Preparation method of ultra-high molecular weight polyethylene fiber conductive weftless cloth

Abstract

The invention relates to a preparation method of ultra-high molecular weight polyethylene fiber conductive weftless cloth. The preparation method comprises the following steps: mixing ultra-high molecular weight polyethylene resin and paraffin oil, swelling, spinning, stretching and drawing; dipping obtained ultra-high molecular weight polyethylene fibers into gum, curing to shape and carrying outcontinuous cross compounding to obtain the weftless cloth; placing obtained ultra-high molecular weight polyethylene fiber weftless fabric in acetone, ethyl alcohol and a deionized water solution insequence to be subjected to ultrasonic oscillation; etching the dried ultra-high molecular weight polyethylene fiber weftless cloth by using a plasma etching machine to ionize negative charges on thesurface of the ultra-high molecular weight polyethylene fiber weftless cloth; and alternately spraying a polymer solution with positive charges and an inorganic nano-material solution with the negative charges on the surface of the etched ultra-high molecular weight polyethylene fiber weftless fabric to obtain the ultra-high molecular weight polyethylene fiber conductive weftless fabric. Accordingto the preparation method, under the condition that the strength and modulus of the weftless cloth are not affected, the ultra-high molecular weight polyethylene fiber weftless cloth is endowed withconductivity.

Description

technical field [0001] The invention belongs to the technical field of ultra-high molecular weight polyethylene fibers, and in particular relates to a preparation method of ultra-high molecular weight polyethylene fiber conductive non-weft fabric. Background technique [0002] Ultra-high molecular weight polyethylene is non-conductive. To give it conductivity, we can start from two aspects. One is to use conductive materials (such as metal nanomaterials and carbon-based nanomaterials) and ultra-high molecular weight polyethylene resins in the spinning stage. Mixed spinning, the conductive ultra-high molecular weight polyethylene fiber prepared by this method has good electrical conductivity, but it will adversely affect the inherent properties of the fiber itself, such as strength and modulus; the second method is to construct on the surface of the fiber Conductive coating, the main disadvantage of this method is that the friction between the fiber and the steel buckle will ...
