Abstract

The invention discloses a surface treatment technique of a CRT (cathode ray tube) lamp tube bracket stamping part, which comprises the following steps: 1) mixing 45 parts by mass of formic acid, 4 parts by mass of zinc nitrate, 4 parts by mass of sodium molybdate, 1.8 parts by mass of polyoxyethylene laurate, 3 parts by mass of sodium bifluoride, 4 parts by mass of phytic acid and 3 parts by mass of hydroxy propyl methyl cellulose, and reacting at 111 DEG C for 2 hours to obtain a metal surface treating agent; 2) mixing 8.9 parts by mass of metal surface treating agent with 93.5 parts by mass of water to obtain a surface treatment working fluid; and 3) heating the surface treatment working fluid to 53 DEG C, and immersing the metal stamping part in the surface treatment working fluid for 23 minutes. The surface treatment technique can enhance the oxidation resistance and corrosion resistance of the metal stamping part.

Description

technical field [0001] The invention relates to a surface treatment process of a metal stamping part of a CRT lamp tube support. 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 CRT lamp tube bracket, 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 kind of CRT lamp tube support metal stamping part surface treatment process, comprising the steps: [0005] 1) Take 45 parts by mass of formic acid, 4 parts by mass of zinc nitrate, 4 parts by mass of sodium molybdate, 1.8 parts by mass of polyoxyethylene laurate, 3 parts by mass of sodium bifluoride, 4 parts by mass of phytic acid, and 3 par...
