BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a buoy for wrapping and shaping a concave-convex internal reinforcing body of a synthetic resin, and more particularly, The inner reinforcing body in which the groove portion and the protruding portion are formed continuously is cut to a predetermined length, and the side finishing plate is fixed by welding from both sides. Thereafter, the inner reinforcing body is wrapped around the inner reinforcing body by heat shrinkage The present invention relates to a buoy for wrapping and molding a synthetic resin ridged internal reinforcing body for preventing contamination of the sea. The present invention includes an internal reinforcing body 10 having a space 12 in an inner diameter and a groove 14 and a protrusion 13 formed continuously in the outer diameter of the space 12, And a side finishing plate (20) fused and fixed at both ends of the inner reinforcing body (10) A circular finishing sheet 40 for covering and fixing the outer side of the side finishing plate 20 is formed, A mesh sheet 30 which is heat-shrunk by heating at an outer diameter of the inner reinforcing body 10 so as to integrally coat and form fixing grooves 51 on both sides of the inner reinforcing body 10 and a protrusion 32 on the outer side of the circular finishing sheet 40, (50) integrally fused and fixed thereto； 10 to 30 parts by weight of mPE-2, 50 to 87 parts by weight of low-density polyethylene, 1 to 3 parts by weight of a UV stabilizer, 1 to 3 parts by weight of a UV blocking agent, 1 to 5 parts by weight.본 발명은 합성수지 요철형 내부 보강 몸체를 감싸 성형하는 부표에 관한 것으로, 더욱 상세하게는 폴리에틸렌(PE), 폴리프로필렌(PP), 폴리염화비닐(PVC), FRP 중 어느 하나를 이용하여 일정한 간격에서 홈부와 돌출부가 연속해서 형성되는 내부 보강 몸체를 소정의 길이로 절단하여 양쪽에서 측면 마감판을 용접으로 고정한 후 전체면의 외측에 내부로 물이 스며들지 않으면서 내부 보강 몸체에 열수축으로 감싸 고정하여 바다의 오염을 방지할 수 있도록 하는 합성수지 요철형 내부 보강 몸체를 감싸 성형하는 부표에 관한 것이다.이러한 본 발명은 내경에 공간(12)을 갖고, 상기 공간(12)의 외경에서 홈부(14)와 돌출부(13)가 연속해서 형성되는 내부 보강 몸체(10)를 포함하며,상기 내부 보강 몸체(10)
