三相合金镀层钢丝在无钴橡胶中的粘合力研究

Study on Adhesive Force between Ternary Alloy Coated Steel Cord and Cobalt Free Tire Compound

研究铜、锌、钴三相合金镀层钢丝在无钴橡胶中的粘合性能,并与黄铜镀层钢丝在含钴胶料中的粘合性能进行对比。结果表明:在高温、高湿的老化条件下,三相合金镀层钢丝帘线的粘合力保持率明显提高,镀层中的钴可以抑制老化过程中脱锌的速度;橡胶中去除钴盐,使胶料的物理性能和抗裂纹扩展能力得到提升。

The adhesion property of steel cord with ternary alloy wire coating（TAWI）in cobalt free compound was investigated,and compared to the adhesion property of brass plated steel cord in cobalt containing compound.The results showed that,the adhesion retention of TAWI coated steel cord in cobalt free compound was higher after ageing at high temperature and high humidity.The cobalt in the coating could lower the dezincification rate.The physical properties and crack propagation resistance of the compound without cobalt were improved.
