Abstract

The present invention discloses a preparation method for an electricity conductive cloth and the electricity conductive cloth. The preparation method comprises the following steps: carrying out a catalytic treatment, wherein an ionic palladium solution is adopted to carry out a pretreatment on the surface of an original cloth; carrying out chemical copper plating, wherein chemical copper plating is performed on the surface of the original cloth; carrying out copper electroplating, wherein copper electroplating is performed on the original cloth, and a thickening treatment is performed on the copper layer of the original cloth; and carrying out nickel electroplating, wherein a nickel layer is electroplated on the surface to provide protection for the copper layer. With application of the method of the present invention to produce the electricity conductive cloth, equipment investment is less, and a copper electroplating layer is adopted to carry out thickening on the copper layer of the product, such that a cost of the copper electroplating process is less than a cost of a complete chemical copper plating process, and the resulting product has characteristics of low electric resistance, low internal stress of the plating layer, and good ductility so as to provide advantages of low cost, high yield, low electric resistance of the product, excellent adhesion and the like.

Description

technical field [0001] The invention relates to the field of conductive cloth, in particular to a method for preparing conductive cloth and the conductive cloth. Background technique [0002] In the existing preparation process of conductive cloth, it generally includes three steps of vacuum electroplating, copper electroplating and nickel electroplating. The specific process is to deposit a layer of metal on the surface of the cloth by vacuum electroplating. Thicken to achieve the required electrical conductivity, and finally a layer of nickel is electroplated to protect the copper layer after completion. However, the equipment investment of this preparation process is large, the production capacity is low, and the requirements on the surface of the raw material are high, and missing plating is prone to occur, resulting in low yield. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the above defici...
