Problems solved by technology

[0004] During the use of the conveyor belt, when passing the driving roller, due to the different radius of curvature, the force of each layer of material is different, so the more layers of the conveyor belt, the more prone to delamination and the shorter the service life
The existing aramid conveyor belts all use aramid canvas as the skeleton material, and the number of layers of the conveyor belt is large, which is prone to delamination, and the bonding between the aramid canvas and the rubber layer is difficult

Abstract

The invention belongs to the field of conveyor belts and particularly relates to an aramid fiber conveyor belt. The aramid fiber conveyor belt comprises an upper covering layer, an upper bonding layer, an intermediate layer, a lower bonding layer and a lower covering layer. The intermediate layer is an aramid fiber belt blank. The aramid fiber belt blank is formed by impregnating an aramid fiber belt core with a paste material and then conducting plastifying. According to the aramid fiber conveyor belt, the integral aramid fiber belt core is adopted to replace multiple layers of canvas to serve as a framework material, the layer number of the framework material is reduced, the phenomenon of delaminating is avoided, and the service life is long. Compared with a steel wire rope core conveyorbelt, the aramid fiber conveyor belt has the advantages of high strength, chemical corrosion resistance, wear resistance, good impact fatigue resistance, light weight, low operating energy consumption and the like.

Description

technical field [0001] The invention belongs to the field of conveyor belts, in particular to an aramid conveyor belt. Background technique [0002] At present, there are mainly two types of flame-retardant conveyor belts used in underground coal mines in my country: one is a flame-retardant steel cord conveyor belt for coal mines, and the other is a fabric whole-core flame-retardant conveyor belt for coal mines. Flame-retardant steel cord conveyor belt, with steel cord as the longitudinal skeleton material, has poor chemical corrosion resistance, heavy weight, high energy consumption, and is easy to tear in the longitudinal direction. The fabric whole core flame retardant conveyor belt is light in weight and has good tear resistance. Compared with the steel cord conveyor belt, it has less strength. [0003] Aramid fiber has the advantages of high temperature resistance, fire and flame retardancy, low density, low shrinkage, wear resistance, and chemical corrosion resistanc...
