Description

technical field [0001] The invention belongs to a preparation method of polyethylene / ethylene propylene rubber / carbon black polymer conductive composite material. Background technique [0002] With the rapid development of electronic technology and the popularization of electronic products, the demand for conductive polymer materials is increasing day by day, and the application range is expanding. According to the different nature of conductivity, conductive polymer materials can be divided into two types: structural type (or called intrinsic type) and composite type. Structural conductive polymer materials have their own conductive function, such as polyaniline, polyacetylene, polypyrrole, etc. However, this type of conductive polymer material has not been popularized so far due to many difficulties in mass production and application. The composite conductive polymer material uses the method of mechanical blending to endow the material with conductive fillers such as met...
