  • Rubber compositions with filler and ketoxime or ketoximo silane
    Patent number: 9725580
    Abstract: A composition includes an elastomer and a ketoximo silane or a ketoxime additive.
    Type: Grant
    Filed: September 23, 2015
    Date of Patent: August 8, 2017
    Assignee: Bridgestone Corporation
    Inventors: Chenchy J. Lin, Yaohong Chen, Atsushi Fukushima, William L. Hergenrother, Terrence E. Hogan
  • COMPOUNDING SILICA-REINFORCED RUBBER WITH LOW VOLATILE ORGANIC COMPOUND (VOC) EMISSION
    Publication number: 20160347777
    Abstract: Alkoxy-modified silsesquioxane compounds are described. The alkoxy-modified silsesquioxane compounds contain an alkoxysilane group that participates in an alkoxysilane-silica reaction as a silica dispersing agent in rubber, with the release of zero to about 0.1% by weight of the rubber of volatile organic compounds (VOC), especially alcohol, during compounding and further processing. Further described are methods for making alkoxy-modified silsesquioxanes, methods for making vulcanizable rubber compounds containing alkoxy-modified silsesquioxanes, vulcanizable rubber compounds containing alkoxy-modified silsesquioxanes, and pneumatic tires comprising a component that contains alkoxy-modified silsesquioxanes.

  • Rubber composition with improved bis-silane reinforcement
    Patent number: 9018290
    Abstract: The present disclosure is directed to tire rubber compositions containing at least one rubbery polymer (with 10 to 100 weight percent of monomer units derived from conjugated diene monomer having between 4 and 8 carbon atoms and 0 to 90 weight percent of monomer units derived from vinyl aromatic monomer); 0.5 to 100 phr of silica filler; 0.05 to 20 phr of a bi-functional silica coupling agent; and 1 to 30 phr of a non-elastomer reactive filler reinforcing agent capable of interacting with at least two silica particles. The bi-functional silica coupling agent and the filler reinforcing agent are utilized in a weight ratio of from 1:100 to 1:0.2. Also disclosed are methods for preparing the tire rubber compositions.

  • Rubber compositions containing non-sulfur silica coupling agents bound to diene rubbers
    Patent number: 8597790
    Abstract: The invention provides vulcanizable rubber compound having improved tensile mechanical and dynamic viscoelastic properties. The compounds are formed by mixing an elastomer, containing unsaturated carbon-carbon bonds in its molecular structure, with a reinforcing inorganic filler silica in the presence of an alkyl alkoxysilane and a non-sulfur coupling agent that binds to the rubber backbone with an “ene” linkage or a 1,3 dipolar addition linkage. In particular, the coupling agent and the alkyl alkoxysilane are present in the compound in a weight ratio of about 0.0001:1 to about 1:1.
