Abstract

The invention discloses a tube-shaped flame retardant conveying belt with fabric laminations for a coal mine, which solves the problem that exiting products are not suitable for usage for underground conveying belts with laminations for coal mines. The conveying belt is characterized by comprising an upper flame retardant covering adhesive layer, a lower flame retardant covering adhesive layer, a side adhesive, skeleton layers, a flame retardant bonding layer and a buffering layer. A flame retardant bonding adhesive is used for bonding among the skeleton layers, among the skeleton layers and buffering layer and between the buffering layer and the upper flame retardant covering adhesive layer to form a whole, and formulas of the flame retardant bonding adhesive and a flame retardant covering adhesive are designed. Flame retardant epoxide resin (EP) canvas which is subjected to flame retardant impregnation processing serves as a skeleton, produced conveying belts have high pipe forming capability, conveying belt bodies have suitable softness, and produced conveying belts can meet turning requirements of tube-shaped conveying belts at different levels and requirements of tube-shaped conveying machines on physical mechanical properties of tube-shaped conveying belts; a flame retardant bonding adhesive material has high infiltration capacity on skeleton materials, after sulfuration, the bonding force of the flame retardant bonding adhesive material is large, dynamic heat is small, and the flame retardant bonding adhesive material has repeated bending fatigue resistance; and abrasion resistant and yielding resistant performance of the flame retardant bonding adhesive material is improved, and the flame retardant performance meets underground flame retardant requirements for coal mines.

Description

Technical field [0001] The invention relates to a conveyor belt, in particular to a flame-retardant conveyor belt with flame-retardant EP canvas as the skeleton 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 tubul...
