Problems solved by technology

The ambient temperature range of the steel cord conveyor belt in the prior art is -10 to 40°C. When the temperature is lower than -10°C, the covering rubber will become hard and slippery, reducing the elasticity and troughability of the conveyor belt, affecting the Delivery effect and service life
When the ambient temperature is lower than -30°C, the covering rubber will become brittle and cracked sharply, and the bonding force between the steel wire rope and rubber will be greatly reduced, seriously affecting the conveying effect and service life

Abstract

The invention provides cold-resistant flame-retardant covering glue. The cold-resistant flame-retardant covering glue comprises 0-20 parts of natural rubber, 60-80 parts of butadiene styrene rubber, 20-30 parts of butadiene rubber, 3-6 parts of zinc oxide, 0-2 parts of stearic acid, 1-2 parts of an accelerator, 2-4 parts of an antiager; 1-2 parts of paraffin, 1.5-3 parts of sulfur, 3-8 parts of antimonous oxide, 5-12 parts of chlorinated paraffin, 50-90 parts of a solid flame retardant, 10-15 parts of a flame-retardant lubricant and 35-45 parts of carbon black. According to the cold-resistantflame-retardant covering glue provided by the invention, the good cold-resistant and flame-retardant properties are achieved under the combined action of specific components and component contents, the flame retardant property of the glue can be ensured, the effects that the glue is not hardened and embrittled at the low temperature of -60 DEG C are ensured, the glue is resistant to cracking, andthe service life of a conveyor belt can be prolonged. The invention further provides cold-resistant flame retardant middle glue, cold-resistant flame-retardant core glue and the cold-resistant flame-retardant steel wire core conveyor belt.

Description

technical field [0001] The invention relates to the technical field of conveyor belts, in particular to a cold-resistant and flame-retardant covering rubber, a cold-resistant and flame-retardant intermediate rubber, a cold-resistant and flame-retardant core rubber, and a cold-resistant and flame-resistant cord conveyor belt. Background technique [0002] Steel cord flame retardant conveyor belt is the main means of transportation in coal mines. It implements the MT668-2008 "Steel Cord Flame Retardant Conveyor Belt for Coal Mine" standard. It has flame retardancy and antistatic properties, but it is not cold-resistant. At present, in the construction of large-scale and super-large mines, modern mine ports, open-pit coal mines, and iron ore transportation systems in China, almost all high-strength steel cord conveyor belts are used as the transportation method for solid materials. The ambient temperature range of the steel cord conveyor belt in the prior art is -10 to 40°C. Wh...
