Document Type and Number:
Japanese Patent JP7110551
Kind Code:
B2
Abstract:
A conveyor belt 10 is formed with a belt core body 14 covered by a cover rubber 12. The cover rubber 12 is formed with a shock resistance performance evaluation index, i.e., the product of an elongation at break Eb, a tensile strength at break TSb, and a loss tangent tan δ of 6000 or greater. The loss tangent tan δ is the ratio between a storage modulus and a loss modulus calculated from a stress when vibrations of a predetermined frequency are applied to cover rubber 12. The measurement conditions of the loss tangent tan δ are determined on the basis of a speed of an impact applied under the use conditions of the conveyor belt 10.
