Abstract

내식성, 내후성, 가공성을 아울러 지니는 복합금속판 및 그 제조방법을 제공한다.
금속표면에 화성처리를 행한 후 그 위에 밑칠로서 유기수지계 도료를 도장, 건조하고 이어서 그 위에 변성 폴리올레핀수지의 접착층과 폴리올렌핀수지층의 2층으로 이루어지는 중간층을 50~300 마이크로미터 두께로 형성시켜 폴리올레핀수지층의 표면을 화염처리 또는 코로나방전처리로 표면개질하고 관능기중의 산소량과 표면의 탄소량의 비를 나타내는 O/C 치로 0.05~0.30의 관능기를 생성시키고 다시 덧칠로서 우레탄경화형 폴리에스테르도료 또는 우레탄경화형 불소도료를 8~36 마이크로미터 두께로 도장, 건조시켜서 얻어진 복합금속판.
