Abstract

The invention discloses an energy-saving textile whole core flame-retardant conveyor belt and a method for manufacturing the same. The energy-saving textile whole core flame-retardant conveyor belt comprises covering layers, textile whole belt cores and belt core impregnating adhesive. The covering layers are made of powdered butadiene rubber / chlorinated polyethylene / thermoplastic polyurethane elastomers which are used as main materials, and auxiliaries for reducing loss factors are added into the main materials. The energy-saving textile whole core flame-retardant conveyor belt and the method have the advantages that formulas and processes are optimized, accordingly, the loss factors (tan delta values at the temperatures of 60 DEG C) of the covering layers can be reduced to the greatest extent, and running resistance of the energy-saving textile whole core flame-retardant conveyor belt can be reduced; radial stress lines of the textile whole belt cores are made of aramid fibers and polyester fibers, accordingly, the energy-saving textile whole core flame-retardant conveyor belt is high in strength, has thin belt bodies and is light after being impregnated and plasticized, and energy consumption of the energy-saving textile whole core flame-retardant conveyor belt in running procedures can be reduced to a great extent; the energy-saving textile whole core flame-retardant conveyor belt is produced by facing forming and dynamic vulcanization processes by the aid of extruders, and the processes are simple and are low in energy consumption and high in production efficiency.

Description

technical field [0001] The invention relates to the technical field of conveyor belts, in particular to an energy-saving fabric integral-core flame-retardant conveyor belt and a manufacturing method thereof. Background technique [0002] Conveyor belt is the main tool for material transportation in coal mines, metallurgy, mines, ports, electric power, building materials and other industries. The energy consumed by the self-weight and rolling resistance of the conveyor belt accounts for about 75% of the energy consumption of the conveyor. Research on lightweight and low rolling resistance Energy-saving conveyor belts are of great significance for reducing energy consumption of conveyors, reducing operating costs and improving economic benefits. At present, there are many achievements in research on energy-saving steel cord conveyor belts at home and abroad, but there are few researches on energy-saving research on fabric whole-core flame-retardant conveyor belts with the larg...
