The invention discloses a cobalt-containing composite coating for a steel cord and a preparation method of the cobalt-containing composite coating. The specific preparation method comprises the following steps that 1, a coating production technology principal conducts preparation scheme review and puts forward questions and answers, technicians compile special preparation schemes and pay attention to details, and technical disclosure is conducted to workers; secondly, a sand bag grinding tool is used for conducting overall rough grinding and surface accurate grinding treatment on the steel cord steel wire base body; thirdly, the steel cord steel wire base body is cut into sections through a hydraulic clamp; polishing scum on the surface is purged through high-pressure gas; according to the cobalt-containing composite coating for the steel cord and the preparation method of the cobalt-containing composite coating, rare earth is added, the coating structure is refined, and the atomic activity is improved; the initial bonding performance of the Cu-Zn-Co coating and rubber is improved, meanwhile, more excellent aging bonding performance and damp-heat aging bonding performance can be achieved, and the possibility of industrial application of the cobalt-free sizing material is increased.

    本发明公开了一种钢帘线用含钴复合镀层及其制备方法,具体制备方法步骤如下:步骤一:镀层生产技术负责人进行制备方案会审,提出疑问并解答,技术人员编制专项制备方案和注意细节,并且向工作人员进行技术交底;步骤二:利用砂袋修磨工具对钢帘线钢丝基体进行整体粗磨和表面精磨处理;步骤三:利用液压钳将钢帘线钢丝基体剪切成段;并且通过高压气体对表面的打磨浮渣进行吹扫;该钢帘线用含钴复合镀层及其制备方法,添加稀土,细化镀层组织,增加原子活性;增加Cu‑Zn‑Co镀层与橡胶的初始粘合性能,同样还能有更优越的老化粘合与湿热老化粘合性能,增加了无钴胶料在工业应用的可能性。
