초록

용액중합 스티렌-부타디엔 고무 컴파운드 가교체의 균열저항성 및 마모특성에 미치는 공정오일의 영향을 조사하기 위해 방향족 고리화합물(PCA) 성분을 다량 함유하고 있는 방향족 오일과 저 PCA 오일을 선택하였다. 인장강도 및 인열강도 결과에 의하면 방향족 오일함유 컴파운드가 저 PCA 오일함유 컴파운드에 비해 우수한 물성을 나타내었다. 또한 방향족 오일함유 컴파운드가 균열저항성이 월등히 우수하였고, 특히 인열에너지가 낮은 범위에서 더 우수한 결과를 나타내었다. 마모저항특성은 마찰에너지가 낮은 범위에서는 방향족 오일함유 컴파운드가 우수한 결과를 나타낸 반면, 높은 마찰에너지 범위에서는 저 PCA 오일 함유 컴파운드가 오히려 높은 저항성을 나타내었다.

Commercial grades of solution styrene-butadiene rubbers extended with high aromatic oils having high polycyclic aromatic compounds (PCA) and low PCA oils were used to study the effect of the processing oil particularly on the crack propagation resistance and frictional wear resistance of the vulcanizates. The aromatic oil based vulcanizates exhibited superior fracture behavior over the low PCA oil extended vulcanizates based on tensile and trouser tear tests. Compounds with aromatic oil showed superior crack propagation resistance compared with those containing low PCA oil, especially at the lower ranges of tearing energy. In terms of frictional wear resistance, the aromatic oil extended compounds showed superior performance particularly in the lower frictional work ($W_f$) range but in the higher $W_f$ range the low PCA oil extended vulcanizates performed better.
