Beschreibung
Zusammenfassung:	An embodiment of the present invention provides a sealant resin composition comprising: a first resin containing a copolymer composed of two or more compounds selected from the group consisting of ethylene, propylene, and butene; and a second resin containing an olefin block copolymer, wherein the weight ratio of the first resin and the second resin is 72 : 28 to 95 : 5. An embodiment of the present invention may provide an exterior material for a secondary battery, which enables sufficient sealing at low temperatures within a short time by including a sealant resin composition, is capable of enhancing an output by enabling the speed-up of a secondary battery production line, and minimizes thickness changes during sealing through sufficient heat resistance. 본 발명의 일 실시예는 에틸렌, 프로필렌, 및 부텐으로 이루어진 군으로부터 선택되는 2종 이상의 화합물로 이루어지는 공중합체를 포함하는 제 1 수지; 및 올레핀 블록 공중합체를 포함하는 제 2 수지를 포함하는 실란트 수지 조성물로서, 상기 제 1 수지 및 상기 제 2 수지의 중량비가 72 : 28 내지 95 : 5인 실란트 수지 조성물를 제공한다. 본 발명의 일 실시예에 따른 실란트 수지 조성물을 포함하여 저온 및 짧은 시간 내에 충분한 실링이 가능하고, 이차전지 제조 라인의 고속화가 가능하여 생산량을 향상시킬 수 있고, 충분한 내열성을 통해 실링시 두께 변화를 최소화하는 이차전지 외장재를 제공할 수 있다.
