| titleOfInvention | Special polymeric dye and preparation method thereof |
| abstract | The invention relates to the technical field of electroplating, in particular to a preparation method of a special polymeric dye. The preparation raw material comprises Jianna green, wherein the dosage of the Jianna green is 15-25 g/L, and the preparation raw material also comprises 50-100 g/L of polyethylene glycol, 15-20 g/L of concentrated sulfuric acid, 10-15 g/L of sodium nitrite and 50-100 g/L of sodium salt or potassium salt. The special polymeric dye can greatly improve the thickness and compactness of the electroplated copper layer and play roles in filling, brightening and finishing a workpiece matrix. |
