Title:
CONVEYOR BELT
Document Type and Number:
WIPO Patent Application WO/2020/137048
Kind Code:
A1
Abstract:
A conveyor belt 10 is formed by covering a belt core 14 with cover rubber 12. The cover rubber 12 is configured such that at least a portion of the surface thereof has a micro-asperity structure, and as a result of the micro-asperity structure, the surface roughness is 1 µm to 12 µm, the sharpness is 2 to 9, and the specular gloss with an incident angle of 60° is 0.1 to 10. In particular, it is preferable that the surface roughness be 2 µm to 5 µm, that the sharpness be 3 to 5, and that the specular gloss with an incident angle of 60° be 0.1 to 3. Due to this configuration, the conveyor belt 10 is less likely to have external appearance defects resulting from bloom.
