Abstract

The invention discloses a warning signboard. A metal plate main body is subjected to passivation treatment. The passivation treatment comprises the following steps: 1) putting 1 to 2 parts by weight of sodium citrate, 4.2 parts by weight of malonic acid, 0.9 part by weight of triazole, 0.7 part by weight of boron anhydrous and 1.1 parts by weight of nano-silica into 30 parts by weight of deionized water in sequence, and stirring uniformly; 2) adding 1.5 parts by weight of sodium pyrophosphate, 0.9 part by weight of n-butyl-naphthalene sulfonate, 1.4 parts by weight of triethylamine, 1.6 parts by weight of dioctyl sulfosuccinate sodium salt and 5.2 parts by weight of butyl acrylate in sequence, and stirring continually till the materials are mixed fully and uniformly to obtain passivation treatment liquid; 3) putting the metal plate main body into the passivation treatment liquid to perform passivation treatment at the temperature of 41 DEG C for 39 seconds, taking the metal plate main body out, cleaning the metal plate main body with pure water, and drying. The metal plate main body is subjected to the passivation treatment, so that the warning signboard has high performance and high surface finish.

Description

technical field [0001] The invention relates to a warning sign board. Background technique [0002] The existing warning signs include a metal plate main body, but the anti-rust, 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 warning signs, the main body of the metal plate is passivated to form a uniform passivation protective film on the metal surface, which has excellent rust resistance, 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 warning sign, which includes a metal plate main body, and the metal plate main body has undergone passivation treatment, and t...
