표면 처리를 통한 친환경 방오 기술 및 실해역 평가 연구

Antifouling paints that inhibit the attachment and contamination of marine organisms mainly use TBT compounds, but because of their toxic components, they cause ecosystem disturbance and environmental destruction problems, so It is necessary to research eco-friendly antifouling paints that are easy to maintain and effective antifouling technologies. In this study, physical surface treatment of silane coating and chemical antifouling technology were applied to the metal surface to secure the stability of the surface of the marine structure and inhibit the attachment and growth of marine organisms. Adhesion of marine organisms was evaluated according to the coating conditions through surface evaluation of the charged material for 15 months in the waters of the west coast of Korea. In accordance with ASTM D6990-05, antifouling properties fouling rates (FR) and physical degradation rates(PDR) were evaluated through visual inspection of the evaluation specimens. As a result of evaluating the antifouling performance of the coated surface, it was confirmed that the antifouling performance was maintained at the 50% level even after 15 months in the sample subjected to physical processing and silane coating.
