초록

기존의 방열필름의 연소문제를 해결하기 위해 poly(tetra methylene glycol) (PTMG), 4,4’-methylenebis(phenyl isocyanate) (MDI)와 유기인이 도입된 실란 커플링제로 표면개질한 질화붕소를 사용하여 폴리우레탄과 개질된 질화붕소로 이루어 진 복합체를 제작하였다. Fourier transform-infrared (FT-IR) 분광 분석을 통해 질화붕소의 개질과 복합체의 합성 여부를 확인하였다. 또 universal testing machine (UTM) 측정을 통해 개질된 질화붕소의 함량에 따른 복합체의 기계적 물성변화를 확인하였으며, layser flash analysis (LFA)와 UL94 측정을 통해 열적 특성을 조사하였다. 그 결과, 복합체의 열전도도가 1.19 W/m.K로 증가하였으며, 자기소화성이 없어 타기 쉬운 폴리우레탄의 난연성이 UL94 V-1 등급으로 향상되었다.

Polyurethane/modified boron nitride (PU/m-BN) composite was synthesized from the poly(tetra methylene glycol) (PTMG), 4,4’-methylenebis(phenyl isocyanate) (MDI), and modified boron nitride (m-BN). The modification of boron nitride and synthesis of PU/m-BN composite were confirmed by Fourier transform infrared (FT-IR) spectroscopic analyses. The mechanical properties of the PU/m-BN composites were measured using the universal testing machine (UTM) and the thermal properties of the composites were investigated ser flash analysis (LFA) and UL94 measurements. As a result, the thermal conductivity of the polyurethane composite increased to 1.19 W/m.K, and the flame retardancy of the easy to burn polyurethane, which was not self-extinguishing was improved to UL94 V-1 grade.
