Beschreibung
Zusammenfassung:	The present invention relates to a thermosetting adhesive composition that enables the formation of an adhesive layer that exhibits improved impact peel strength in a wide temperature range including low temperatures and exhibits long-term reliability in environments exposed to high temperatures, high humidity and salt water, a structure including an adhesive layer formed using the same, and a method for manufacturing the same. The thermosetting adhesive composition includes: an epoxy resin; a silane-modified epoxy resin; a core-shell structured rubber copolymer including a core including a rubber polymer and a shell including a polymer cross-linked or graft-bonded to the core; a polyurethane resin including a polymer block derived from polytetrahydrofuran; and a thermal curing agent. 본 발명은 저온을 포함한 넓은 온도 범위에서 보다 향상된 충격 박리 강도를 나타내고, 고온, 고습 및 염수에 노출된 환경에서 장기 신뢰성을 나타내는 접착층의 형성을 가능케 하는 열 경화성 접착제 조성물과, 이를 사용하여 형성된 접착층을 포함한 구조체 및 이의 제조 방법에 관한 것이다. 상기 열 경화성 접착제 조성물은 에폭시 수지; 실란 변성 에폭시 수지; 고무 중합체를 포함한 코어와, 상기 코어에 가교 결합 또는 그라프트 결합된 중합체를 포함한 쉘을 포함하는 코어-쉘 구조의 고무 공중합체; 폴리테트라하이드로퓨란에서 유래한 고분자 블록을 포함한 폴리우레탄 수지; 및 열 경화제를 포함하는 것이다.
