摘　　要：研究夹持方式和钢丝帘线埋入长度对橡胶-钢丝帘线粘合性能测试结果的影响。结果表明:采用槽式结构夹具可以消除夹紧力对橡胶-钢丝帘线抽出力测试结果的影响;随着钢丝帘线埋入基体橡胶长度的增大,静态抽出力和最大伸长量均增大,但单位长度粘合强度随之呈指数衰减;橡胶-钢丝帘线的粘合存在摩擦力,钢丝帘线埋入橡胶长度越大,粘合失效到完全粘合失效经历的时间越长。The influence of clamping method and embedded length of steel cord on the measuring results of adhesion between rubber and steel cord was investigated.The results showed that,the impact of the clamping force on the measuring result of the pull out force of rubber-steel cord could be eliminated by adopting fixture with groove structure.Both the static pull out force and maximum elongation increased with the increasing of embedded length of steel cord,but the adhesion strength per unit length decayed exponentially.Friction force existed in the interface of rubber and steel cord,and the longer the length of steel cord embedded in rubber was,the longer time it took from initial adhesion failure to ultimate adhesion failure.
