摘　　要：为研究电镀钢丝镀层对帘线黏合和剥离性能的影响,分别生产不同镀层重量、镀层铜含量和镀层表层铜含量的Φ1.72 mm电镀黄铜钢丝,以相同工艺拉拔捻制为2×0.30 HT钢帘线,用以帘线和橡胶黏合和剥离性能测试。结果发现:当帘线镀层重量在2.47~4.34 g·kg^(-1)、镀层铜含量在61.30%~66.36%时,帘线和橡胶建立了良好的黏合强度和黏附效果,即帘线和橡胶在此范围具有较好的黏合和剥离性能,钢丝表层铜含量在57.82%~62.22%时,帘线与橡胶的黏合和剥离性能均良好,说明此范围内表层铜含量的变化未对帘线黏合和剥离性能造成明显的或不利的影响。同时,当钢丝铜含量或表层铜含量偏低,均使得拉拔损失增加,不利于钢丝拉拔。In order to study the effect of electroplating steel wire coating on the adhesion and peeling property of steel cord,the electroplating brass steel wire of 1.72 mm diameter was produced with different coating weight,copper content of coating and copper content of coating surface.The 2×0.30 HT steel cord was drawn and twisted with the same technology to test the adhesion and peeling property of steel cord and rubber.The study found that when the coating weight of steel cord was in 2.47‒4.34 g·kg^(-1),the copper content of the coating was in 61.30%‒66.36%,and the adhesion strength and adhesion effect of steel cord and rubber were well established.It also meant that the steel cord and rubber had better bonding and peeling property under these conditions.The adhesion and peeling property of steel cord and rubber was good when the copper content of steel wire coating surface was in 57.82%‒62.22%,indicating that the change of copper content of steel wire coating surface had no obvious or adverse effect on the adhesion and peeling property of steel cord.At the same time,when the copper percentage content or surface copper content was lower,the steel wire drawing loss increased,which was not conducive to steel wire drawing.
