Abstract
A rubber composition capable of manufacturing a sheet transport roller having an excellent friction coefficient and wear resistance. A sheet transport roller rubber composition contains an ethylene-α-olefin-diene copolymer as a base rubber, a sulfur-based crosslinking agent, and a coumarone-indene resin. It is preferable that the sheet transport roller rubber composition be obtained by mixing the base rubber and the coumarone-indene resin at a temperature equal to or higher than a softening point of the coumarone-indene resin to prepare a mixture, and then mixing this mixture with a sulfur-based crosslinking agent.
Claims5
A sheet transport roller rubber composition, containing
- an ethylene-α-olefin-diene copolymer as a base rubber, a sulfur-based crosslinking agent, and a coumarone-indene resin,
- wherein a content of the coumarone-indene resin is 4 parts by mass to 15 parts by mass with respect to 100 parts by mass of the base rubber.
