Abstract

The invention relates to polymer / conductive filler / metal composite fiber. The composite fiber comprises polymer fiber containing metal short fiber and a conductive filler, the metal short fiber is dispersed in the polymer fiber as a dispersion phase and is in parallel distribution along the shaft of the polymer fiber; the conductive filler is dispersed in the polymer fiber and distributed among the metal short fiber; a metal is a low-melting-point metal, is at least one selected from single-composition metals and metal alloy, and has the melting point between 20 DEG C to 480 DEG C and lower than a polymer processing temperature; the volume ratio of the metal short fiber to the polymer fiber is 0.01:100-20:100; and the weight ratio of the conductive filler to the polymer is 0.1:100-30:100. By using the composite fiber, the volume resistivity is reduced, the wire fracture rate is reduced, and the surface of the fiber is smooth. The preparation method is simple, relatively low in production cost and easy for industrialized batch production.

Description

technical field

[0001] The invention relates to the field of synthetic fibers, and furthermore, the invention relates to a polymer / conductive filler / metal composite fiber and a preparation method thereof. Background technique

[0002] Compared with natural fibers, synthetic fibers have the characteristics of low price, low density and low moisture absorption rate, and are widely used in textiles and clothing, woven bags and other fields in daily production and life. However, synthetic fibers have good electrical insulation properties and high resistivity, and are prone to static electricity during use, which will bring harm to industrial production and people's lives. And with the development of high technology, static electricity and electrostatic adsorption of dust are one of the direct causes of modern electronic equipment failure, circuit short circuit, signal loss, bit error, and low yield. In petroleum, chemical industry, precision machinery, coal mine, food, medicine...
