Description
Technical Field
The invention relates to the technical field of surface treatment, in particular to a surface treatment process for a metal shelf.
Background
The metal is subject to chemical, electrochemical or physical interaction with the environment medium in which the metal is located, so that the metal is deteriorated and deteriorated, namely metal corrosion, which is quite common. The corrosion prevention is to protect metal objects which are easy to rust by adopting various means to achieve the purpose of prolonging the service life of the metal objects, and methods such as chemical corrosion prevention, physical corrosion prevention, electrochemical corrosion prevention and the like are generally adopted.
At present, when the shelf is subjected to anticorrosion treatment, a barrier coating, particularly a super-hydrophobic coating is usually coated on the surface of the shelf, the super-hydrophobic coating can effectively prevent carbon steel from being in direct contact with a corrosive medium, and up to now, a plurality of methods can be used for preparing the super-hydrophobic coating on the metal surface, such as spraying, laser manufacturing, hydrothermal, self-assembly, anodic oxidation and electrostatic spinning.
The electrophoresis technology has the advantages of high resource utilization rate, simple process, low requirement on the surface shape of a substrate and the like, and is widely applied to the preparation of films and coatings. However, the electrophoresis method is rarely used for the preparation of a superhydrophobic thin film. Ohwei et al (proceedings of Artificial Crystal, 2009,38, supplement, 137-140) adopt electrophoresis technology to deposit ZnO film, and then realize super-hydrophobization through modification of low surface energy substances; hercules et al (electromachining and molding, 2014,6, 29-32) successfully prepare the nickel/polytetrafluoroethylene super-hydrophobic film by an electrophoresis-electrodeposition composite method. Although the coating deposited on the surface may prevent penetration of water droplets, the coating is not resistant to attack by corrosive ions, which will react with the metal layer to form corrosive compounds.
Disclosure of Invention
The invention aims to solve the technical problem that the superhydrophobic coating prepared by the conventional electrophoresis method is difficult to resist corrosion of corrosive ions, and provides a method for electrophoretic treatment of a shelf, which is low in cost, simple to operate and suitable for industrialization, so that the shelf with the superhydrophobic anticorrosive coating on the surface can be obtained.
In order to realize the purpose, the invention adopts the technical scheme that:

(3) Electrophoretic deposition: placing the electrolyte solution in an electrophoresis processing device, taking the shelf component as a cathode and the graphite foil as an anode, carrying out electrophoretic deposition, and depositing a zinc oxide/polyaniline-graphene coating on the surface of the shelf component;
(4) Cleaning and drying: the polyaniline/zinc oxide-graphene coated shelf parts were rinsed with industrial ethanol and dried at room temperature.
Furthermore, the polyaniline/zinc oxide compound is prepared by coordinating aniline monomer and zinc ions and then carrying out hydrothermal reaction.

Further, the volume ratio of acetone to iodine in the step (2) is 1:1.1-1.3.
Further, in the step (2), the mass concentration of the polyaniline/zinc oxide compound in acetone is 10mg/L-30mg/L.
Further, the mass concentration of the graphene in the acetone in the step (2) is 2mg/L-6mg/L.
Further, the distance between the cathode and the anode in the step (2) is 10-15cm.
Further, the conditions of the electrophoretic deposition in the step (3) are as follows: stirring is continuously carried out for 1-1.5h under the constant voltage of 60-80V. Compared with the prior art, the method has the beneficial effects that:
(1) According to the surface treatment process of the metal shelf, the polyaniline/zinc oxide compound and the stearic acid are simultaneously deposited on the surface of the shelf component, the polyaniline/zinc oxide compound generates a micro-nano rough structure on the surface of the shelf, the water attachment is reduced, the water contact angle is increased, a layer of compact passivation film with protection capability can be formed on the polyaniline and the metal surface, the metal is in a passivation state, the metal is protected, the corrosion of corrosive ions is prevented, electrons can be transferred due to the existence of the graphene, and the formation of the passivation film is further promoted.
(2) The invention relates to a metal shelf surface treatment process, which adjusts zeta potential of polyaniline/zinc oxide and graphene in acetone by adding iodine, when the iodine is introduced, the iodine reacts with the acetone to generate protons, the protons are then adsorbed on the surfaces of the polyaniline/zinc oxide and the graphene, particles are charged to generate similar zeta potential, thereby leading to similar electrophoretic mobility, forming uniform coating, and the increased electrostatic repulsion makes electrolyte solution more stable.
