Description

친환경소재를 이용한 부력체 및 그 제조방법{Buoyant body using eco-friendly materials and manufacturing method thereof}Buoyant body using eco-friendly materials and manufacturing method thereof}

본 발명은 친환경소재를 이용한 부력체 및 그 제조방법에 관한 것으로서, 보다 상세하게는 대나무, 옥수수대, 갈대, 볏짚 등 다공성 경량 자연소재를 분쇄하여 이를 멸균하여 성형한 후 규산염액으로 코팅하여 PE-PP소재의 외장재로 포장된 친환경소재를 이용한 부력체 및 그 제조방법에 관한 것이다.The present invention relates to a buoyancy body using an eco-friendly material and a method for manufacturing the same, and more particularly, a porous lightweight natural material such as bamboo, cornstalk, reed, rice straw is pulverized, sterilized and molded, and then coated with a silicate solution. It relates to a buoyancy body using an eco-friendly material packaged with a PP material and a manufacturing method thereof.

일반적으로 부력체 또는 부표는 인근 해역에서 양식장을 구분하여 표시하기 위해 해상에 띄워 사용하거나, 상기 부표의 몸체에 그물이나 줄과 같은 양식구조물을 연결하여 김이나 미역 또는 굴 등과 같은 부착성 생물을 해수중에서 양식하는 데에 사용하고 있다.In general, buoyancy bodies or buoys are used by floating on the sea to identify and mark aquaculture farms in nearby sea areas, or by connecting aquaculture structures such as nets or strings to the body of the buoys, attaching organisms such as seaweed, seaweed or oysters are seawater. It is used for farming in the middle.

현재 사용되고 있는 부표는 폴리스티렌 폼(polystrene foam, 이하 '스티로폼') 재질의 것과 폴리에틸렌 발포수지 재질의 것으로 크게 나눌 수 있다.The currently used buoys can be broadly divided into those made of polystyrene foam (hereinafter referred to as'styrofoam') and those made of polyethylene foam.

상기 스티로폼 재질의 부표는 가볍고 부력이 강하며 부식성이 없고 설치작업이 용이하며 비용이 저렴하기 때문에 많이 이용되고 있으나, 재질이 약하여 마모가 쉽고, 장기간 사용시 수분이 흡수되면서 부력을 잃게 되는 문제점이 있었다.The buoy made of the styrofoam material is light, has strong buoyancy, is not corrosive, is easy to install, and is used a lot because it is inexpensive, but there is a problem in that the material is weak and is easy to wear and loses buoyancy as moisture is absorbed during long-term use.

그리고, 수면과의 마찰 또는 수면 위를 떠다니는 물체와 충돌되었을 때 파손되기 쉽고, 스티로폼 자체가 기공이 크고 많기 때문에 해수에서 장시간 사용시 해수의 응집으로 부력이 저하되어 부표로서의 본래 기능을 발휘하지 못하게 되며, 부표의 파손에 의한 스티로폼 파편이 수면에 부유하게 됨에 따라 오염의 원인이 되는 문제점이 있었다.In addition, it is easy to be damaged when friction with the surface or colliding with an object floating on the surface of the water.Since the styrofoam itself has large and many pores, when used in seawater for a long time, the buoyancy of the seawater decreases due to the aggregation of seawater, preventing it from exhibiting its original function as a buoy , As the styrofoam fragments due to the breakage of the buoy floated on the water surface, there was a problem that caused contamination.

또한, 폴리에틸렌 발포수지 재질의 부표는 스티로폼 재질의 부표에 비해 내파열성 및 인장강도가 우수하므로 각종 원인에 의한 파손 우려는 적으나, 폴리에틸렌 발포수지 자체가 물을 흡수하는 성질을 가지고 있기 때문에, 폴리에틸렌 발포수지 재질의 부표 또한 장시간 사용시 부표의 부력이 약해지는 문제점이 있다.In addition, since the buoy made of polyethylene foam resin is superior to the buoy made of styrofoam, it is less likely to be damaged due to various causes, but because the polyethylene foam resin itself has the property of absorbing water, polyethylene foaming Also, the buoyancy of the buoy is weakened when used for a long time.

이를 개선한 종래기술로 한국등록특허 제10-1843422호(2018.03.23.)에는 '발포폴리프로필렌을 이용한 부표 및 그 제조 방법'이 개시되었다.Korean Patent Registration No. 10-1843422 (2018.03.23.), as a conventional technology that has improved this, discloses a'buoy using foamed polypropylene and a method for manufacturing the same.'

상기 인서트부의 밀도는 상기 본체부의 밀도보다 낮게 형성되고, 상기 인서트부와 본체부가 고온건조되는 과정에서 상기 인서트부의 팽창력이 상기 본체부의 팽창력보다 높아 상기 인서트부와 본체부가 밀착됨으로써 결합되는 것을 특징으로 한다.The insert portion is formed to have a density lower than that of the body portion, and the insert portion and the body portion have an expansion force higher than the expansion force of the body portion in a process of drying the insert portion and the body portion at a high temperature, and the insert portion and the body portion are in close contact with each other. .

다만, 상기한 기술은 발포폴리프로필렌(EPP)으로 이루어짐으로써, 기본적으로 폴리프로필렌의 성질을 가져 내열성이 우수하고 약품성이 강하여 친환경적이나, 폴리프로필렌의 가격이 고가인 문제점이 있었다.However, since the above-described technology is made of expanded polypropylene (EPP), it is basically eco-friendly because it has the properties of polypropylene and has excellent heat resistance and strong chemical properties, but there is a problem that the price of polypropylene is expensive.
