The present invention relates to an eco-friendly polypropylene buoy and to a manufacturing method thereof. According to the present invention, the marine buoy comprises a foam core layer, wherein the foam core layer comprises: a polypropylene resin including at least one of a homopolymer polypropylene (homo PP) resin or a propylene-ethylene copolymer resin; and an additive including at least one of ethylene propylene diene monomer (EPDM) rubber or polyolefin elastomer (POE). In the present invention, the buoy and manufacturing method thereof have high productivity and low manufacturing cost by manufacturing the buoy comprising a high magnification foam core layer and a thin non-foamed skin layer using a polypropylene foam extrusion method in a continuous process.

    본 발명은, 친환경 폴리프로필렌 부표 및 그 제조 방법에 관한 것이다. 본 발명에 의하면, 해상용 부표에 있어서, 발포 코어층을 포함하고, 상기 발포 코어층은 호모 폴리프로필렌(homopolymer polypropylene, homo PP) 수지 또는 프로필렌-에틸렌 공중합(propylene-ethylene copolymer) 수지 중 적어도 하나를 포함하는 폴리프로필렌 수지; 및 에틸렌 프로필렌 고무(ethylene propylene diene monomer rubber, EPDM 고무) 또는 폴리올레핀 엘라스토머(polyolefin elastomer, POE) 중 적어도 하나를 포함하는 첨가제로 구성된 해상용 부표가 제공된다. 본 발명은 폴리프로필렌 발포 압출 공법을 사용하여 고배율 발포 코어층 및 박막의 비발포 스킨층을 포함하는 부표를 연속 공정으로 제조함으로써, 생산성이 높고 제조 단가가 낮은 부표 및 그 제조방법을 제공할 수 있다.
