Abstract

The invention belongs to the technical field of antifouling paint and in particular relates to organic silicon modified acrylic resin antifouling paint. The organic silicon modified acrylic resin antifouling paint comprises the following raw material components: organic silicon modified acrylic resin, graphene oxide, a silicate compound antifouling agent, a thickening agent, a dispersant, a flatting agent, a coupling agent, a mixed solvent and other pigment and filler, wherein the content of each raw material component is as follows in parts by mass: 25 to 50 parts of the organic silicon modified acrylic resin, 0.5 to 2 parts of the graphene oxide, 15 to 40 parts of the silicate compound antifouling agent, 0.3 to 2 parts of the thickening agent, 0.5 to 2 parts of the dispersant, 0.2 to 2 parts of the flatting agent, 0.1 to 1.5 parts of the coupling agent, 10 to 30 parts of the other pigment and filler and 15 to 35 parts of the mixed solvent. The antifouling paint provided by the invention has excellent staining resistance, weather resistance, adhesive force and the like, and a paint film has good density and mechanical performance. The organic silicon modified acrylic resin antifouling paint can be widely applied to various ocean facility fields including ocean ships, ocean detectors and the like.

Description

technical field [0001] The invention belongs to the technical field of antifouling coatings, and in particular relates to an organic silicon modified acrylic resin antifouling coating and a preparation method thereof. Background technique [0002] One of the first challenges encountered in offshore operations is marine corrosion. Ships, offshore drilling platforms, buoys, mariculture cages, marine detection instruments and other marine facilities are not only corroded by salt in the sea, but also corroded by a large number of marine attached organisms in the sea when they are operating at sea. This type of marine organisms mainly attaches to the hull and the parts below the waterline of marine facilities, reproduces in large numbers, destroys the structure of the anticorrosion layer on the surface of the components of ships and marine facilities, causes accelerated local corrosion of metals, brings great harm to offshore operations, and reduces the And the service life of m...
