Problems solved by technology

[0003] Traditional conveyor belt manufacturers and research institutes at home and abroad are developing conveyor belts that can withstand the high temperature of cement clinker, but there has been no major progress. The reason is that almost all manufacturers focus on the high temperature resistance of the rubber layer on the conveyor belt. However, the tolerance of the whole skeleton is ignored, so the service life of the conveyor belt has not been greatly improved, and the main defect in the use of the high-temperature resistant conveyor belt is that when conveying high-temperature materials, the rubber on the working surface of the belt is aging and tortoise. Cracks, the first skeleton layer of the working surface and the covering glue fall off, resulting in scrapping and short service life
[0004] Chinese patent CN102530470A discloses a high-temperature-resistant conveyor belt with a diaphragm and a sidewall, including a base belt, a diaphragm and a skirt, wherein a metal plate is arranged inside the diaphragm, and there are several channels on the metal plate. The diaphragm is fixed on the base belt by fasteners, which solves the defect that the rubber layer is easy to fall off when the conveyor belt is used at high temperature, but this invention only solves the problem of rubber layer falling off, and does not improve the overall life expectancy
Chinese patent CN102167213B discloses a high temperature resistant conveyor belt, the production materials include EPDM rubber, nitrile rubber, main crosslinking agent, auxiliary crosslinking agent, activator, anti-aging agent, adhesive, adhesion promoter, Reinforcing agent, dispersant, softener, improve thermal bonding performance by adding adhesive, but only prolong life, can not improve heat resistance and applicability
