Description

부자 및 그 제조방법{Environment-friendly buoy and method to manufacture the same}Buoy and its manufacturing method {Environment-friendly buoy and method to manufacture the same}

본 발명은 부자 및 그 제조방법에 관한 것으로, 더욱 상세하게는 해양에서 사용되는 폐스티로폼을 활용하여 부자를 제조함으로써, 폐스티로폼으로 인한 해양과 지상의 오염원을 원천적으로 제거하여 해양환경오염 문제를 해결할 수 있도록 하는 부자 및 그 제조방법에 관한 것이다.The present invention relates to a float and a method for manufacturing the same, and more particularly, by manufacturing a float using waste Styrofoam used in the sea, to fundamentally remove pollution sources in the sea and on the ground caused by waste Styrofoam to solve the problem of marine environmental pollution It relates to a rich and a method for manufacturing the same.

부자란, 해상에 띄워 사용할 수 있게 형성되어 양식장이나 어망 등이 해상에 위치될 수 있도록 이용되는 것을 말하는 것이다.The buoy refers to a thing that is formed so that it can be floated on the sea and used so that aquaculture farms or fishing nets can be located in the sea.

이러한 부자는, 해상에 띄워 사용할 수 있도록 가벼우면서도 일정 부분 부력을 형성할 수 있는 재질로 형성되는 것이 바람직한 것이다.It is preferable that these floats be formed of a material capable of forming a certain portion of buoyancy while being lightweight so that they can be used by floating on the sea.

이를 위해 종래에는, 가벼우면서도 손쉽게 형성하여 사용할 수 있고, 제조단가가 저렴한 스티로폼이 주로 사용되고 있다.For this purpose, conventionally, styrofoam, which is light and can be easily formed and used, and has a low manufacturing cost, is mainly used.

그러나 위와 같은 종래의 스티로폼 부자는 부력의 우수성, 저렴한 가격 등의 장점이 있기는 하나, 부력확보를 위해 저밀도 스티로폼을 사용하게 됨으로써, 쉽게 부서지는 특유의 단점으로 인해 내구성이 약하여, 해상에서 장기간 사용하는 경우에는 손쉽게 파손되어 해양을 오염시키는 문제가 있었으며, 위와 같은 해양 오염을 방지하고자 해상에 설치된 스티로폼을 수거하여 재사용하고자 하는 경우에는 스티로폼의 가공과정이 손쉽게 이루어지기 힘들어 수거된 스티로폼을 지상에 쌓아놓은 상태로 보관해야 함으로써, 지상의 환경오염을 일으킬 수 있는 문제가 있었다.However, the above conventional styrofoam floats have advantages such as superior buoyancy and low price, but by using low-density styrofoam to secure buoyancy, their durability is weak due to the unique disadvantage of being easily broken, so it can be used for a long time at sea. In this case, there was a problem that it was easily damaged and polluted the sea, and in the case of collecting and reusing the styrofoam installed in the sea to prevent the above-mentioned marine pollution, the processing process of styrofoam is difficult, so the collected styrofoam is stacked on the ground There was a problem that could cause environmental pollution on the ground by being stored as

이에 따라, 최근에는 문헌(1)에서와 같이, 발포폴리프로필렌을 이용하여 형성된 부자나, 문헌(2)에서와 같이, 폴리프로필렌 코팅층이 형성된 부자 등이 제안된 바 있으나, 이러한 부자들은 해상에 설치된 스티로폼 부자를 대체하는 용도로사용되는 것으로, 해상에 이미 설치되어 있는 스티로폼 부자를 재활용하여 사용하기는 어려운 문제가 있었고, 스티로폼 부자로 인한 환경오염 문제를 근원적으로 해결하기는 어려운 문제가 있었던 것이다.Accordingly, recently, as in the document (1), a float formed using expanded polypropylene or, as in the document (2), a float formed with a polypropylene coating layer, etc. have been proposed, but these floats are installed at sea As it is used to replace the Styrofoam float, it was difficult to recycle and use the Styrofoam float already installed in the sea, and it was difficult to fundamentally solve the environmental pollution problem caused by the Styrofoam float.
