Abstract

The invention relates to a composition for a flame-retardant conveying belt and the flame-retardant conveying belt. The composition comprises the following components: natural rubber, butadiene styrene rubber, butadiene rubber, an activating agent, an anti-aging agent, carbon black, a dispersing agent, sulfur, a vulcanization accelerator and a flame retardant; the conveying belt comprises a first flame-retardant layer, a first aluminum foil layer, a core layer, a second aluminum foil layer and a second flame-retardant layer from top to bottom, wherein '[]' shaped edge covering structures are symmetrically arranged on two opposite side edges of the conveying belt respectively. A selected formula system of the composition for the flame-retardant conveying belt disclosed by the invention can reach excellent effects of stretch resistance, wear resistance and flame retardance; the first flame-retardant layer, the second flame-retardant layer and a flame-retardant adhesive solution adopted by the conveying belt can be used for effectively preventing the surface of the conveying belt from being scalded and burnt, thus reducing the production cost; patterns arranged on the upper surface can be used for improving the wear resistance; the aluminum foil layers can be used for effectively blocking and preventing the erosion caused by external heat and oxide; the arrangement of the core layer structure and '[]' edge covering structures can be used for preventing the conveying belt from being torn, laminated or dropped.

Description
