Flame-retardant conveyor belts, also known as whole-core flame-retardant conveyor belts, are made of an integral belt core that is impregnated with polyvinyl chloride impregnated paste and then plasticized or vulcanized. 

  It has the characteristics of high strength, large transportation capacity, and balanced transportation. At the same time, this product It has good flame retardant, antistatic, impact resistance, wear resistance, corrosion resistance and other properties. This product is mainly suitable for underground transportation in coal mines, and can also be used for material transportation in the metallurgical and chemical industries. 

  Flame retardant conveyor belt with excellent flame retardancy, wear resistance, corrosive resistance, impact resistance, during the operation time, it has the features of high strength. Large amount of movement, balanced transportation. In the actual production, the ordinary flame retardant conveyor belt could use natural rubber, styrene- butadiene rubber, butadiene rubber, etc.

With special requirements such as acid and alkali, oil resistance, high or low temperature resistance that use chloroprene rubber, ethylene propylene rubber, nitrile rubber, etc.

  Properly use the recycled rubber could effectively reduce the cost of raw materials of the flame retardant conveyor belt. The common recycled rubber in the market are tire reclaimed rubber, latex reclaimed rubber, nitrile reclaimed rubber, butyl reclaimed rubber and EPDM reclaimed rubber. Using the recycled rubber to reduce the raw materials costs of the ordinary flame retardant conveyor belt, it is recommended to use tire recycled rubber HYL22Y6Y2Y which is low price, good performance, good compatibility with natural rubber, styrene butadiene rubber, butadiene rubber.

  When the flame retardant conveyor belt have special requirement for the oil resistance could use appropriately amount of nitrile reclaimed rubber can be used. For flame retardant conveyor belt that require heat resistance and anti-aging, it is more appropriate to add an suitable amount of EPDM reclaimed rubber. When the flame retardant conveyor belt use the reclaimed rubber to reduce the raw materials costs, generally the raw rubber and the reclaimed rubber are used together. Such as natural rubber, styrene-butadiene rubber and tire reclaimed rubber, EPDM reclaimed rubber and EPDM rubber etc.; or use raw material, the reclaimed rubber and the plastic together to prepare thermoplastic flame retardant conveyor belts such as nitrile rubber/reclaimed rubber and polyvinyl chloride/chlorinated polyethylene.

  Flame retardant conveyor belt reinforcing filling system can use carbon black, talc powder, kaolin, etc. The commonly used flame retardant is aluminum hydroxide and a small amount of antimony trioxide has a better flame retardant effect. It is recommended to use ordinary automatic oil or high aromatic oil for the softening system. Flame retardant conveyor belts have different performance requirements in different use cases and the rubber raw and auxiliary materials used are very different. When using the reclaimed rubber to produce the high performance flame retardant conveyor belts manufacturer need to choose the appropriate reclaimed rubber according to the actual needs and properly adjust the production technology and formula.
