Description
Technical Field
The invention relates to the field of paint, in particular to an epoxy paint with high corrosion resistance and high transparency and a preparation method thereof.
Background
In order to develop abundant ocean resources, ocean engineering equipment must have strong durability and stability to withstand the harsh corrosive environment of the ocean. Therefore, improving the corrosion resistance of equipment in extremely corrosive environments has been the focus of research. Metal base materials such as alloy steel and carbon steel are widely applied to various industries; however, they are also susceptible to corrosion. To ensure optimal protection of the metal substrate, a suitable surface barrier, such as an organic coating, must be applied. The application of organic coatings is an effective method for solving the problem of corrosion of the steel structure in the atmospheric environment. The durability and lifetime of these coatings depends on various factors including the coating chemistry, the density of the crosslinks within the coating, and its adhesion to the metal surface, etc. Among the numerous coatings, epoxy coatings have a broad application potential due to their high crosslink density and affinity for metal surfaces. However, corrosive materials diffuse into the epoxy coating through inherent pores or scratches and penetrate the metal/coating interface, initiating corrosion reactions at the anode and cathode sites, severely damaging the coating, reducing the useful life of the metal substrate. The flaky anti-corrosion pigment and filler can be added to effectively block water molecules and oxygen molecules from entering the coating and delay corrosion reaction, so that the anti-corrosion capability of the coating is improved and the service life of metal is prolonged; in addition, the introduction of various corrosion inhibitors can also improve the corrosion resistance of the coating. Corrosion inhibitors slow corrosion primarily by depositing or adsorbing on metal substrates. Therefore, the corrosion resistance of the metal matrix can be remarkably improved by adopting different types of corrosion inhibitors to cooperate with each other.
