Abstract

The present invention discloses an electricity conductive cloth electroplating post-treatment method, which comprises the following steps: coating and drying through extruding, wherein an electricity conductive cloth is dip-coated in a yellowing resistance polyurethane slurry and extruded; carrying out drying curing shaping, wherein the electricity conductive cloth is subjected to drying curing shaping; and winding, wherein the electricity conductive cloth is subjected to winding packaging. The post-treatment method of the present invention has the following characteristics that: a process is simple, batch production is easily achieved, no wastewater is generated during the production process, and the method is an environment protection process. The electricity conductive cloth treated by the method of the present invention has advantages of strong metal adhesion, excellent wear resistance, yellowing resistance, good anti-fingerprint discoloration property, and the like.

Description

technical field [0001] The invention relates to the field of conductive cloth, in particular to a method for treating conductive cloth after electroplating. Background technique [0002] If the existing conductive cloth is not subjected to a surface post-treatment process after electroplating, the product will have problems such as being susceptible to corrosion, poor anti-fingerprint ability, and easily insufficient wear resistance. Some manufacturers will passivate the nickel layer after electroplating, which can improve the anti-fingerprint ability of the conductive cloth, but the wear resistance of the product is poor. Better, some manufacturers apply polyurethane adhesive layer to the conductive cloth after electroplating to improve the wear resistance and anti-fingerprint discoloration ability of the product, but in the existing process, after coating polyurethane adhesive layer treatment, it reduces Due to the flexibility of the conductive cloth, the product is prone...
