▎ 摘　　要

NOVELTY - Composite particles comprise 60-99.9 wt.% silica, and 0.1-40 wt.% graphene carbon. USE - The composite particles are useful for forming elastomeric formulation used in tire components such as vehicle tire treads, subtreads, tire carcasses, tire sidewalls, tire belt wedge, tire beads, and tire wire skim coats, wires and cable jacketing, hoses, gaskets and seals, industrial and automotive drive-belts, engine mounts, V-belts, conveyor belts, roller coatings, shoe sole materials, packing rings and damping elements. ADVANTAGE - The composite particles improves traction and stiffiiess. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for mating silica-graphenic carbon composite particles, involving drying a slurry comprising silica particles, graphene carbon particles and a liquid carrier to produce the composite particles; (2) an elastomeric formulation comprising a base elastomer composition and 5-70 wt.% silica-graphenic carbon composite particles; and (3) a method for making an elastomeric formulation, involving mixing silica-graphenic carbon composite particles with the base elastomer composition, and curing the mixture.
