  • Modified fillers for rubber compounding and masterbatches derived therefrom
    Patent number: 10030124
    Abstract: A method for manufacturing a modified silica product includes admixing a mercapto silane and a silica to form a hydrophobated silica, and treating the hydrophobated silica with an oxidizing agent. Likewise, a method for manufacturing a silica masterbatch with the modified silica product includes the admixing a mercapto silane solution and a silica slurry to form a hydrophobated silica slurry, and then treating the hydrophobated silica slurry with an oxidizing agent to form a modified silica slurry. The modified silica slurry is blended with a rubber latex, which is then coagulated to form the silica masterbatch. Rubber formulations and articles manufactured with one of the modified silica product and the silica masterbatch are also disclosed.
    Type: Grant

    Date of Patent: July 24, 2018
    Assignee: Cooper Tire & Rubber Company
    Inventors: Howard Colvin, Peter John Wallen
  • Functionalized silica with elastomer binder
    Patent number: 9238729
    Abstract: A functionalized silica product includes particles of a hydrophobated silica having a coating of a polymer. A ratio of the hydrophobated silica to the polymer is from about 0.3/1 to about 100/1. The functionalized silica product may be in the form of a friable crumb or a powder, or in the form of a bale, that may be mixed into an elastomer formulation for a rubber article, such as a tire component.

  • Functionalized silica with elastomer binder
    Patent number: 9133325
    Abstract: A functionalized silica product includes particles of a hydrophobated silica having a thin coating of an emulsion polymer. A ratio of the hydrophobated silica to the emulsion polymer is from about 4/1 to about 50/1. The functionalized silica product is in the form of a friable crumb or a powder that may be mixed into a elastomer formulation for a rubber article, such as a tire component.
