Abstract
The invention discloses an anti-corrosion composite coating composition and application thereof, wherein the anti-corrosion composite coating composition comprises the following components: two-dimensional nano-sheets and film-forming polymer materials; wherein: the composition of the two-dimensional nano sheet comprises a two-dimensional conductive polymer; or comprises a two-dimensional material, and a two-dimensional conductive polymer supported on the two-dimensional material. The technical scheme of the invention well solves the problem that the corrosion resistance of the existing metal material is easy to be reduced in the corrosion resistance process.
Description
Technical Field
The invention relates to the field of electrochemical corrosion protection. More particularly, to an anti-corrosion composite coating and application thereof.
Background
The metal is widely applied to various fields such as civil engineering, ocean engineering, automobile manufacturing, pipeline transportation and the like due to the excellent characteristics of high strength, good ductility, easy processing and the like. While metals are subject to corrosion in a humid environment for a long period of time, this will significantly reduce the strength of the metal material, which is one of the great problems faced during its application. In recent years, corrosion-resistant coatings based on conductive polymer materials such as polyaniline, polypyrrole, polythiophene and the like have been widely used in the field of metal corrosion resistance due to their excellent corrosion resistance. The redox process of the conductive polymer allows binding and rejection of counter ions in response to changes in metal surface potential caused by localized electrochemical reactions caused by corrosion. Depending on the local corrosion conditions, the conductive polymers may be doped and undoped with ions, which are typically inhibitors of the local corrosion process when undoped. However, the problem of oligomer self-aggregation in the polymerization process of the conductive polymer can lead to the occurrence of pores in the corrosion-resistant coating, thereby reducing the barrier property to corrosive ions and further leading to the rapid reduction of the corrosion resistance.
Disclosure of Invention
Based on the problems, the invention aims to provide an anti-corrosion composite coating and application thereof, so as to solve the problem that the anti-corrosion performance is easy to be reduced in the anti-corrosion process of the existing metal material.
In one aspect, the invention provides an anti-corrosion composite coating composition, a two-dimensional nano sheet and a film-forming polymer material;
wherein:
the composition of the two-dimensional nano sheet comprises a two-dimensional conductive polymer; or (b)
Comprising a two-dimensional material, and a two-dimensional conductive polymer supported on the two-dimensional material.
Further, in the two-dimensional nano-sheet, a two-dimensional conductive polymer grows on the surface of the two-dimensional material in an in-situ polymerization mode.
In the invention, the two-dimensional nano-sheets have order. The two-dimensional material not only has excellent mechanical strength, but also has stable chemical property, high specific surface area and nanometer thickness, and good barrier property to oxygen and water; meanwhile, the arrangement of the two-dimensional material in the polymer matrix plays an important role in enhancing the corrosion resistance of the composite coating. When the two-dimensional nano sheet formed by preparing the two-dimensional conductive polymer on the surface of the metal substrate is used for metal corrosion prevention, the arrangement of the two-dimensional nano sheet on the surface of the metal substrate has great potential as a barrier for effectively blocking the diffusion of corrosive substances (such as water molecules, oxygen molecules and chloride ions), and further has a good corrosion prevention effect.
Further, the mass ratio between the two-dimensional nano-sheet and the film-forming polymer material is preferably 10:1-1:1. When the addition amount of the film-forming polymer material is too small, the obtained coating has poor stability in water; when the addition amount of the film-forming polymer material is too large, the coating conductivity decreases, and thus the corrosion resistance decreases.
Further, the two-dimensional nano-sheet has electrothermal or photo-thermal conversion property.
