The invention discloses tire rim rubber as well as a preparation method and application thereof, and belongs to the technical field of rim rubber. The problem that in the prior art, the batch stability of tire rim rubber with natural rubber as a raw material is poor is solved. The tire rim rubber comprises the following components in parts by weight: 100 parts of cis-1, 4-polyisoprene rubber, 5-10parts of zinc oxide, 1-2 parts of anti-aging agent RD, 1-2 parts of anti-aging agent 4020, 2-10 parts of a tackifying resin, 0.5-2 parts of a cobalt salt, 3-5 parts of aromatic hydrocarbon oil, 60-80parts of N660 carbon black, 10-20 parts of N220 carbon black, 0.5-1 part of calcium oxide, 1-5 parts of a methylene receptor compound, 1-5 parts of methylene donor compound, 0.2-0.5 part of scorch retarder CTP, 1.5 parts of sulfenamide accelerant, and insoluble sulphur (wherein 5-7 parts of sulphur). The tire rim rubber generates little heat in the dynamic use process, and is high in quality, good in stability, high in bonding strength and high in rubber coating rate.
