Background
With the rapid development of economy, a large amount of metal products are applied to urban and rural construction and industrial life, and the metal products are exposed to air or water and often corroded to different degrees, which seriously affects the long-term use of the metal products. The metal is easy to rust after being corroded, the rust is easy to fall off from the surface of the metal, and at present, the corrosion resistance of a plurality of metal products is poor, so that protective measures are needed to be taken to prevent the surface of the metal product from being corroded and rusted, and the safety and the durability of the metal product in the designed service life can be ensured.
The antirust paint is a coating capable of protecting metal surface from chemical or electrochemical corrosion of atmosphere, seawater and the like. It is mainly divided into two main categories of physical and chemical antirust paints. The physical antirust paint mainly forms a compact paint film by properly matching the pigment and the paint vehicle so as to prevent corrosive substances such as iron oxide red, aluminum powder, graphite antirust paint and the like from invading; the chemical antirust paint mainly depends on the chemical antirust action of antirust pigment, such as red lead, zinc yellow antirust paint, etc.

The corrosion problem of steel is concerned by people, about 2 trillion corrosion loss is caused in China every year, and in order to reduce the corrosion loss, some corrosion-resistant coatings appear, wherein the corrosion-resistant coatings are one of the most used coatings as protective layers and are divided into red lead paint, iron red alcohol paint, iron red phenolic paint, transparent paint, gray paint, zinc yellow paint and the like.
