PURPOSE: To provide a coveyer belt suitable for conveying adhesive material such as oil sand or the like by forming the belt by one or moer cover layers containing surface tack eliminator and a core material layer, and interposing layers for preventing migration of surface tack eliminator between both layers.
CONSTITUTION: A conveyer belt is formed by stacking a core material layer 2 formed by a metallic cord such as steel or the like, nylon, natural rubber and so on, cover layers 3 formed by mixing material having small interfacial tension and critical surface energy as a surface tack eliminator with methacrylic resin or the like, and migration preventive layers 4 formed by compound material of fiber layer, plastic layer and rubber layer, which are interposed therebetween. Thus, a conveyer belt for suitable for conveying adhesive material such as oil sand or the like can be obtained.
