Abstract
The adhesion phenomena of the interfaces between metal plates (Ni, Cr, Brass) and a rubber(polyisobutylene-co-isoprene), containing sulfur as a vulcanizer, was investigated in this work. The effect of sulfur on the interfacial phenomena was examined by measuring the adhesion forces. No effect on Cr-plate was observed. In the case of Ni and Brass plates, there are some differences in reactivity. The adhesive energy, Ga, was calculated from the results of 180°peel test, and the adhesive energy was found to be dependent on the reactivity of sulfur and metals and the viscoelastic property of the rubber. When the chemical bond across the interfaces was estabilished, cohesive failure was observed and the mechanical property of the corroded layer seemed to play an important role in adhesion. It was also found that the adhesive energy of the metal/rubber interfaces showed about one order lower than the tear energy of the pure rubber.

금속판(Ni, Cr, Brass)과 가황된 고무 (polyisobutylene-co-isoprene) 계면에서의 접착현상을 조사하였다. 황의 계면에서의 영향을 접착력을 측정하여 조사하였으며 Ni과 Brass인 경우 반응성은 다르나 황과의 반응이 있었고 Cr에서는 황과의 반응이 없었다. 접착에너지, Ga, 는 180°peel시험 결과로부터 계산하였고 황과 금속의 반응성과 고무의 점탄성에 관계됨을 알았다. 계면에 화학결합이 형성될 때 cohesive 파괴가 일어났으며 생성된 부식층의 기계적 성질은 접착에 큰 영향을 미침을 알았다. 금속/고무계면의 접착에너지는 순수한 고무의 tear 에너지값보다 약 1/10 낮음을 또한 알았다.
