  • Tire rubber composition
    Patent number: 11413905
    Abstract: The present technology provides a tire rubber composition formed by blending a microparticle composite, which is formed from a solid component of a mixture containing an emulsion of an organic microparticle and a rubber latex, in a sulfur vulcanizable rubber; the emulsion of the organic microparticle being an emulsion containing a microparticle obtained by polymerizing and/or crosslinking at least one selected from the group consisting of polymerizable monomers, and oligomers, prepolymers, and polymers having a reactive functional group and having a molecular weight from 500 to 50000 simultaneously or stepwise in water; and an average particle size of the microparticle being from 0.001 to 100 ?m.
    Type: Grant
    Filed: May 18, 2017
    Date of Patent: August 16, 2022
    Assignee: The Yokohama Rubber Co., LTD.
