Preparation And Research Of New Low Surface Energy Antifouling Coating Based On The Fluorine-silicon Modified

Ship is an important sea transport. Due to year-round navigation in the ocean, marine lifewill be attached to the hull, which brings the ship’s voyage the tremendous resistance,resulting in huge economic losses. The most effective way to prevent ships fouling by marineorganisms is coated with antifouling paint so far. Marine antifouling coatings function as aspecial protective coating, for coating the bottom, marine structures, offshore oil platformsand other places, in order to prevent the adhesion of marine fouling. Traditional marineanti-fouling paint though the release of toxic to prevent adhesion of the sea creatures on themarine environment cause serious pollution, the development of new environmentallyfriendly antifouling paints is particularly important.The organic fluorine was used with a low surface energy properties monomer, styrene,ethylene and so on, to modifie acrylic resin on a wide range using radical polymerization andsynthesis the organic fluorine modified epoxy acrylate resin, which has a low surface energyproperties. Discuss the content of each monomer and polymerization process of the resinperformance impact on the synthesis of organic fluorine modified acrylic resin for adhesionand contact angle measuring instrument with a resin coating on the performance of routinetests, to be modified resin formulations and the best synthesis of the best: hard and softmonomer ratio of0.8, fluorine content of monomer of12%, ethylene content of10%styrenecontent of10%, acrylic acid content of6%, with themethod of delay dropping temperaturesynthesis of monomer and initiator. Meanwhile, the resin as the film-forming material,mechanical mixed the modified silica sol, the network of silicon will be introduced into theinorganic polymer network to preparate the organic-inorganic hybrid marine antifoulingcoatings throughout both networks intersect. We examine the effect of pigment to binder ratio,nano-SiO₂addition amount, the amount of silicon, epoxy and paint preparation processperformance. The results show that10%epoxy getting the effect best affter one month inseawater plate antifouling. pigment to binder ratio of1.4, the amount of nano-SiO₂of12％,silica content of30%and we obtain the film contact angle reached150°, so that the coatinghas a super-hydrophobic properties. The coating adhesion, impact strength and hardness ofconventional performance was tested and the macro and micro morphology on the coatingsurface were analyzed. We studied the relationship during the content of SiO₂nanoparticles,coating microstructure and super-hydrophobic surface characteristics on the basic theory ofinfiltration mechanism and the mechanism of its effects.
