석유계 바인더 피치의 β-resin이 탄소블럭의 밀도에 미치는 영향 = Effect of β-Resin of Petroleum-based Binder Pitch on Density of Carbon Block

국문 초록 (Abstract)

석유 잔사유로부터 제조된 β-resin 함량이 각각 다른 바인더 피치와 등방코크스를 혼합 후 압축성형을 거쳐 탄소블럭을 제조하였다. 원소분석, FT-IR 및 열중량 분석을 통하여 바인더 피치의 물리적, 화학적 특성 및 열적 거동을 각각 고찰하였다. 또한, 주사전자현미경을 이용하여 측정된 탄소블럭의 파단면으로부터 등방코크스 입자와 바인더 피치의 결합성을 평가하였다. 실험 결과로부터 바인더 피치의 β-resin 함량이 높을수록 코크스와 바인더의 결합성이 향상됨을 알 수 있었다. 또한, 탄소블럭의 탄화 후 밀도는 β-resin 함량이 1.4%에서 20.1%로 증가함으로 인하여 1.325 g/cm3 에서 1.383 g/cm³으로 증가하였다.

다국어 초록 (Multilingual Abstract)

Carbon blocks were prepared by compression molding process using the mixture of isotropic cokes and binder pitches, which were reformed with different β-resin contents from pyrolysis fuel oil. Physical and chemical properties and also thermal behavior of binder pitches were investigated through elemental analysis, FT-IR and thermogravimetric analysis, respectively. The adhesion of binder pitches to isotropic coke particles was evaluated from SEM images of the fracture surface of carbon blocks. From these results, it is shown that the adhesion between the cokes and binder was enhanced by increasing the β -resin content of binder pitches. The density of the carbon block after carbonization also increased from 1.325 to 1.383 g/cm³ by increasing the β-resin content of binder pitches from 1.4 to 20.1%.
