▎ 摘  要

NOVELTY - Formulation comprises an elastomer material and a filler material including a graphene-based carbon material comprising nano-mix additive particles integrated with carbon particles on a particle level. The nano-mix additive particles form at least one aggregate with at least some of the carbon particles. USE - The formulation is used as rubber materials for dynamic and static systems, particularly in tires for various industries, such as tires for automotive, aerospace, other aircraft, passenger tires, off road equipment, earth mover type vehicles, and racing tires. ADVANTAGE - The graphene based carbon materials can be directly incorporated into the elastomer material without changing the carbon material. The materials do not need to be pelletized or compressed in order to densify them for transportation, which reduces the amount of water and energy required in the carbon production processes. The carbon materials allow tuning of the properties of the elastomer, have improved purity compared to carbon black, have lower volatile organic compounds (VOCs) than carbon black, do not result in residual oil on the surface of the elastomer and contain low concentrations of contaminants (e.g. ash, metals, and other elemental contaminants) compared to conventionally processed carbon black or graphene. The elastomeric compound has a faster rate of cure, improved elastic moduli, improved abrasion resistance and improved electrical conductivity.
