Description
Technical Field
The invention belongs to the technical field of hot galvanizing plate surface treatment, relates to a hot galvanizing surface treatment method with excellent corrosion resistance, and particularly relates to an organic composite passivation treatment liquid for a hot galvanizing plate and a use method thereof.
Background
Hot galvanizing is used as a common surface protection means, and economic and effective protection is provided for the use of steel materials. The zinc layer can be used as a barrier layer to prevent a corrosion medium from contacting the steel base, and can also play a role of a sacrificial anode to slow down the corrosion of the steel base. However, with the increasing demands for corrosion resistance in increasingly severe service environments, the conventional galvanized steel sheet no longer meets the requirements for corrosion resistance of the current generation. In order to further improve the corrosion resistance of the galvanized steel sheet, passivation treatment is usually performed on the surface of the galvanized steel sheet. The most economical and effective surface treatment is chromate passivation technology, the process is simple, the cost is low, the film adhesion is good, the self-repairing effect is achieved, and the process is a classic process for improving the corrosion resistance of the hot-dip galvanized plate. However, chromate coatings containing hexavalent chromium are carcinogenic, and there has been an increasing demand for environmentally friendly chromium-free passivation treatment processes in recent years for safety and environmental concerns.
Currently, the most concerned hot galvanizing surface chromium-free treatment technologies comprise inorganic matter passivation of molybdate, phosphate, silicate, rare earth metal salt and the like, organic matter passivation of phytic acid, silane and the like, and some organic/inorganic composite synergistic passivation technologies. Wherein, after the environment-friendly inorganic passivation treatment (including conversion treatment of molybdate, phosphate, silicate, rare earth metal salt and the like), the corrosion resistance of the film is far lower than that of a chromate passivation film, and the problem of insufficient corrosion resistance exists in the use process; after organic passivation treatment (including phytic acid, silane and the like), although the corrosion resistance of the film is improved, the conductivity of the film is reduced, and the problem of poor grounding property possibly exists when the film is used as a shell of a household appliance; the organic/inorganic composite passivation technology (including silane/rare earth composite film and the like) integrates the advantages of the two, but the metal surface treatment formed by compounding common aqueous resin and inorganic components still has the defects of acid resistance, alkali resistance and salt mist resistance.
Meanwhile, with the increasing demand of domestic industries such as automobiles, household appliances, buildings and the like on galvanized plates with good coating performance, the adhesion problem of the galvanized passivated plates after coating becomes a difficult point restricting subsequent processing and industrial application. Meanwhile, in the coating process, the electrostatic spraying can greatly improve the utilization rate of the coating, and has the characteristics of high spraying efficiency, uniform coating, less pollution and the like, so that the electrostatic spraying is gradually the most popular spraying process applied in production. The principle of electrostatic painting is that a DC high-voltage electricity is applied between a workpiece and a painting tool to generate an electric field, and the paint is uniformly adsorbed on the workpiece by utilizing electrostatic attraction. In this case, in order to make the surface-treated hot-dip galvanized sheet meet the requirements for electrostatic coating, it is necessary to impart good surface conductivity to the hot-dip galvanized passive sheet. Therefore, in order to meet various use requirements of the coating process, the surface treatment technology of the hot-dip galvanized sheet is gradually developed to multifunctional composite coatings, such as high-performance coatings integrating corrosion resistance, conductivity, coating property and the like.
If the patent numbers are: CN107400883A, name: the invention discloses a silane/zirconium composite treating agent before coating a galvanized sheet and a preparation method thereof, and discloses a silane/zirconium composite treating agent before coating a galvanized sheet and a preparation method thereof. The silane composite film obtained by the composite treating agent has excellent bonding performance with organic paint and good coating performance.
As patent numbers: CN102251239B, name: the invention discloses a galvanized sheet color-coating chromium-free passivation solution based on waterborne epoxy resin composition, which comprises the following components in percentage by liter: organic resin: 100-300 g/L; organic acid: 20-75 g/L; inorganic salts: 2-6 g/L; oxidizing agent: 3-12 g/L, pH value regulator: a proper amount; deionized water: and (4) the balance. Phosphoric acid is used as a pH value regulator to regulate the pH value of the chromium-free passivation solution to 2-3. According to the invention, the waterborne epoxy resin, the organic acid, the inorganic salt and the oxidant are organically combined and act on the galvanized plate to form the compact organic-inorganic composite passive film, and the passive film can be directly coated with the finish paint, so that the color coating process of the galvanized plate is simplified, and the cost is reduced.
As patent numbers: CN102070927B, the name is: the invention discloses an aqueous surface treating agent for color coating pretreatment of a galvanized sheet, which comprises the following components in percentage by mass: 20-60% of water-based resin; 1-5% of organosilane; 0.5 to 2.5 percent of inorganic corrosion inhibitor; 0.5 to 3 percent of sealing agent; 1-3 of an accelerant; deionized water and the balance. According to the invention, the inorganic corrosion inhibitor, the nano particles, the organic silane and the water-based resin are organically combined to form the composite passive film, so that the coating performance of the galvanized sheet after surface treatment is improved, and the requirements of a color coating process can be met.
The organic/inorganic passivation treatment method can realize the effect of enhancing the binding force of the organic coating and the hot-dip galvanized sheet, however, compared with the traditional chromate passivation, the organic/inorganic passivation treatment method has the defect of insufficient corrosion resistance, and meanwhile, in order to meet the requirement of electrostatic coating, a film layer after passivation treatment also needs to meet a certain conductivity requirement. Therefore, it is very necessary to develop a passivation process for coating which has excellent corrosion resistance and conductivity.
