Conducive polyacrylonitrile fiber and preparation method thereof

Abstract

The invention discloses conducive polyacrylonitrile fiber, which is prepared from the following raw materials in parts by weight: 110 to 130 parts of acrylonitrile, 4 to 6 parts of dibenzoyl peroxide,2 to 3 parts of acetylene black, 17 to 20 parts of alkenyl succinic anhydride, 0.1 to 0.2 part of polysorbate, 0.7 to 1 part of calcium stearate, 0.4 to 1 part of diphenyl imidazoline, 3 to 4 parts of pentaerythritol and 0.5 to 0.6 part of ammonium persulfate. The acrylonitrile is used as monomers to be polymerized under the effect of initiators, so that the carbon black doped polyacrylonitrile is obtained. The conduction performance of the finished product fiber can be effectively improved; the toughening effect is also achieved.

Description

technical field [0001] The invention belongs to the field of fibers, and in particular relates to a conductive polyacrylonitrile fiber and a preparation method thereof. Background technique [0002] According to the conductive components, there are four main types of conductive fibers: metal fibers, carbon black fibers, conductive metal compound fibers and conductive polymer fibers. Metal fibers have good electrical conductivity, heat resistance, and chemical corrosion resistance. However, for textiles, metal fibers have small cohesion, poor spinning performance, and limited finished color. They are mostly used in carpets and work clothes fabrics. expensive. Carbon black fiber is a conductive fiber made by mixing carbon black with fiber-forming substances and using sheath-core spinning method. In addition to maintaining the original mechanical properties of the fiber, it also obtains certain electrical conductivity, but the color is single, usually black. Or gray and black...

AI Technical Summary

Problems solved by technology

Based on ordinary fiber, the fiber surface is coated with carbon black by coating method, the carbon black is easy to fall off, the hand feel is not good, and the carbon black is not easy to distribute evenly on the fiber surface

Conductive metal compound fiber, with sulfide, iodide or oxide of copper, silver, nickel and cadmium as conductive material, made by mixed spinning method, adsorption method or chemical reaction method, with good fastness, among which copper, silver The compound also has certain additional functions, such as antibacterial and deodorizing, but the cost of silver is high, while the conductive fibers of copper, nickel and cadmium sulfide and iodide are worse than carbon black fibers, and the electromagnetic shielding performance is average. antistatic
