황동이 피복된 코드의 표면 상태가 배합고무와 코드의 접착에 미치는 영향
The Effect of Surface State of Brass Coated Steel Cord on the Adhesion between Cord and Rubber Compound
초록
80℃에서 열처리하거나, 80℃와 상대습도 85%인 습도 조건에서 처리한 황동이 피복된 강선 코드의 표면 상태와 고무와 접착 성질을 조사하였다. 열처리로 황동의 산화가 진행되었으며, 습윤처리 후에는 더 심하게 산화되었다. 처리기간이 길어질수록 전처리한 코드의 접착 성질이 나빠졌으며, 고무부착 정도가 심하게 저하되었다. 황동 피복층의 산화로 인한 코드의 접착 성질 저하를 산화아연층의 과도한 성장과 연계지어 설명하였다.
Adhesion between cord and rubber compound of brass plated steel cords pretreated at 80℃ in air and at 80℃ and 85% of relative humidity was studied. Surface change of brass with pretreatment was also studied. Brass was oxidized at thermal treatment and oxidation was accelerated with water at humid treatment. Adhesion of pretreated cords decreased with treatment period. The decreasing tendency of rubber coverage was severe. Decrease in adhesion properties due to brass oxidation was discussed relating to the overgrowth of zinc oxide layer.
