Abstract:
본 발명은 강화 페놀 폼 보드에 관한 것이다. 이는 일정두께의 플레이트의 형태를 취하고 하니컴 구조를 갖는 하니컴 평판체와; 상기 하니컴 평판체의 일측면 또는 양측면에 접착 고정되는 페놀발포층을 포함하여 구성된 것을 특징으로 한다. 상기와 같이 이루어지는 본 발명의 강화 페놀 폼 보드는, 미리 완성되어 있는 부품을 조립하여 구성하는 방식이므로 제작과정이 간단함은 물론, 특히 내부의 하니컴평판체의 내부가 비어 있으므로 밀도가 낮으면서도 단열성능과 내화성이 우수하고, 또한 굴곡탄성률이 좋아 높은 강성이 요구되는 외단열 견축자재로 더욱 적합하다.
