Problems solved by technology

However, the steel wire rope is heavy and consumes a lot of energy. The steel wire rope is easy to rust in the humid environment of the coal mine, and the joint time is long, so the diameter of the driving drum is required to be large.

Abstract

The invention discloses a tubular anti-flaming aramid fiber fabric lamination conveyor belt for a coal mine, which solves the problem that the conventional conveyor belt is inconvenient to use as a tubular conveyor belt under a coal mine well. The tubular anti-flaming aramid fiber fabric lamination conveyor belt is characterized in that a novel conveyor belt product is produced for being used under the coal mine well through material selection of a framework material, a design of a core body structure, adhesion of an adhesive layer, formulation design of covering the adhesive layer and the like. The tubular anti-flaming aramid fiber fabric lamination conveyor belt provided by the invention uses aramid fiber fabrics as a framework layer, so that a finished conveyor belt has strong pipe formation capability; a belt body has proper flexibility; and the different-level cornering requirements of the tubular belt can be met. A vulcanized anti-flaming bonding adhesive material is large in bonding force, is small in dynamic themogenesis, resists repeated bending fatigue, and has excellent anti-flaming property. An anti-flaming covering adhesive material is compounded by different adhesive types through a modifier and a fire retardant in a synergistic manner, and uses materials such as aramid fiber pulp, a coupling dispersant and an anti-flaming tackifier, so that the strength of the adhesive material is enhanced; the wear resistance and the anti-flexural property can be improved, particularly the cutting resistance is improved; the rolling resistance is reduced; and the requirements on the anti-flaming property under the coal mine well can be met.

Description

Technical field [0001] The invention relates to a conveyor belt, in particular to a flame-retardant conveyor belt with an aramid fabric as the skeleton layer and a flame-retardant covering rubber layer. Background technique [0002] Tubular conveyor belt is a special conveyor belt used in conjunction with round tube belt conveyors. The round tube belt conveyor is a special belt conveyor developed on the basis of the trough belt conveyor. After receiving material at the tail of the conveyor, the flat conveyor belt is guided into a circular tube by applying force through the idler group in the transition section, so that the conveyed material is sealed in the tube, and then gradually unfolded into a trough discharge at the transition section of the head. , the return journey is rolled into a cylinder again, so as to realize the equipment of airtight conveying and reciprocating conveying of materials in the whole conveying line. [0003] The service conditions of the tubular ...
