The present invention relates to an eco-friendly buoy that replaces Styrofoam, and specifically to the eco-friendly buoy, comprising: a non-woven fabric body formed by fitting a cylindrical right cover with one side open and the other closed and a cylindrical left cover with one side open and the other closed to each other; an inner frame formed inside the non-woven fabric body to preserve the shape of the non-woven fabric body; and a polyurea coating layer formed on the outside of the non-woven fabric body. As the polyurea coating layer is formed by applying and curing a coating composition including polyurea, styrene-butadiene rubber, carbon fiber, fullerene, graphene, and a plasticizer, Styrofoam is not used so that the present invention is eco-friendly and can realize excellent elasticity, impact resistance, water resistance, and temperature stability.

    본 발명은 스티로폼을 대체하는 친환경적인 부표에 관한 것으로, 구체적으로, 본 발명의 부표는 일면은 개방되며 타면은 폐쇄된 원통형의 우측커버와, 일면은 개방되고 타면은 폐쇄된 원통형의 좌측커버가 서로 끼움 결합되어 형성되는 부직포 본체; 상기 부직포 본체 내부에 형성되어 상기 부직포 본체의 형태를 보존하는 내부 프레임; 및 상기 부직포 본체 외부에 형성되는 폴리우레아 코팅층;을 포함하며, 상기 폴리우레아 코팅층은 폴리우레아, 스티렌-부타디엔 고무, 탄소섬유, 풀러렌, 그래핀 및 가소제를 포함하는 코팅 조성물을 도포 및 경화하여 형성된 것임에 따라, 스티로폼을 사용하지 않아 친환경적이면서도 우수한 탄성력, 내충격성, 내수성, 온도 안정성 등을 구현할 수 있다.
