Abstract

Glass fiber-reinforced polyurethane foam used as a cold insulation for liquefied natural gas carriers requires excellent insulation and mechanical performance. In this study, the effect of the silane coupling agent according to the functional group was investigated to improve the mechanical properties of the glass fiber-reinforced polyurethane foam. As a result of the study, coupling agents with epoxy, amino, and mercapto functional groups showed excellent mechanical strength. This was confirmed to be due to the interfacial adhesion and additional cross-linking effects of glass fibers and polyurethane foam by differential scanning calorimetry (DSC) and scanning electron microscopy (SEM).


액화천연가스 운반선의 보냉제로 사용되는 유리섬유 강화 폴리우레탄 폼은 매우 우수한 단열성과 기계적 성능이 요구된다. 본 연구에서는 유리섬유 강화 폴리우레탄 폼의 기계적 물성을 향상시키기 위해 다양한 작용기를 갖는 실란 커플링제를 사용하여 작용기에 따른 유리섬유 강화 폴리우레탄 폼의 기계적 물성 변화를 고찰하였다. 연구 결과, 사용된 커플링제 중 epoxy, amino, mercapto 작용기를 갖는 커플링제가 우수한 기계적 강도를 나타냈다. 이는 실란으로 인해 형성되는 추가적인 가교결합과 유리섬유와 폴리우레탄 폼 간의 계면 접착력 향상으로 인한 것임을 differential scanning calorimetry(DSC)와 scanning electron microscopy(SEM)을 이용하여 확인하였다.
