Abstract:
      The development of 36. 00R51 flame retardant and giant off-the-road radial tire was introduced.According to the operating conditions of slag trucks，the oxygen indexes of the flame retardant tread compound and sidewall compound were increased to above 24% by using decabromodiphenyl ether，zinc borate and antimony trioxide flame retardant materials，and their flame retardant performances were also greatly improved.The 36. 00R51 flame retardant and giant off-the-road radial tire produced with flameretardant tread compound and sidewall compound could effectively prevent the tire from burning failure caused by high-temperature waste water，and its average service life reached 154 d，40% longer than that of competitive tires，which reduced the use cost of the tire and the safety risk in the transportation process of slag trucks.
