Product Description

Zinc phosphate aluminum tripolyphosphate is used as a chemical corrosion inhibitor in paint



The anti-rust pigments with chemical corrosion inhibition effect change the properties of the surface or the characteristics of the reaction products according to the chemical reaction to achieve the purpose of anti-rust. Anti-rust pigments with chemical corrosion inhibitors can interact with metal surfaces such as passivation and phosphating to produce a new surface film, passivation film, phosphate film and so on. The electrode potential of these films is more positive than that of the original metal, so that part or all of the metal surface avoids the possibility of becoming an anode; in addition, there are many micropores on the film to facilitate the adhesion of the paint film. Anti-rust pigments can also chemically react with certain paint ingredients to form compounds with stable performance, good water resistance and low permeability.



The most important anti-rust pigment in phosphate is zinc phosphate [Zn3(PO4)•2H2O], which can combine with the hydroxyl and carboxyl groups in the coating, and can also generate Fe[Zn3(PO4)] on the metal surface. The formed pigment-paint-substrate polymer complex prevents the formation and development of rust. After modifying the particle size, distribution and chemical composition of the zinc phosphate raw material, its performance can be equivalent to that of zinc chromate.
Aluminum tripolyphosphate is a new type of anti-rust pigment newly developed in recent years. It is white, slightly soluble in water, and ionizes when dissolved under the coating, and combines with metal ions at the anode to form an insoluble passive film. The film has high hardness and adheres. firm. If trimer ions are hydrolyzed into dimer or phosphate ions, they still contain reactive groups, so a similar passivation film can also be formed. Aluminum tripolyphosphate can be used in water-based and solvent-based coating systems.
