The composition of the conveyor belt generally comprises a belt core, a belt core glue and a cover glue; the belt core is a framework of a conveying belt and is used for bearing all the load during working, and steel wire ropes or fiber fabrics are generally adopted; the belt core glue is positioned between the belt core and the covering glue and is used for improving the bonding strength between the belt core and the covering glue; the cover rubber is a protective layer of the conveyor belt, and is in direct contact with the transported goods, and high strength, wear resistance and ageing resistance are required. The conveyer belt is usually made of steel wire ropes with steel wire strand cores, and the conveyer belt produced by the steel wire ropes with the steel wire strand cores has the characteristics of strong impact resistance, small use elongation, high-speed transmission and the like. However, under some special environmental conditions, the conveyer belt is required to have high strength and high elongation, but the conveyer belt produced by the steel wire rope with the steel wire strand cores cannot achieve high strength and high elongation, so that the application range of the conveyer belt is affected. And the ignition point of some existing refractory conveyor belts is lower, and the refractory material layer is easy to oxidize and has insufficient strength, so that the service life of the conveyor belt is shortened.

Therefore, how to provide a closely-spaced high-strength conveyor belt which not only has high strength but also has high elongation and can prevent oxidation and increase service life is one of the technical problems to be solved in the art.
