WIPO Patent Application WO/2013/105655

Kind Code:

A1

Abstract:

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.
