Description

친환경 방음, 방염 샌드위치패널 및 이의 제조방법{Eco-friendly soundproofing, flame retardant sandwich panel and manufacturing method thereof}Eco-friendly soundproofing, flame retardant sandwich panel and manufacturing method thereof

본 발명은 재활용률이 낮고 폐기가 여의치 않고 환경오염을 유발하는 스티로폼을 사용할 필요가 없음은 물론 방수, 방음 및 방염효율이 매우 우수한 친환경 방음, 방염 샌드위치패널 및 이의 제조방법에 관한 것이다.The present invention relates to an eco-friendly soundproofing and flameproof sandwich panel that has a low recycling rate, is not easily disposed of, does not need to use Styrofoam that causes environmental pollution, and has excellent waterproofing, soundproofing and flameproofing efficiency, and a method for manufacturing the same.

일반적으로, 샌드위치 패널은 주로 조립식으로 건축물을 짓는 데 사용되는 건축용 패널이다.In general, a sandwich panel is a building panel mainly used to build buildings in prefabricated form.

이러한 샌드위치 패널은 제작이 간단하며, 단가가 낮으며 작업성이 좋아서, 창고, 조립 주택, 공장 건물 및 사무실 등에 많이 사용되고 있다.Such a sandwich panel is simple to manufacture, has a low unit cost, and has good workability, and is widely used in warehouses, assembly houses, factory buildings, and offices.

샌드위치 패널은 외벽을 구성하는 양면의 철판과 철판들 사이로 배치되는 단열재로 구성되며, 최근에는 화염의 접촉에 견딜 수 있으면서 단열재의 화염에 대한 노출을 차단하여 화염에 의한 착화시기를 늦출 수 있는 난연 샌드위치 패널이 국내공개특허공보 공개번호 제10-2018-0040200호로 제안된 바 있다.Sandwich panel is composed of steel plates on both sides constituting the outer wall and an insulating material disposed between the steel plates. Recently, a flame-retardant sandwich that can withstand the contact of a flame and delay the ignition timing by a flame by blocking the exposure of the insulating material to the flame A panel has been proposed as Korean Patent Laid-Open Publication No. 10-2018-0040200.

그러나, 상기 국내공개특허공보 공개번호 제10-2018-0040200호의 경우, 단열재로서 스티로폼을 사용하게 되는데, 이러한 스티로폼은1974년 국내에 처음 도입해 연간 2만5천톤 이상이 포장재 및 단열재 등으로 쓰이고 있다.However, in the case of the Korean Patent Laid-Open Publication No. 10-2018-0040200, Styrofoam is used as an insulating material. This Styrofoam was first introduced in Korea in 1974, and more than 25,000 tons per year are used as packaging materials and insulation materials. .

지금까지는 85%정도가 재활용됐지만 이런 상태가 계속되면 재활용률이 낮아질 가능성이 크다.So far, about 85% has been recycled, but if this condition continues, the recycling rate is highly likely to decrease.

재활용률이 10%만 떨어져도 매년 2천5백 톤의 스티로폼을 추가로 매립하거나 소각해야 하며, 매립되는 스티로폼은 수백년이 지나도 분해되지 않아 문제가 되면 재활용이 어려워 일반쓰레기로 버려지면 결국 무단소각이 일어나 대기오염으로 이어지는 문제점이 있다.Even if the recycling rate drops by 10%, an additional 2,500 tons of Styrofoam must be landfilled or incinerated every year. There is a problem that leads to contamination.
