A wearproof adhesive formula for radial tires is disclosed. The wearproof adhesive comprises following components by mass: 28-32 parts of natural rubber SMR20, 68-72 parts of low cis polybutadiene, 1.8-2.2 parts of p-tert-butylphenol formaldehyde resin, 3-4 parts of zinc oxide, 1.8-2.2 parts of stearic acid, 2.8-3.2 parts of a plasticizer A, 2.8-3.2 parts of an anti-ageing agent 4020, 0.8-1.2 parts of an anti-ageing agent RD, 1.8-2.2 parts of aromatic oil, 0.45-0.55 part of micro-crystalline wax, 1-1.5 parts of insoluble sulfur IS6033, 1.5-2 parts of a promoter DZ, 28-32 parts of carbon black N375 and 38-42 parts of carbon black N234. The wearproof adhesive prepared by adopting the natural rubber SMR20 and the low cis polybutadiene has high hardness, rebound resilience, wear resistance, ageing resistance and flexing resistance. A rubber material filled by the carbon black N375 and the carbon black N234 together has good vulcanization characteristics. A vulcanized rubber material has high tensile strength, high stress at definite elongation and high wear resistance.
