Method for treating surface of plastic |
| abstract |
Provided is a Cr-free plastic surface treatment method which can provide a plating film sufficiently adhered to a plastic surface. The plastic surface treatment method includes treating plastic with a solution obtained by electrolyzing sulfuric acid. It is preferable that the sulfuric acid concentration of the sulfuric acid solution is 50 to 92 wt %, the persulfuric acid concentration is not less than 3 g/L, and the treatment temperature is not lower than 80° C., for example, 80 to 140° C., particularly 100 to 130° C. By immersing plastic in this sulfuric acid solution for 1 minute to 10 minutes, hydrophilic functional groups are exposed on the surface of the plastic. |
