The invention discloses a sidewall rubber material of diagonal tyre. The rubber material is characterized by being composed of the following components in parts by weight: 50 to 60 parts of butyl rubber, 20 to 30 parts of isoprene rubber, 3 to 5 parts of polyether polyol, 4 to 6 parts of toluene diisocyanate, 8 to 10 parts of filling material, 1 to 2 parts of diaminodichlorodiphenyl methane, 0.6 to 0.8 part of dibutyl phthalate, 2 to 4 parts of diatomite, 4 to 6 parts of naphthenic oil, and 0.4 to 0.7 part of polypropylene powder. The filling material can reduce the dust during the rubber blending process, and can be easily dispersed in rubber, and the cost of rubber products is reduced. The durability of the prepared rubber material is maintained, moreover, the resistance of tyre during the rolling process is reduced, the tyre can bear large twist deformation, and thus the operation stability is improved.
