Rust is a mixture of oxides and hydroxides formed on the surface of metals by the action of oxygen and water, and is red, while patina is green, and rust of aluminum and zinc is called white rust. The machinery is difficult to operate and store without contacting with oxygen, moisture or other corrosive media in the air, and the substances are corroded electrochemically on the metal surface to generate rust, and the rust is prevented so as to prevent the substances from contacting with the metal. Therefore, the research of the antirust liquid plays an important role in protecting the metal workpieces. Most of metal water-based antirust liquid used in the current market contains sodium nitrite, nitrite-type water-based antirust liquid has the obvious advantages of low price, good effect, convenient use, easy removal and the like, and is widely used, but people prove that nitrite can be converted into carcinogen to strictly limit the use and discharge of the nitrite, and due to the reasons of environmental protection and the like, people have been dedicated to the research of non-nitrite environment-friendly water-based antirust agent for many years and have made great progress, the traditional water-based antirust treatment is to dissolve sodium nitrite, bichromate and the like into water according to certain concentration to form water-based antirust liquid, and the metal water-based antirust liquid is characterized by simple operation and is suitable for short-term antirust in metal processing procedures, and the antirust period is about half a year; the antirust agent has high toxicity to operators, serious environmental pollution and short antirust time, and can not meet the existing production requirements. Although the rust preventive oil has good rust preventive property, the cost is high, and the post treatment of the steel products is difficult. In recent years, the research on environment-friendly water-based antirust agents is widely concerned at home and abroad, and particularly the development of long-acting water-based antirust agents becomes a trend.
