Problems solved by technology
During use, it was found that although these halogen- and antimony-containing steel cord flame-retardant conveyor belts have good flame-retardant effects, when a fire breaks out, the burning conveyor belt will produce a large amount of toxic gas and smoke, which hinders disaster relief work. If it is carried out smoothly, it will cause secondary disasters to life and property; the second is to corrode equipment and instruments; the third is to cause environmental pollution

The invention discloses an environmentally-friendly flame-retardant conveyor belt with a steel cable core used for coal mines, which efficiently solves the problem that the conventional flame-retardant conveyor belt with the steel cable core can generate a large amount of toxic and harmful gas and smoke during combustion. The flame-retardant conveyor belt mainly comprises flame-retardant cover rubber and flame-retardant core rubber which are combined with a steel cable. On the basis of meeting MT668-2008, the environmentally-friendly flame-retardant conveyor belt with the steel cable core has the advantages of no harmful and smoke generation materials (such as halogen, stibium and the like), low smoke emission and no toxic gas after the conveyor belt is burnt, cheap raw materials, low production cost and obvious economic and social benefits.
Description
technical field [0001] The invention is an environment-friendly steel cord flame-retardant conveyor belt for coal mines, specifically an improved design of the formula of a steel cord flame-retardant conveyor belt for coal mines, which does not contain halogen, antimony, etc. on the basis of meeting MT668-2008 Harmful and smoking materials. Background technique [0002] The steel cord conveyor belt is the main means of transporting coal in coal mines. The coal mine safety regulations stipulate that the belt conveyors used in coal mines must use flame-retardant conveyor belts. Steel Cord Flame Retardant Conveyor Belt", so, at present, steel cord flame retardant conveyor belts are widely used underground in major coal mining enterprises. [0003] Existing steel cord flame retardant conveyor belts all contain halogen and antimony. agents and compounding agents. During use, it was found that although these halogen- and antimony-containing steel cord flame-retardant conveyor b...
