Abstract

The invention provides marine antifouling paint. The marine antifouling paint comprises a component A and a component B, wherein the component A comprises the following components in parts by weight:15 to 30 parts of epoxy resin, 1 to 5 parts of pigment, 5 to 8 parts of a silane coupling agent, 2 to 5 parts of an aid, 3 to 6 parts of a filler, and 15 to 25 parts of a solvent; the component B comprises the following components in parts by weight: 20 to 40 parts of an epoxy resin curing agent, 5 to 10 parts of an antifouling agent, and 10 to 20 parts of a solvent; and a mass ratio of the component A to the component B is (2.5 to 4): 1, and the antifouling agent is a combination of a compound I and a compound II. The marine antifouling paint provided by the invention is high in marine bioerosion resistance and high in storage stability, still uniform by virtue of stirring after being stored for 12 months, free from the phenomenon such as coarse particles, hard or colloidal precipitates,scaling, hard pigment settling and the like and excellent in performance.

Description

technical field [0001] The invention belongs to the field of coatings, and relates to a marine antifouling coating and a preparation method and application thereof. Background technique [0002] The hulls below the waterline of ships and wharves have been in contact with seawater for a long time and are corroded by seawater; the attachment of marine organisms reduces the speed of the ship, accelerates the corrosion of the hull, damages the underwater platform facilities, and blocks the cooling water pipeline of the power plant. Coating it with various marine antifouling coatings can prevent the above problems from occurring. [0003] Marine antifouling paint is a special kind of paint, the main function is to prevent marine organisms from fouling through the gradual seepage of antifouling agents (poisons) in the paint film. However, the earlier antifouling coatings also caused secondary pollution to the marine environment while inhibiting the adhesion of marine organisms. ...
