코발트 염의 첨가가 고무와 황동이 피복된 강선간의 접착에 미치는 영향
The Effect of Cobalt Salt on the Adhesion between Brass-Plated Steel Cord and Rubber Compound
초록
코발트 염의 첨가량을 달리하여 배합된 고무의 물성과 이 고무와 황동이 피복된 강선간의 접착특성을 조사하였다. 코발트 염의 첨가가 배합고무의 물성에 미치는 영향은 크지 않았으나, 접착특성은 코발트 염의 참가량과 열화처리에 다라 크게 달라졌다. 코발트 염의 함량이 적은 고무에서는 pullout force와 고무의 부착 정도로 나타내어지는 접착특성이 향상되었으나, 함량이 1.5phr이상인 고무에서는 열화 후 접착특성이 크게 나빠졌다. 코발트 염의 과량 첨가에 따른 접착특성의 저하를 접착층의 성장과 관련지어 설명하였다.
The effect of cobalt salt in rubber compound on the physical properties of the rubber compound and the adhesion properties between the rubber compound and brass-coated steel cord was studied. Although the change in the physical properties of the rubber compound with the addition of cobalt salt was small, the adhesion properties were changed significantly with the loading level of cobalt salt and aging treatments. Pullout force and rubber coverage of the steel cord were enhanced in the rubber compound with low loading of cobalt salt. When the loading level of cobalt salt was higher then 1.5phr, the adhesion was severely deteriorated after aging treatments. The easy failure in the adhe-sion of the sample with high loading of cobalt salt was explained in terms of the growth of the interfacial layer.
