Problems solved by technology

The main problems of the conductive filler dispersion and compounding method currently used are: the distribution of the conductive filler in the product is often uneven, so that the conductivity of the finished product is inconsistent; the bonding between the conductive filler and the matrix resin is generally relatively weak. Poor, especially when the conductive filler content is high
Due to the many limitations of this type of product after use, the above manufacturing method is rarely used at present.

Abstract

The super-low resistance high-polymer conductive granule provided by the invention is characterized in that the surface resistance of high polymer material can be less than or equal to 8.0 ohm / sq andthe volume resistance thereof is less than or equal to 0.5 ohm.cm by a special modified manufacturing process via adding nanoscale high-property conductive black and other accessory ingredients. The material is a high-property conductive plastic with even and stable electrical property, perpetual conductive function and small damaged mechanical property of product carrier material.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an ultra-low resistance polymer conductive pellet product and a preparation method thereof. Background technique [0002] The formation principle of the conductive function of high molecular polymers refers to taking certain measures to reduce the volume resistance and surface resistance of high molecular polymers, so that the electrostatic charge accumulated in the polymer itself can be released quickly, thus ensuring the variety of high molecular polymer materials. The adaptability of processing methods and the safety of product use. [0003] There are two main types of methods for the conductive modification of high molecular polymers. One type of structural conductive polymer material refers to the conductivity of the polymer itself or after chemical modification, and the other type is the compound type conductive polymer material. Polymer materials refer to the ad...
