| titleOfInvention | A kind of chromium-free roughening liquid of ABS plastic and using method thereof |
| abstract | The invention discloses a chrome-free roughening solution for ABS plastics, which comprises 1-30g/L of ferrous sulfate heptahydrate, 10-100ml/L of hydrogen peroxide, 0-0.5ml/L of sulfuric acid, and 0-1.0g/L of potassium persulfate. L, citric acid monohydrate 0‑2.0g/L, EDTA 0‑2.0g/L, iron oxalate pentahydrate 0‑0.5g/L, cerium sulfate octahydrate 0‑0.05g/L, copper sulfate pentahydrate 0‑0.2 g/L, and the balance of pure water. The chrome-free roughening solution in the ABS plastic electroplating process of the present invention can effectively roughen the surface of the ABS plastic, and the surface changes from hydrophobic to hydrophilic, which improves the cohesiveness of the ABS engineering plastic surface and ensures subsequent electroplating and The bonding force of the matrix can meet the roughening requirements of ABS engineering plastics. The invention meets the requirements of environmental protection and sustainable production, can replace the existing hexavalent chromium roughening solution, and reduces environmental pollution. |
