Definitions
- the present invention relates to a conveyor belt, and more particularly to a conveyor belt that can improve both the wear resistance and impact resistance performance of an upper cover rubber.
- the conveyor belt generally has a structure in which an upper cover rubber is laminated on the outer peripheral side of a core body made of a canvas layer or a steel cord layer, and a lower cover rubber is laminated on the inner peripheral side of the core body.
- a conveyed product is put into the upper cover rubber, and the conveyed product is placed on the upper cover rubber and conveyed.
- the upper cover rubber is most impacted by the transported material. Due to this impact, damage to the upper cover rubber progresses over time. In the case of a conveyed product having a sharp protrusion shape on the surface, damage to the upper cover rubber becomes significant.
- Patent Document 1 Conventionally, various conveyor belts that achieve both wear resistance and impact resistance have been proposed (for example, see Patent Document 1).
- the conventional proposal including Patent Document 1 is that a special rubber composition excellent in both wear resistance and impact resistance is used for the upper cover rubber (paragraph 0145 of Patent Document 1).
- it is difficult to achieve both wear resistance and impact resistance with a single rubber composition and there is a halfway tendency that one performance does not improve so much or both performances do not improve so much.
- An object of the present invention is to provide a conveyor belt capable of improving both the wear resistance and impact resistance of the upper cover rubber.
- the conveyor belt of the present invention is a conveyor belt in which a core body is embedded between an upper cover rubber and a lower cover rubber.
- the loss factor at 20 ° C. of the wear resistant layer is 0.03 or more and 0.25 or less and the loss elastic modulus is 0.20 MPa or more and 6.50 MPa or less
- the loss at 20 ° C. of the shock resistant layer The coefficient is 0.15 or more and 0.70 or less
- the loss elastic modulus is 1.5 MPa or more and 30.0 MPa or less.
- the wear resistant layer having the loss coefficient and the loss elastic coefficient set in a specific range is disposed on the upper cover rubber, thereby causing wear due to friction generated between the wear resistant layer and the conveyed product. Can be difficult. Further, by disposing the impact resistant layer having the loss coefficient and the loss elastic coefficient in a specific range on the upper cover rubber, it is possible to prevent damage caused by the impact received from the conveyed object by the impact resistant layer.
- the wear-resistant layer is more impact-resistant because the impact-resistant layer arranged on the inner circumference side exhibits excellent impact resistance over a long period of time and absorbs the impact caused by the loaded material. Damage is less likely to occur.
- a wear-resistant layer with excellent wear resistance and an impact-resistant layer with excellent impact resistance are provided separately, and the synergistic effect of these layers increases both the wear resistance and impact resistance of the upper cover rubber. It is advantageous to improve and extend the useful life of the conveyor belt.
- the wear-resistant layer may be configured to be disposed on the outermost peripheral side of the upper cover rubber. According to this specification, since the wear-resistant layer is disposed at a position where the conveyed product is in direct contact, it is most advantageous for suppressing wear of the upper cover rubber.
- the layer thickness of the wear-resistant layer is, for example, 2 mm or more and 30 mm or less. According to this specification, it is possible to obtain sufficient wear resistance while avoiding deterioration of the bending resistance of the conveyor belt without increasing the thickness of the wear-resistant layer.
- the layer thickness of the impact resistant layer is, for example, 2 mm or more and 30 mm or less. According to this specification, it is possible to obtain sufficient impact resistance while avoiding deterioration of the flex resistance of the conveyor belt without increasing the thickness of the impact resistant layer.
- the specification can be such that the thickness of the impact-resistant layer is thicker at the center in the belt width direction than at both ends in the belt width direction.
- the conveyor belt On the belt carrier side where the conveyed product is put into the upper cover rubber, the conveyor belt has a trough shape. Therefore, both ends of the belt in the belt width direction have a smaller impact force received from the loaded material than the central portion in the belt width direction. Therefore, according to this specification, the thickness of the impact-resistant layer at both ends in the belt width direction is not increased unnecessarily, so that the bending resistance of the conveyor belt is improved, which is advantageous for weight reduction. Thereby, energy required in order to drive a conveyor belt can be reduced.
