|1. (WO2017150643) RUBBER COMPOSITION, LAMINATE BODY, AND CONVEYER BELT|
|Title:||RUBBER COMPOSITION, LAMINATE BODY, AND CONVEYER BELT|
Provided is a rubber composition that does not lose adhesiveness to reinforcing materials, even when subjected to repeated bending fatigue. A rubber composition that is formed by blending: a rubber component that includes a diene rubber; wet silica; carbon black; and calcium carbonate. The blended amount of wet silica is 3 parts per mass or more per 100 parts by mass of the diene rubber. The BET specific surface area by nitrogen adsorption of the carbon black is 8-100 m2/g. When the BET specific surface area by nitrogen adsorption of the carbon black is X (m2/g) and the blended amount of calcium carbonate per 100 parts by mass of the diene rubber is Y (parts by mass), 0.5X+28≤Y≤X+88.
