Problems solved by technology

However, the steel wire rope belt is heavy, consumes a lot of energy, and is easy to tear. The coating on the surface of the steel wire rope is easy to peel off after repeated operation. The belt is damaged by the impact of materials during long-term operation, which may cause the steel wire rope to rust and cause belt breakage. The diameter of the barrel is required to be larger
The whole core flame retardant conveyor belt is woven with nylon fiber, polyester fiber and cotton fiber into a whole belt core, impregnated with polyvinyl chloride flame retardant plastic paste and then plasticized, the belt body is light, the joint is tear-resistant The performance is good, but the belt body is stiff, the grooving is poor, and the service life is short. If the conveying inclination exceeds 16°, it will be difficult to use if the object slips
Due to the limitation of the strength of the skeleton material, it is difficult to manufacture a full-core conveyor belt with a belt strength exceeding 3150N / mm

Abstract

The invention discloses a flameretardant conveyor belt for an aramid fiber core. A pull-resistant framework layer made from aramid fiber fibre. The flameretardant conveyor belt comprises an aramid fiber framework layer, two buffer layers and a flameretardant coverage glue layer, wherein the aramid fiber framework layer is a straight-longitude and straight-latitude structure, two sides of the aramid fiber framework layer are respectively provided with the buffer layer, two sides of the aramid fiber framework layer and the buffer layers are respectively glued with flameretardant bonding glue, the aramid fiber framework layer is bonded with the buffer layers by the flameretardant bonding glue, and the buffer layers are bonded with the flameretardant coverage glue layer by the flameretardant bonding glue. The flameretardant conveyor belt is good in integrated performance, high in the strength of a belt body, light in weight, good in adhesive force, flameretardant, static electricity-resistant, and good in corrosion resistance; the flameretardant conveyor belt is long in service life, low in operation kinetic energy consumption, small in the diameter of a transmission roller, and low in equipment cost; and the flameretardant conveyor belt is less in long-distance jointing times, low in integrated cost, convenient to joint, and good in jointing durability, so that the transportation requirement of multi-variety under a coal mine well can be met.

Description

Technical field [0001] The invention belongs to a flame-retardant conveyor belt for underground coal mines, in particular to an aramid-core flame-retardant conveyor belt with aramid fibers as the tensile skeleton layer. Background technique [0002] Conveyor belt is a kind of composite material, which is generally composed of steel wire rope, nylon polyester and other fibers as the skeleton, and the upper and lower layers are covered with flame-retardant rubber. The skeleton layer bears all the tension during application. The upper and lower covering glues are in direct contact with the conveyed material, preventing the impact, cutting and wear of the material on the skeleton material in the middle. The skeleton material used as a conveyor belt requires high strength, good fatigue resistance, stable bonding, convenient joints, and light weight. Moreover, due to the specific application environment and conditions in coal mines, the conveyor belt used must also have high flam...
