Embodiment 1

[0049] In the first embodiment, the conductive plastic includes 5v% stainless steel fiber (SS), 93v% thermoplastic PC and 2v% processing aid. The stainless steel fiber (SS) is divided into long and short fibers. The long fiber has a diameter of 12um and a length of 10mm. The short fiber has a diameter of 6um and a length of 1mm. The mixed volume ratio of long fiber and short fiber is 10:1. , Long and short fibers present a three-dimensional network in the thermoplastic PC. The processing aid includes 1.0v% diisodecyl phthalate, 0.3v% aluminate, 0.2v% N,N-diphenyl-p-phenylenediamine, 0.4v% antimony trioxide, 0.1v% benzophenone.

[0050] The flat scanning electron microscope of the conductive plastic particles of this embodiment is such as figure 2 As shown, the cross-sectional scanning electron microscope of the conductive plastic particles of this embodiment is as image 3 As shown in the above two figures, it can be seen that the long and short stainless steel fibers (SS) are in...

Abstract

The present invention discloses one kind of conductive plastic and its processing method and apparatus. The conductive plastic includes conductive fiber 0.1-45 vol%, thermoplastic plastic 55-99 vol% and machining assistant 0-3 vol%. The conductive fiber is arranged in 3D netted form homogeneously with multiple joining points, and the conductive plastic has high conductivity, high antistatic and electromagnetic shielding effect, and low surface resistance and volumetric resistivity, and may be injected, extruded and molded like common plastic.

Description

Technical field [0001] The invention relates to a plastic and its processing method and processing device, in particular to a plastic shell product that can be widely used in various environments and requires high-performance electronic products and devices with antistatic and anti-electromagnetic interference effects. Conductive plastic containing conductive fibers arranged in a three-dimensional network and its processing method and processing device. Background technique [0002] In the era of rapid development of the electronics industry, with the increasing availability of electronic products and devices, static electricity and electromagnetic waves have become one of the main electronic (electromagnetic waves) pollution in people's living and working environments. Correspondingly, the protective functional materials necessary to eliminate static electricity and prevent electromagnetic wave pollution have become a new type of electronic material currently researched. Its str...
