A highly elastic novel rubber seal material relates to the field of production of rubber seal materials. The highly elastic novel rubber seal material comprises, by weight, 20 parts of ethylene propylene rubber, 10-13 parts of carbon black, 3-4 parts of calcium carbonate, 4-10 parts of an antioxidant mixture, 0.15-0.3 parts of a dispersant polyethylene wax, 10-25 parts of an accelerant mixture comprising N-cyclohexyl-2-benzothiazole sulfonamide and bis-pentamethylenethiuram tetrasulfide, 0.1-0.2 parts of a vulcanizing agent sulfur and 0.15-0.3 parts of a fire retardant ammonium polyphosphate ester The accelerant mixture comprising N-cyclohexyl-2-benzothiazole sulfonamide and bis-pentamethylenethiuram tetrasulfide is used to make the vulcanization of the ethylene propylene rubber further crosslinked and increases the crosslinking degree, so the elasticity of the ethylene propylene rubber is improved. The novel rubber material prepared in the invention has the characteristics of high elasticity, high resilience, reduced compressibility and reduced permanent deformation.
