Abstract
A resin-rubber composite includes: a resin member that has a treated surface, to which a surface treatment by means of a plasma treatment has been applied; and a rubber member that is disposed in contact with the treated surface of the resin member and includes a rubber, a filler having a silanol group, and a silane coupling agent, with a filler content of from 30 phr to 100 phr with respect to 100 phr of the rubber, and a silane coupling agent content of from 2 parts by mass to 15 parts by mass with respect to 100 parts by mass of the filler.
Claims6
A tire, comprising a resin-rubber composite comprising:
- a resin member that has a treated surface, to which a surface treatment comprising a plasma treatment has been applied, the resin member comprising at least one resin selected from the group consisting of a thermoplastic polyester elastomer and a thermoplastic polyester resin;
- and
- a rubber member that is disposed in contact with the treated surface of the resin member and that comprises a rubber, silica as a filler having a silanol group, and a silane coupling agent, with a silica content of from 30 phr to 100 phr with respect to 100 phr of the rubber, and a silane coupling agent content of from 2 parts by mass to 14 parts by mass with respect to 100 parts by mass of the filler, the silica having a BET specific surface area of 150 m2/g to 400 m2/g, and the silane coupling agent being a polysulfide-based silane coupling agent having two or more sulfurs,
- wherein the silane coupling agent comprises at least one selected from the group consisting of bis-(3-triethoxysilyl) propyl)-disulfide, bis-(3-triethoxysilyl) propyl)-tetrasulfide, and bis-(triethoxysilylpropyl)-polysulfide.
