SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a high temperature resistant conveyer belt aims at solving among the prior art canvas sandwich layer in the high temperature resistant conveyer belt and easily elongates, easy cracked problem.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a high-temperature-resistant conveying belt comprises an upper EVM rubber layer, a lower EVM rubber layer and at least one canvas layer arranged between the upper EVM rubber layer and the lower EVM rubber layer, wherein a heat insulation layer is further arranged between the upper EVM rubber layer and the canvas layer.

The utility model discloses a further technical scheme does, the insulating layer is thermal-insulated fibrous layer.

The further technical scheme of the utility model does, the insulating layer is basalt fiber cloth.

The utility model discloses a further technical scheme does, be equipped with the three-layer canvas layer between insulating layer and the lower EVM rubber layer.

The utility model discloses a further technical scheme does the insulating layer all is equipped with the core glue film with being located between the canvas layer on upper strata, between the adjacent two-layer canvas layer and between EVM rubber layer and the canvas layer that is located the lower floor down.

The further technical proposal of the utility model is that the core glue layer is maleic anhydride modified EVM rubberizing.

The beneficial effects of the utility model are that:

when the heat insulation layer works in a high-temperature environment, the heat insulation layer can effectively prevent heat from being transferred to the canvas layer through the upper EVM rubber layer, the defect that the canvas layer is easy to age and degrade at a high temperature is effectively overcome, the tensile strength and the adhesive strength retention rate of the canvas layer are improved, and the service life of the conveying belt is prolonged.
