- W2027392137 abstract "본 연구에서는 석유계 폴리올을 대체하기 위하여 식물성 천연유인 피마자유를 개질한 천연유 기반 폴리올(Castor Oil based Polyol, COP)을 사용하여 폴리우레탄 폼을 합성하였다. 접촉각과 표면장력실험을 통해 계면활성제에 따른 석유계 폴리올과 COP와의 상용성을 측정하였다. 최적의 COP 함량과 계면활성제(surfactant)를 찾기 위해 COP 함량을 0 wt%에서 80 wt%까지 변화시키고, 계면활성제 L-580K, DC-5950, BF-2470를 사용하여 폴리우레탄 폼을 합성한 결과 COP의 함량이 30wt%이고 계면활성제로 BF-2470을 사용하였을 때 가장 우수한 기계적 물성을 나타내었다. Polyurethane foams were synthesized by substituting a portion of petroleum base polyether polyol with castor oil-derived polyol(COP). Contact angle tester and surface tensionmeter were used to examine the compatibility of petroleum base polyether polyol and COP. To investigate the optimum content of COP and surfactant, the content of COP has been changed from 0 wt% to 80 wt%. From the results of polyurethane foams synthesized by surfactant L-580K, DC-5950 and BF-2470, the best mechanical properties was observed when the content of COP was 30wt% and surfactant BF-2470." @default.
