▎ 摘  要

NOVELTY - Compound comprises: a fluoroelastomer material; and a filler material, where the filler material comprises a graphene-based carbon material comprising carbon particles comprising graphene comprising up to 15 layers, and particles of a nano-mix additive, where the particles of the nano-mix additive are integrated with the carbon particles on a particle level so that the particles of the nano-mix additive and the carbon particles form aggregates together. USE - The compound is useful for aerospace applications, high temperature applications or low temperature applications (claimed). ADVANTAGE - The compound: exhibits Phillips dispersion rating of the compound of 6-10, a G' storage modulus at -20 degrees C as measured by ASTM D5992-96 (2011) of 5-12 MPa, a tan delta at -10 degrees C as measured by ASTM D5992-96 (2011) of 0.35-1, a tan delta at 0 degrees C as measured by ASTM D5992-96 (2011) of 0.3-0.6, a tan delta at 30 degrees C as measured by ASTM D5992-96 (2011) of 0.1-0.3, a G' storage modulus at 30 degrees C as measured by ASTM D5992-96 (2011) of 1-6 MPa, a J'' loss compliance at 30 degrees C as measured by ASTM D5992-96 (2011) of 4E-8 1/Pa to 1E-7 1/Pa, a tan delta at 60 degrees C of ASTM D5992-96 (2011) of 0.1-0.3, and a G' storage modulus at 60 degrees C as measured by ASTM D5992-96 (2011) of 1-4 MPa (claimed); utilizes the carbon materials that provide tuning of the properties of reinforced elastomers and influences the processing and/or properties of elastomers containing these materials; provide desired physical properties of the finished elastomer and environmental benefits of not pelletizing the carbon e.g. reducing the quantity of water and energy required in the carbon production processes; and utilizes the graphene-based carbon materials that exhibit improved purity, lower volatile organic compounds, lower concentration of residual hydrocarbons (e.g. polycyclic aromatic hydrocarbons), and is safer to handle and more environmentally friendly as compared to carbon black.
