Traffic sign

Abstract

The invention discloses a traffic sign of which a metal plate main body is subjected to passivating treatment. The passivating treatment comprises the following steps: 1) sequentially adding 1-2 parts by weight of phosphate, 4.1 parts by weight of phosphorus tungsten heteropoly acid, 5.1 parts by weight of fluorozirconic acid, 0.9 part by weight of sodium benzoate and 1.3 parts by weight of hydrogen peroxide into 30 parts by weight of deionized water, and stirring uniformly; 2) sequentially adding 3.6 parts by weight of hexyl decanol, 1.6 parts by weight of alkyltrimethylammonium methylsulfate, 1.8 parts by weight of 1-hydroxybenztriazole, 2.5 parts by weight of alkylphenol polyoxyethylene and 4.1 parts by weight of dipropanediol, continuing stirring and sufficiently mixing uniformly to obtain a passivating treatment solution; and 3) putting the metal plate main body in the passivating treatment solution, carrying out passivating treatment at 37 DEG C for 43 seconds, taking out, cleaning with pure water, and drying. The metal plate main body of the traffic sign is subjected to passivating treatment, so the traffic sign has favorable properties and favorable surface smoothness.

Description

technical field [0001] The invention relates to a traffic sign board. Background technique [0002] The existing traffic signs include a metal plate main body, but the antirust, abrasion resistance, corrosion resistance, heat resistance, cold resistance, and weather resistance of the metal plate main body need to be improved, and the surface finish is not ideal. Contents of the invention [0003] The object of the present invention is to provide a kind of traffic sign board, its metal plate main body passes passivation treatment, forms uniform passivation protection film on the metal surface, has excellent antirust, abrasion resistance, corrosion resistance, heat resistance, cold resistance, Weather resistance, and good surface finish. [0004] In order to achieve the above object, the technical solution of the present invention is to design a traffic sign, which includes a metal plate main body, which is passivated, and the passivated treatment includes the following ste...
