Abstract

The present invention provides a method for marine antifouling. The method comprises: coating an object requiring antifouling with an epoxy polyamide anticorrosion coating material; coating an adhesion layer on the anticorrosion coating material layer; and coating a low surface energy antifouling coating material topcoat on the adhesion layer. According to the present invention, the method uses the a low surface energy marine antifouling coating material and uses the three-component organic combination coating matching system, wherein the epoxy polyamide anticorrosion coating material is adopted as the primer, the middle coating is the styrene-butyl acrylate-polysiloxane interpenetrating network adhesion layer, and the upper layer is the low surface energy nanometer inorganic silicon antifouling coating material topcoat; and the excellent adhesion of the epoxy resin to the substrate and the excellent connection effect of the middle coating between the primer and the topcoat are used, and the problems of the adhesion among the steel iron substrate, the anticorrosion primer and the antifouling coating material, the antifouling function and the environmental protection are well solved.

Description

technical field [0001] The invention relates to the field of marine antifouling, in particular to a method for marine antifouling. Background technique [0002] According to data records, there are nearly 20,000 kinds of attached organisms in seas all over the world. The larvae and spores of these periphytons float and swim in the ocean, and when they develop to a certain extent, they will attach, settle and further reproduce on the bottom of ships sailing in the ocean or on the steel structures under the sea. The attachment of these organisms will not only increase the surface roughness of the steel structure, reduce the speed of the ship, increase fuel consumption (up to 30%), but also lead to accelerated corrosion of structural materials and endanger the platform facilities and aquaculture in the water. [0003] Such as: causing blockage of cold water pipelines, increasing the resistance of submarine pipelines, etc. Due to the tension generated by the growth of these or...
