Technical Field

The invention relates to a flange conveyer belt, in particular to a heat-resistant flange conveyer belt, and belongs to the technical field of rubber conveyer belt product processing.

Background

At present, a heat-resistant flange conveying belt used in common cement plants and steel plants generally adopts a formula design with ethylene propylene diene monomer or ethylene propylene diene monomer as main rubber, the design can bear higher working temperature, but the aging of the conveying belt bonding part can be accelerated in a long-time high-temperature environment, particularly the aging problem of the bonding part between a skirt edge and a base belt and between a partition plate and the base belt is more serious, the bonding part is cracked after aging, the crack is further extended after being mixed with impurities, and the skirt edge or the partition plate falls off, so that the conveying belt cannot be used.

A novel flange conveyer belt is urgently needed to solve the problems that in the prior art, the adhesion degree between the skirt edge and the base belt, between the partition plate and the base belt is poor and the service life of the conveyer belt is short under a long-time high-temperature environment.
