The invention relates to the technical field of sidewall rubber, in particular to sidewall rubber of an underground coal mine flame-retardant tire, which is prepared from the following raw materials in parts by mass: 20 to 50 parts of natural rubber, 20 to 40 parts of emulsion polymerized styrene-butadiene rubber, 30 to 50 parts of butadiene rubber, 0 to 15 parts of MCSM rubber, 2 to 10 parts of active agent zinc oxide, 30 to 60 parts of high wear-resistant carbon black N330, 0 to 15 parts of white carbon black, 1 to 2 parts of anti-aging agent TMQ, 1 to 3 parts of anti-aging agent 6PPD, 0.5 to 2.5 parts of protective wax and 1 to 3 parts of dispersing agent FS-97. The flame retardant is prepared from the following raw materials in parts by weight: 0.6-2 parts of an accelerant CZ, 0.1-0.4 part of a scorch retarder, 2-5 parts of chlorinated paraffin, 10-35 parts of decabromodiphenyl ether, 5-15 parts of antimony trioxide, 0-15 parts of zinc borate and the like. The invention also provides a preparation method which comprises the following steps: weighing the raw materials, primarily mixing the master batch, further mixing the master batch and mixing the final mixed rubber. The oxygen index of the sidewall rubber can be increased to 22% or above by optimizing and adjusting a raw rubber system and an overall formula and combining with matched application of the flame-retardant material.
