Abstract
Antifouling paints have been used to prevent corrosion of the surface of the ship hulls (vessels) and the adhesion of marine organisms from these surfaces. And the development of a new type of antifouling paint resin which has excellent antifouling performance and no persistence in the marine ecology is necessary. In this study, we have studied polyurethane (PU) and waterborne polyurethane (WPU) resins which are considered to be applied as a new antifouling paint matrix. PU and WPU resins were synthesized by 4,4'-diphenylmethane diisocyanate (MDI), 2,2'-bis(hydroxymethyl) butyric acid (DMBA), 1,4-butanediol, polyethylene glycol (PEG) as ether type polyol and poly(tetramethylene adipate) glycol (PTAd) as ester type polyol. And then quaternary ammonium salts (QAS) which are effective biocides were substituted. After that, the synthesized PU and WPU resins were tested by the laser scan micrometer to confirm the self-polishing property with different types of polyol by measuring film thickness in sea water.

선박용 방오도료는 선박 표면의 부식과 선박 표면으로의 해양생물의 부착을 방지하는데, 해양 환경 오염 없이 방오성능이 우수한 방오도료 수지의 개발이 필요한 실정이다. 본 연구에서는 수용성 및 유성의 polyurethane(PU)수지를 합성하고 방오제로써 4가 암모늄 염을 치환시킨 새로운 방오도료 수지를 개발하였다. 그리고 PU 수지의 폴리올로 에테르 계열의 poly(ethylene glycol)(PEG) (수평균 분자량 200과 600) 및 에스터 계열의 poly(tetramethyleneadipate) glycol(PTAd) (수평균 분자량 600)을 사용하여, 해수 침지 하에서의 폴리올 종류에 따른 수용성 및 유성PU 수지의 자기 마모 특성을 평가하였다.
