| titleOfInvention | Pretreatment liquid capable of forming water-washable natural color conversion film on metal surface and preparation method thereof |
| abstract | The invention discloses a pretreatment liquid capable of forming a water-washable natural color conversion film on a metal surface and a preparation method thereof. The pretreatment liquid is composed of the following components: 0-10% of a chelating agent, and 1-12% of a modified chelating agent , auxiliary salt 0.1-0.2%, auxiliary 0.5-1%, complexing agent 0.05-2%, neutralizing agent 0-10%, and the balance is water; the modified chelating agent includes C, N, O, At least three elements among H, P, S, B, Na, Ca, Mg, Fe, Zn, Cl, F, and Si. The metal surface treatment liquid of the invention contains few kinds of substances, is simple and easy to operate, and the waste liquid is environmentally friendly and pollution-free. The treated workpiece can be washed with water to obtain a colorless and uniform natural color conversion film, which keeps the appearance of the metal workpiece from being damaged, and greatly expands the application range of the pretreatment liquid. The conversion film obtained by the invention greatly increases the surface roughness of the base material, the film layer is firmly combined with the base material, and the adhesion and corrosion resistance between the coating and the surface of the base material are effectively improved. |
