Abstract
Interfacial failure between NBR and other reinforced rubber strip easily occurred under stress and vibration for long time, as the poor compatibility of NBR with other different rubber results in a low peel adhesion force. In this paper, adhesion properties of NBR and other different rubber strip such as NR, SBR, BR and EPDM were studied. Also, peel adhesion force of NBR/NR blend with NBR compound was investigated to compare with that of NBR/SBR blend. The objectives of this study were to find a proper reinforced rubber strip having a good resistance of interlayer failure with NBR under harsh condition. T-Peel Test results showed that peel adhesion force between NBR and SBR was stronger than that of NR bonding with NBR, even if they had poor peel force. In the case of NBR blends, peel force of NBR/SBR blend was higher than that of NBR/NR blend with NBR strip. Especially, 40% NBR content in NBR/SBR blend exhibited very good suit for a reinforcing rubber strip bonding with NBR.

NBR은 다른 고무들과 상용성이 나쁘기 때문에 층간 접착력이 낮으며, 장기간 동안 응역과 진동에 노출되면 NBR과 보강고부 층 사이의 계면에서 파괴가 쉽게 발생하게 된다. 이런 현상을 알아보고자 본 논문에서는 NBR과 NR을 포함한 SBR, BR, EPDM 등과 같은 다른 고무층간의 접착특성을 조사하였으며, 더불어 NBR/NR 혼합고무와 NBR의 층간 접착력을 NBR/SBR 혼합고무와 비교하여 연구를 진행하였다. 본 연구의 목적으로는 가혹한 조건하에서 NBR과 다른 고무층이 접착할 때, 계면파괴 저항이 우수한 보강 고무층을 찾는 것이다. T-Peel Test 결과에 따르면, NBR과 층간 접착에 있어서 비록 낮은 접착력을 갖지만 SBR이 NR보다 강한 접착력을 보인다. NBR 혼합고무의 경우는 NBR/SBR 혼합고무가 NBR과의 층간 접착에 있어서 NBR/NR 혼합고무보다 높은 접착력을 나타낸다. 특히, NBR을 40% 함유한 NBR/SBR 혼합고무가 NBR 고무와의 층간 접착에 가장 우수한 보강 고무층임을 알 수 있었다.
