Title:
ゴム組成物、その製造方法及びタイヤ
Document Type and Number:
Japanese Patent JP6685902
Kind Code:
B2
Abstract:
An object of the present invention is to provide a rubber composition in which processability, an abrasion resistance and a rolling resistance can be consistent well in a tire to a high degree, and parts and members for the tire. Also, an object of the present invention is to inhibit a shrink of the rubber composition. In the present invention, the rubber composition is blended with 90 to 130 parts by weight of carbon black having a large particle diameter based on 100 parts by mass of the rubber component, and a glycerin fatty acid ester composition, whereby the carbon black having a large particle diameter is improved in dispersibility in the rubber composition. This allows the unvulcanized rubber composition to be enhanced in a processability by reducing a viscosity thereof, and the rubber composition for a tire which is improved in an abrasion resistance, rolling resistance and a processability, and a tire produced by using the above rubber composition are provided.
