Abstract
Effects of coating materials of steel cord, compounding ingredients, service history, and aging methods on the adhesion between steel cord and rubber compound were investigated for four different test tires, which were manufactured using the brass(Cu/Zn) coated steel cords, the ternary alloy(Cu/Zn/Ni) coated steel cords, and the compounding rubbers with different amounts of sulfur and cobalt salt respectively. The main effect and the mutual interaction of each factor were investigated by the analysis of variance for the test results. Initial adhesion was not affected by cure conditions. However, the adhesion after aging was found to be affected clearly. Analysis of adhesion after tire services or aging processes showed that good adhesion was obtained for the ternary alloy coated steel cords, and the degradation rate of adhesion was increased by the compound containing cobalt salt. Experimental data of adhesion for test tires were in accord with the results obtained using TCAT test method.

황동(Cu/Zn) 또는 삼성분 합금(Cu/Zn/Ni)이 피복된 강선코드와 황과 코발트염 함량이 다른 배합고무로 네 종류의 시험타이어를 제작하여, 강선코드의 피복물질, 배합조성, 주행이력, 노화처리가 접착에 미치는 영향을 조사하였다. 시험 결과를 분산분석하여 각 인자의 주효과와 교호작용을 검토하였다. 가황조건이 달라도 접착초기에는 의미있는 차이가 없었으나, 노화 후 접착상태는 가황조건에 따라 차이가 있었다. 주행이나 노화 후 접착상태는 삼성분 합금이 피복된 강선코드에서 우수하였고, 코발트 염이 들어있는 배합고무에서 접착 노화가 심하였다. 시험타이어에서 조사된 접착 시험 결과는 TCAT 방법으로 얻어진 시험 결과와 같은 경향을 보여주었다.
