Abstract

The invention relates to a self-polishing antifouling paint and a preparation method thereof. Every 100 parts by mass of the antifouling paint is composed of 18-24 parts of solid-based resin, 50-55 parts of antifouling compound, 0.5-1.5 parts of graphene microchip, 3-6 parts of pigment and filler, 1-2 parts of dispersing agent, 1-2 parts of organobentonite and the balance of organic solvent. The resin is composed of a hydroxy acrylic resin, a zinc acrylate resin and rosin. The antifouling compound is composed of zinc pyrithione, 4,5-dichloro-2-n-octyl-4-isothiazolinyl-3-one, cuprous oxide and zinc oxide. The preparation method comprises the following steps: respectively preparing the graphene microchip-zinc oxide-hydroxy acrylic resin slurry and cuprous oxide-rosin-zinc acrylate slurry, and mixing to obtain the self-polishing antifouling paint. The obtained self-polishing antifouling paint product has the advantages of stable quality, long antifouling period, favorable polishing effect, high strength, cracking resistance and low VOC (volatile organic compound).

Description

technical field [0001] The invention relates to a self-polishing antifouling paint and a preparation method thereof, which is especially suitable for ship bottom antifouling. Background technique [0002] The attachment and fouling of marine organisms to the bottom of the ship increases the roughness of the outer surface of the bottom of the ship, increases the navigation resistance, reduces the speed of the ship, and increases the fuel consumption. In addition, the adhesion and fouling of marine organisms to the hull also accelerates the corrosion of the hull, shortens the service life of the ship, and poses a hazard to navigation safety. According to incomplete estimates, the economic loss caused by marine biofouling in the world exceeds 1 billion US dollars every year. Therefore, preventing the attachment and fouling of marine organisms has always been an important task in naval defense construction, marine transportation and marine engineering development. In order to ...
