Under the special condition, because of the high temperature probably leads to the conveyer belt burning, when the conveyer belt burns fire-retardant layer, its inside fire retardant exposes, can play the effect of putting out a fire of preferred, has effectively prevented the further emergence of conflagration, has guaranteed property safety and life safety.

In one embodiment of the present application, the flame retardant is one or more of a halogen flame retardant, a phosphorus flame retardant, and a nitrogen flame retardant.

In one of the embodiments of this application, heat-resisting wear-resisting conveyer belt still includes rubber warning layer, rubber warning layer sets up between fire-retardant layer and the last rubber coating layer, rubber warning layer colour with go up the rubber coating layer colour difference and form the contrast. After the upper rubber coating layer is worn or burnt by materials, the rubber warning layer is exposed to warn operators, the conveying belt is damaged, and the condition that the conveying belt is used continuously under the unknowing condition to cause sudden breakage of the conveying belt to endanger personal safety or property safety is avoided.

In one embodiment of the present application, the upper rubber coating layer is black, and the rubber warning layer is red, yellow, or blue.

One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

1. the upper rubber layer and the lower rubber layer are made of high-temperature-resistant ethylene propylene rubber, and then nylon mesh cloth or steel cord mesh cloth with high extensibility is added into the upper rubber layer to reduce impact abrasion of mineral aggregate on the conveying belt, meet the bearing requirement on high-temperature mineral aggregate and effectively prolong the service life of the conveying belt;

2. the upper heat-insulating layer and the lower heat-insulating layer which are arranged above and below the framework layer are used for isolating heat transferred from high-temperature mineral aggregate on the conveying belt to the framework layer, so that the possibility of damage and even burning of the framework layer caused by long-time high-temperature roasting is reduced;

3. under special conditions, the conveyor belt can be burnt due to overhigh temperature, and when the conveyor belt is burnt to the flame-retardant layer, the flame retardant in the conveyor belt can play a better fire extinguishing role, so that further fire disasters are effectively prevented;

4. the rubber warning layer that spills below after covering the rubber layer wearing and tearing warns operating personnel to change the conveyer belt to reduce the risk that the conveyer belt breaks suddenly and leads to the incident.
