Anti-fouling are used to prevent the growth of marine organisms on the bottoms of ship’s hulls. These organisms have extremely adverse effects on both speed and fuel consumption. Zinc containing Acrylic or methacrylic copolymers are easily hydrolyzed in seawater. Fouling organisms, which attach on the surface of a paint film, can be eliminated together with the copolymer film by the hydrolysis of the copolymers. In this study, Zinc methyl methacrylate (ZnMA) by using zinc oxide and Methacrylic acid (MAA) was synthesized. And then we used ZnMA and acrylic monomers to develop self-polishing copolymer (SPC). Synthesis and properties of zinc containing resin were investigated by 1H-NMR, gel permeation chromatography (GPC), inductively coupled plasma (ICP) mass and infrared (IR) spectroscopy. The polishing rate was determined by measuring the film thickness after a dynamic immersion test. |
