Abstract
A rubber composition for a tire according to an embodiment of the present technology includes: 100 parts by mass of a diene rubber and from 1 to 30 parts by mass of a thermally expandable microcapsule composite body, and the thermally expandable microcapsule composite body contains one or more thermally expandable microcapsules and an acrylonitrile butadiene copolymer and/or a crosslinked body thereof covering the one or more thermally expandable microcapsules.
Claims13
A rubber composition for a tire, comprising:
- 100 parts by mass of a diene rubber;
- and
- from 1 to 30 parts by mass of a thermally expandable microcapsule composite body,
- the thermally expandable microcapsule composite body containing one or more thermally expandable microcapsules and an acrylonitrile butadiene copolymer and/or a crosslinked body of the acrylonitrile butadiene copolymer covering the one or more thermally expandable microcapsules;
- wherein
- the thermally expandable microcapsule composite body further contains a non-ionic surfactant, and
- a content of the non-ionic surfactant is from 5 to 50 mass % relative to a content of the acrylonitrile butadiene copolymer and/or the crosslinked body of the acrylonitrile butadiene copolymer.
