Abstract
The objective of this study was to investigate the effect of cure type on the processing and physical properties under conditions of similar stress-strain properties. On the carbon black filled natural rubber(NR) based compound, the induction time decreased, but the cure rate became fast with increasing loading of sulfur donor agent. Tensile strength was little affected on the curing type. However, elongation generally decreased with increasing accelerator. Effect of cure type on the blow-out properties was followings: CV
대표적 가교형태 변화에 따른 유사한 stress-strain 특성을 나타내는 조건하에서 공정특성 및 전반적 물성에 미치는 영향을 조사하였다. 천연고무 기본 배합에서 촉진제나 황 공여체(sulfur donor) 증가에 따라 induction time은 길어지나, 가류속도는 빨라졌다. 가교계 변화에 따른 인장강도의 영향은 매우 적은 반면 신장율은 conventional vulcanization(CV)계에서 efficient vulcanization(EV)계로 갈수록 감소하는 경향을 보여 주었다. Blow-out이 발생하는 시간을 가교형태에 따라 비교하여 보면 CV

Keywords: cross-linking types; hybrid cure; conventional vulcanization(CV); efficient vulcanization(EV); NR
