Abstract
Provided is a conveyor belt. The upper cover rubber has a configuration in which a wear resistance layer and an impact resistance layer are layered in this order from an outer peripheral side of the conveyor belt. The wear resistance layer has a loss coefficient of from 0.03 to 0.25 and a loss elastic coefficient of from 0.20 MPa to 6.50 MPa at 20° C. The impact resistance layer has a loss coefficient of from 0.15 to 0.70 and a loss elastic coefficient of from 1.5 MPa to 30.0 MPa at 20° C.
Claims3
A conveyor belt comprising:
- an upper cover rubber comprising:
- a wear resistance layer;
- and
- an impact resistance layer;
- the wear resistance layer and the impact resistance layer being layered in this order from an outer peripheral side of the conveyor belt;
- a lower cover rubber;
- and
- a core embedded between the upper cover rubber and the lower cover rubber;
- wherein
- the wear resistance layer is rubber which has a loss coefficient of from 0.03 to 0.25 and a loss elastic coefficient of from 0.20 MPa to 6.50 MPa at 20° C.,
- the impact resistance layer is rubber which has a loss coefficient of from 0.15 to 0.70 and a loss elastic coefficient of from 1.5 MPa to 30.0 MPa at 20° C.,
- the wear resistance layer exhibits increased wear resistance as compared with the impact resistance layer,
- the impact resistance layer exhibits increased impact resistance as compared with the wear resistance layer, and
- a layer thickness of each of the wear resistance layer and the impact resistance layer is from 2.0 mm to 30.0 mm.
