Antistatic biopolymers - side feeders for compressed biochar (Ast-BP)
Conventional industrial carbon black is applied in plastics processing as a functional additive in the form of conductive carbon black, colorant or as a filler, and accounts for the third largest filler market - and the trend is still increasing. However, industrial carbon black is mainly produced from aromatic-rich coal and petroleum-derived carbon black oils and is thus of fossil origin. A main objective of the research project is the development of an economical process for the production of electrically conductive, dust-reduced vegetable coal in order to produce sustainable biocomposites for Euro transport boxes with extension to the electrical industry.
The material to be developed is thus an electrically conductive thermoplastic biochar granulate. For the objective of electrical conductivity (antistatic properties), it must be ensured that the pyrolyzed particles are present in high numbers in mutual contact in the thermoplastic matrix in order to be able to form electrical current paths. In terms of process technology, the compression-minimized and vibration-supported addition of high proportions of conductive vegetable carbon via the side metering unit of the extruder is necessary.
