This invention relates to the field of plastics technology, specifically to a conductive plastic particle and its preparation method.
The composition, by weight parts, consists of the following components: 70-76 parts polyvinyl chloride, 10-20 parts conductive carbon black, 10-16 parts graphite, 10-12 parts surfactant, 7-10 parts dispersant, 6-8 parts toughening agent, 15-20 parts conductive particles, and 8-12 parts reinforcing agent.
The specific steps are as follows: conductive carbon black, graphite, and conductive particles are mixed uniformly in a mixer to obtain a conductive filler; the conductive filler, surfactant, dispersant, toughening agent, and reinforcing agent are added to molten polyvinyl chloride, and then extruded using a twin-screw extruder.
In this invention, the conductive particles, conductive carbon black, and graphite are uniformly dispersed, enhancing the conductivity between the conductive fillers and resulting in a stable bond between the conductive fillers, forming conductive particles with a high bulk density.
This does not affect the operation of the production equipment or the conductive properties of the conductive polymer composite material.
