본 발명은 액화가스 저장탱크용 2차 방벽으로서, 액화가스 저장탱크용 2차 방벽으로서, 폴리에틸렌, 폴리에틸렌테레프탈레이트, 폴리비닐알코올, 에틸렌비닐알코올 및 나일론으로 이루어진 군으로부터 선택되는 하나 이상의 고분자를 포함하는 차단층; 및 상기 차단층의 양면에 적층되는 섬유층을 포함하며, 상기 섬유층은 접착층에 의해 고정되는 것이다.
The present invention is a secondary barrier for a liquefied gas storage tank. The secondary barrier for a liquefied gas storage tank comprises: a barrier layer comprising at least one polymer selected from a group consisting of polyethylene, polyethylene terephthalate, polyvinyl alcohol, ethylene vinyl alcohol, and nylon; and a fiber layer laminated on both sides of the barrier layer, wherein the fiber layer is fixed by an adhesive layer. An object of the present invention is to provide the secondary barrier exhibiting excellent tensile strength and shear strength even in a cryogenic environment using the barrier layer containing a polymer that does not cause corrosion.
