The present invention relates to an eco-friendly buoy made of a foamed molded body incorporating an air bag and a method for manufacturing the same, and more specifically, after forming a synthetic resin such as epp, eps to form a hollow in the inner diameter by foaming and maintaining the shape of the buoy An eco-friendly buoy made of a foamed molded body with a built-in air bag that prevents loss of buoyancy even if the foamed molded body is damaged by inserting air into the hollow and injecting air into it and providing a solid eco-friendly buoy by coating the outer diameter with a cylindrical coating member. And its manufacturing method. The present invention is made of any one of foam molding and injection and blower molding, and in the buoy in which the binding groove 13 is formed on the outer diameter, And the pocket space 11 is formed in the center of the inner diameter, the side space 12 is formed on both sides of the pocket space 11, and the foamed molded body 10 to be combined by a half； It is inserted into the pocket space (11) and the side space (12) with an insertion hole (14) molded in one part of the foamed molded body (10), and is made of a five-fold structure and injects air into the air inlet (36) to provide buoyancy An air bag 30 for adjusting； Characterized in that the outer diameter of the foamed molded body (10) is coated, and the side cover (21) is fixed on both sides, and a cylindrical coating member (20) is welded by the side welding part (22) to the portion where the side cover (21) meets. Is to do it.본 발명은 공기주머니를 내장한 발포 성형체로 이루어진 친환경 부표와 그 제조방법에 관한 것으로, 더욱 상세하게는 epp, eps와 같은 합성수지를 발포에 의해 내경에 중공을 형성하며 부표 형태를 유지하도록 성형한 후 중공에 공기주머니를 삽입해 공기를 주입함으로써 발포 성형체가 파손되더라도 부력이 상실되지 않도록 하고, 외경을 원통 코팅부재로 코팅에 의해 견고한 친환경 부표를 제공하도록 하는 공기주머니를 내장한 발포 성형체로 이루어진 친환경 부표와 그 제조방법에 관한 것이다.본 발명은 발포 성형과 사출 및 블로워몰딩 중 어느 하나로 이루어지며 외경에 결속홈부(13)가 형성되는 부표에 있어서,내경의 중앙에 주머니공간(11)이 형성되고 상기 주머니 공간(11)의 양쪽으로 측면공간(12)이 형성되며 절반을 결합하여 원통형이 되는 발포 성형체(10)와；상기 발포 성형체(10)의 한 부분
