Problems solved by technology

Because of its serious pollution and great harm to the human body, red lead has been eliminated and banned by many countries; although zinc phosphate antirust pigment is non-toxic, its performance is not ideal, and aluminum tripolyphosphate cannot be used in large quantities due to price reasons. use
A series of non-toxic anti-rust pigments have been introduced abroad, which can be compared with chromate, but the price is too high, and it is rarely used in China
In addition, the commonly used "iron red anti-rust paint" and "red lead anti-rust paint" also have the disadvantage of poor conductivity and cannot be used for workpieces that need to be welded.
[0003] Patent ZL2009100377115 discloses a new type of environmentally friendly high-efficiency anti-rust pigment and its manufacturing method. It is the steel slag fine powder obtained by crushing, magnetic separation, drying, grinding and subdivision of steelmaking steel slag, and then using a chelating coupling agent to Steel slag powder is used for surface treatment, and finally some additives are added to obtain an environmentally friendly anti-rust pigment, but the preparation process is complicated, there are many types of raw materials used, the cost is high, and there is no electrical conductivity
[0004] Patent CN108864790A discloses a graphene composite antirust pigment and its preparation method. The graphene composite antirust pigment includes zinc oxide, industrial phosphoric acid and conductive graphene and / or reduced graphene oxide, silane coupling agent, Emulsifier and solvent, so as to obtain a kind of anti-rust pigment with good anti-rust ability. Although the patent has added conductive materials, the patent application document does not mention whether it has good electrical conductivity.
