Abstract

The invention discloses a surface treatment process for a radiator shell metal stamping piece. The surface treatment process comprises the following steps: 1) mixing 15 parts by mass of benzoic acid, 8 parts by mass of polyoxyethylene sorbitan fatty acid ester, 2 parts by mass of sodium molybdate, 4 parts by mass of nickel nitrate, 4 parts by mass of sodium hydrogenfluoride, 2 parts by mass of phytic acid and 3.6 parts by mass of hydroxypropyl methyl cellulose, and reacting for 3.5 hours at 110 DEG C to obtain a metal surface treatment agent; 2) mixing 13 parts by mass of metal surface treatment agent and 96 parts by mass of water to obtain a surface treatment working solution; and 3) heating the surface treatment working solution to 50 DEG C, and putting the metal stamping piece into the surface treatment working solution for 25 minutes. The surface treatment process for the radiator shell metal stamping piece can improve the oxidation resistance and corrosion resistance of the metal stamping piece.

Description

technical field [0001] The invention relates to a surface treatment process for metal stamping parts of radiator shells. Background technique [0002] The anti-oxidation and anti-corrosion capabilities of existing metal stamping parts need to be improved. Contents of the invention [0003] The purpose of the present invention is to provide a surface treatment process for the metal stamping part of the radiator shell, so as to improve the anti-oxidation and anti-corrosion capabilities of the metal stamping part. [0004] In order to achieve the above object, the technical solution of the present invention is to design a surface treatment process for the metal stamping part of the radiator shell, including the following steps: [0005] 1) Take 15 parts by mass of benzoic acid, 8 parts by mass of polyoxyethylene sorbitan fatty acid ester, 2 parts by mass of sodium molybdate, 4 parts by mass of nickel nitrate, 4 parts by mass of sodium hydrogen fluoride, 2 parts by mass of ph...
