Abstract

The invention discloses a surface treatment process for shell metal stamping parts. The surface treatment process comprises the steps of 1, mixing 12.3 parts of benzoic acid, 1-2 parts of N-methyl pyrrolidone, 1.3 parts of phosphoric acid, 1.8 parts of phenylcarbinol, 2.1 parts of p-tert-butyl benzoic acid, 2.3 parts of fatty alcohol-polyoxyethylene ether sodium sulfate and 1.7 parts of 2,6-di-tert-butylphosphine-alpha-dimethylamino phenol by weight at 75 DEG C for 1.5 hours for obtaining metal surface treatment agents; 2, obtaining surface treatment work solutions through 23 parts of the metal surface treatment agents and 33 parts of water by weight; 3, warming the surface treatment work solutions to 51.5 DEG C, and placing the metal stamping parts into the surface treatment work solutions for 42 minutes. According to the invention, the oxidation resistance and the corrosion resistance of the metal stamping parts can be improved.
