Abstract

The invention discloses an antiseptic marine paint and a preparation method thereof. The antiseptic marine paint comprises the following raw materials in parts by weight: 30-40 parts of aliphatic polyurethane acrylic resin, 10-15 parts of 4,4'-dicyclohexylmethane diisocyanate, 5-10 parts of a cationic segmented copolymer, 3-5 parts of 2-mercaptopyridine oxide copper, 10-20 parts of cuprous oxide,0.1-0.5 part of graphene oxide, 10-15 parts of an organic solvent, 0.5-0.8 part of nano ferroferric oxide, 3-5 parts of aluminium triphosphate and 8-10 parts of N-methyl-2-pyrrole carbonitrile. The antiseptic marine paint has excellent mechanical property, water resistance and scrubbing resistance, is compact in coating surface and high in adhesive property and can resist long-time corrosion of seawater.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an anti-corrosion marine paint and a preparation 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, and marine microorganisms, attached organisms, and their metabolites are all harmful Corrosion processes produce direct or indirect accelerations. 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. [0003] In the marine environment, when an object is immersed in seawater, micro-fouling occurs first on its surface, that is, micro-organisms such as bacteria attach to the surface of the object, a...
