RUBBER COMPOSITION FOR CONVEYOR BELTS RUBBER FOR CONVEYOR BELT COVERS AND CONVEYOR BELT

摘要

Provided are: a rubber composition for conveyor belts which has achieved a good balance between cutting resistance and workability during the production without lowering wear resistance; a rubber for conveyor belt covers which is obtained using the rubber composition; and a conveyor belt which is obtained using the rubber composition. Specifically provided are: a rubber composition for conveyor belts which contains at a specific ratio (A) a rubber component that contains at a specific ratio a styrene butadiene rubber mixture which contains one or more styrene butadiene rubbers having a styrene content of 20 25% by mass and one or more styrene butadiene rubbers having a styrene content of more than 25% by mass but 50% by mass or less and has an average styrene content of 28 35% by mass and at least one rubber that is selected from among butadiene rubbers and natural rubbers (B) silica (C) a resin and (D) a specific carbon black; a rubber for conveyor belt covers which is obtained using this rubber composition; and a conveyor belt cover which is obtained using this rubber composition.
