Method for manufacturing silver-plated conductive fiber

Abstract

The invention provides a method for manufacturing a silver-plated conductive fiber. The method comprises the following steps of: a, performing plasma treatment on a fiber base material by using gas, and controlling discharge power of plasma to be 30 to 500W, vacuum air pressure to be 20 to 300 Pa, and the movement speed of the base material to be 0.5 to 50 m / min; b, placing the fiber base material which is subjected to plasma treatment in 20 to 500 g / L silver nitrate solution, and soaking for 5 to 60 minutes with stirring; c, performing plasma treatment on the fiber base material which is treated by the silver nitrate solution by using reduction gas, controlling the ion discharge power to be 30 to 500 W, vacuum air pressure to be 20 to 300 Pa and the movement speed of the base material to be 0.5 to 50 m / min, and reducing to form a silver-plated film; or controlling the movement speed of the fiber base material which is treated by the silver nitrate solution to be 0.5 to 50 m / min in a reduction gas furnace at the temperature of between 20 and 150 DEG C and under the air pressure of 20 to 300 Pa, and reducing to form the silver-plated film.

Description

Technical field: [0001] The invention relates to the technical fields of materials, microelectronics, electronics and electric engineering, in particular to a method for making silver-plated conductive fibers. Background technique: [0002] Silver has good thermal conductivity, electrical conductivity, chemical stability and ductility, and has the functions of sterilization and water purification. The silver layer is bright and uniform, and has good decoration. Therefore, it is widely used in electromagnetic shielding, medical equipment, and electronics industry. , decorative materials and other fields. [0003] At present, the production methods of silver-plated conductive fibers mainly include the following: 1) traditional electroplating method: this method needs to waste a lot of power resources and seriously pollutes the environment, and the fiber itself is not conductive, and it needs to be metallized 2) Vacuum magnetron sputtering method, this method has expensive equ...

AI Technical Summary

Problems solved by technology

Although this method avoids the waste liquid treatment problem of electroless plating, its own process is complicated and the operation is inconvenient.

Furthermore, this method cannot form a good metal coating, and the bonding force is weak

And the products obtained by the above method generally feel very poor, most of them cannot be cleaned, and cause environmental pollution etc. in production.
