Abstract: A surface modified and functionalized carbon black for use in a rubber compound suitable for tire tread compounds which can be described as a surface modified low hysteresis carbon black. The modified carbon black contains a chemical consisting of at least one amine group and at least one thiol group and/or di- and/or polysulfidic linkage. The surface modified low hysteresis carbon black in a representative rubber tire tread compound shows improved rolling resistance, improved wet traction, and improved or maintained abrasion resistance, being superior to compounds containing N234 carbon black or silica. The improved tire rolling resistance obtained by using a compound containing a surface modified low hysteresis carbon black is highly desirable for reduced CO2 emissions, reduced pollution, sustainability, and protection of the environment.

Abstract: Graphene is an allotrope or one of the several physical forms of carbon, other examples being graphite, fullerenes, and diamond. At the atomic level, it is in the form a sheet with a thickness nominally under 1.0 nanometer and up to 1 micron in diameter. Sheets of such dimensions when added to other composites facilitate increases in thermal and electrical conductivity and in the case of elastomer nanocomposites, improvements in hysteresis, compounding ingredient dispersion, aging resistance, and reductions in permeability. In the case of conveyor belt cover compounds, natural rubber based formulations are preferred due to high tensile strength, tear strength and damage resistance, and high resistance to abrasion. Graphene as a performance additive enables further improvement in these critical properties.
