초록
폴리프로필렌(polypropylene, PP)/케나프 섬유(kenaf fiber, KF) 펠트와 폴리우레탄(polyurethane, PU) 바인더의 계면 접착특성 향상을 위해 코로나 방전처리와 상용화제로 말레인산 무수물(maleic anhydride, MAH)이 그래프트된 PP-g-MAH가 적용되었다. PU 바인더의 반응온도와 시간 선정을 위해 DSC를 이용하여 등온 실험을 수행하였다. 코로나 방전처리와 상용화제 적용에 따른 PP/KF/PU 복합체의 기계적 물성 변화를 고찰하기 위해 인장, 굴곡 및 충격 특성을 평가하였다. 코로나 방전처리 및 PP-g-MAH 처리의 경우 인장특성과 충격특성이 개선되는 경향을 나타내었다. 기계적 물성의 증가는 코로나 방전처리 및 PP-g-MAH에 의한 PP의 산소기 도입으로 mPP/KF와 PU 바인더간의 상용성이 개선되었기 때문으로 해석할 수 있고, 파단면의 SEM 사진으로부터 확인되었다.
In order to improve the interfacial adhesion property between polypropylene (PP)/kenaf fiber (KF) felt and polyurethane (PU) binder, corona discharge treatment and PP-g-MAH grafted maleic anhydride (MAH) were applied as a compatibilizer to PP/KF felt. Isothermal experiments were carried out by using differential scanning calorimetry (DSC) to determine the reaction temperature and time for PU binder. Tensile, flexural and impact properties were evaluated to analyze the mechanical properties of PP/KF/PU treated by corona discharge and PP-g-MAH. In case of modified-PP (mPP)/KF/PU composite treated by corona discharge and PP-g-MAH, the tensile and impact properties were improved. It may be because when the corona discharge was applied to the mPP/KF felt, the compatibilizing ability between the mPP/KF and PU binder increased due to the insertion of oxygen group in PP chain. The interface adhesion properties of the mPP/KF/PU composites were identified by SEM images of the fracture after the tension test.
