초록

천연고무의 소련효과를 높이기 위하여 사용되는 소련촉진제가 천연고무 배합물의 점도나 Couette 보정치와 같은 유변학적 특성에 미치는 효과를 살펴 보았다. 소련촉진제로는 BAPS(Bis-(o-benzamido phenyl) disulfide), PCTP(Pentachlorothiophenol) 및 ADS(Aromatic disulfide)계의 것이 사용되었다. 실험결과 소련 촉진제의 사용에 따라 고무의 분자량이 감소하고 전단 점도도 감소하였다. Couette 보정치는 소련 촉진제의 사용량이 증가할수록 낮은 값을 나타냈으며 압출물의 팽창도 소련 촉진제를 사용하는 경우 감소하였다. 그러나 사용된 소련 촉진제들 간에는 큰 차이를 보이지 않았다.

The effects of peptizer, used to enhance the masticating efficiency, on the rheologiccal behavior of natural rubber compounds were investigated. BAPS(BIS(o-benzaamido phenyl) disulfide), PCTP(Penta-chloro-thiophenol) and ADS(Aromatic disulfide) were used as a masticating peptizer. Molecular weight and shear viscosity of the compounds were decreased with the addition of peptizing agents. The value of the Couette correction was decreased with increasing loading level of peptizer, and the extrudate swell was suppressed by the use of peptizer. However, little difference was observed between various peptizing agents used.

Keywords:Peptizer;natural rubber;couette correction;shear viscosity
