Preparation method of electromagnetic shielding conductive fabric

Abstract

The invention discloses a preparation method of an electromagnetic shielding conductive fabric. In the preparation method, the electromagnetic shielding conductive fabric is prepared by sequentially carrying out pretreating, vacuum nickel plating, copper electroplating and nickel electroplating on a full polyester fabric, and then the obtained electromagnetic shielding conductive fabric is cured, wherein plasma glow discharge treatment is carried out in the pretreating step, a magnetron sputtering technology is adopted in the vacuum nickel plating step, and a vertical placement mode is adopted among conductive rods in the processes of copper electroplating and nickel electroplating. By adopting the technology combining the vacuum nickel plating with the copper electroplating and the nickel electroplating, the defects of high cost and difficult treatment of electroplating wastewater, caused by the adoption of an electroless copper and nickel plating technology in the traditional preparation method of the electromagnetic shielding conductive fabric, are avoided; and compared with the traditional preparation method of the electromagnetic shielding conductive fabric, which adopts a full vacuum copper and nickel plating technology, the method of the invention which adopts the technology combining the vacuum nickel plating with the copper electroplating and the nickel electroplating has smaller equipment investment and plating resistance, is more suitable for large-scale production, and can better adapt to market demands.

Description

technical field [0001] The invention relates to an improvement of a preparation method of an electromagnetic shielding conductive cloth. Background technique [0002] With the development of modern science and technology and the continuous improvement of people's living standards, high-tech electrical products are becoming more and more popular.

Problems solved by technology

[0003] At present, there are two kinds of processes for preparing electromagnetic shielding conductive cloth. One is the electroless copper plating and nickel plating process. Although the product quality is high, it is difficult to meet the market requirements due to the high production cost of consumables and the difficulty in the treatment of electroplating wastewater; the other is The full vacuum copper plating and nickel plating process is difficult to mass produce and adapt to the market due to its large equipment investment and high plating resistance
