed sulfuric acid concentrations and persulfuric acid concentrations are respectively filled in the treatment tank 2 and the supply tank 6. In the treatment tank 2, a plastic sheet 7 is suspended vertically as plastic to be treated. The sulfuric acid concentrations of the persulfuric acid salt solutions S and S1 are 50-92 wt%. The persulfuric acid concentrations of the solutions S and S1 after dissolving the persulfuric acid salt are 3-20 g/L. With the method for treating a Cr-free plastic surface that uses said treatment device 1, it is possible to form metal plating that adheres well to the plastic surface.
