Abstract

The invention discloses a vehicle-mounted GPS positioning module which comprises a metal shell. The metal shell is subjected to surface treatment. The surface treatment comprises the following steps that by mass, 1-2 parts of potassium iodide, 1.8 parts of chitin, 0.7 part of nanoscale titanium dioxide, 1.5 parts of dodecyl trimethyl ammonium sulfate, 0.8 part of nickel nitrate, 1.8 parts of ammonium metavanadate and 2.3 parts of gamma-(methyl acryloyl oxygen) propyl trimethoxysilane are poured into 25 parts of deionized water and are stirred and mixed to be uniform to obtain a surface treatment working solution; 2, the surface treatment working solution is heated to 55 DEG ; 3, the metal shell is placed in the surface treatment working solution for dipping for 34 min, then taken out and dried. According to the vehicle-mounted GPS positioning module, after being subjected to surface treatment, the metal shell has the excellent waterproof performance, corrosion resistance, rust-proof performance, heat and cold resistance and weather resistance.

Description

Technical field [0001] The invention relates to a vehicle-mounted GPS positioning module. Background technique [0002] In the existing vehicle-mounted GPS positioning module, the waterproof, corrosion-resistant, rust-resistant, heat-resistant, cold-resistant, and weather-resistant performance of its metal shell needs to be improved. Summary of the invention [0003] The purpose of the present invention is to provide a vehicle-mounted GPS positioning module, the metal shell of which has undergone surface treatment and has excellent waterproof, corrosion resistance, rust resistance, heat resistance, cold resistance and weather resistance. [0004] In order to achieve the above-mentioned objective, the technical solution of the present invention is to design a vehicle-mounted GPS positioning module, which includes a metal casing that has undergone surface treatment, and the surface treatment includes the following steps: [0005] 1) Put 1 to 2 parts by mass of potassium iodide, 1.8 par...
