Abstract

The invention relates to a seawater corrosion-resistant epoxy paint and a manufacturing method thereof. The manufacturing method comprises the following steps of adding modified phenolic epoxy resin and bisphenol-F-epoxy resin into a mixed solvent of dimethylbenzene, diacetone alcohol and n-butyl alcohol; adding titanium dioxide, aluminium triphosphate, alumina powder, silica micropowder, sericite powder, carbon black, an aluminate coupling agent, polymethyl alkyl siloxane solution and polyamide wax into the mixture; blending, stirring and grinding the materials to prepare A liquid of the seawater corrosion-resistant paint; adding aliphatic amine and modified phenolic amine into mixed solution of absolute ethyl alcohol and dimethylbenzene to prepare B liquid; and mixing the A liquid and the B liquid to prepare the seawater corrosion-resistant epoxy paint. The paint can be used for curing at 0 DEG C, has excellent storage stability and very good adhesion, abrasion resistance, flushing resistance and seawater resistance, and can be applied to splashing areas and underwater corrosion resistance of ships, marine platforms, marine work steel structures and the like.

Description

technical field [0001] The invention relates to the technical field of seawater anticorrosion coatings, in particular to a seawater corrosion-resistant epoxy coating which can be used in splash zones of ships, offshore platforms and marine steel structures, etc., and for underwater anticorrosion and a manufacturing method thereof. Background technique [0002] The marine environment is a complex corrosive environment. In this environment, seawater itself is a strong corrosive medium. At the same time, waves, waves, tides, and currents produce low-frequency reciprocating stress and impact on metal components. In addition, marine microorganisms, Attached organisms and their metabolites can directly or indirectly accelerate the corrosion process. Marine corrosion is mainly local corrosion, that is, corrosion that occurs in a small area starting from the surface of the component, such as galvanic corrosion, pitting corrosion, and crevice corrosion. In addition, there are low-fr...
