Problems solved by technology

If the amount added is large, the color and quality of the product will be limited. For example, carbon black filled PP conducts electricity, and the conductivity does not change significantly until the filling percentage reaches 15%, and the surface resistance reaches the lowest value of 10 when the filling percentage reaches 30%. 3 Ω, at this time, the color of the material can no longer meet various and aesthetic requirements

Abstract

The invention discloses an application method of carbon black in the master batch of a conductive fiber, which comprises the following steps: carrying out surface modification on the carbon black, kneading the carbon black with other raw materials for preparing the master batch and granulating to obtain the master batch, and the method for surface modification of the carbon black comprises the steps of atomizing the coupling agent for superconductive carbon black and spraying on the surface of the carbon black for modifying. The master batch of the garment conductive fiber prepared from the modified superconductive carbon black of the invention comprises the following components in mass percent: 44.5% of carrier resin, 12% of composite modified resin, 35% of modified superconductive nano carbon black, 3.5% of lubricant, 1.0% of antioxidant and 4.0% of dispersant. By modifying the superconductive carbon black, compared with the traditional carbon black, the conductivity is improved by more than one time, and the prepared conductive master batch has the advantage of preparing various conductive fibers.

Description

technical field [0001] The invention relates to an application method of carbon black as a conductive agent in a conductive fiber masterbatch, and provides a clothing conductive fiber masterbatch using the modified conductive agent carbon black as a conductive agent. Background technique [0002] Everyday people's clothing is prone to static electricity due to friction and collision phenomena, and there is often a "popping" discharge sound. If this phenomenon is not eliminated in time in certain occasions, such as coal mines, electronics, printing, packaging, etc., it is easy to cause static electricity accidents, which has become one of the major hidden dangers of safety production in the above-mentioned fields. The main methods to prevent static electricity on the surface of polymers are: air ionization method, humidification method, metal contact discharge method, radiation method, conductive substance introduction method, surface moisture absorption film method, chemical...
