The invention provides an epoxidized natural rubber composition, a preparation method thereof and tread rubber. The rubber material is prepared from the following raw materials: epoxidized natural rubber, other epoxidized rubber, a filler, an activator, an anti-aging agent, a plasticizer, an accelerant and a vulcanizing agent, based on the total amount of epoxidized natural rubber and other epoxidized rubber as 100 parts by weight, the composition comprises 50-95 parts by weight of epoxidized natural rubber; preferably, 60-90 parts by weight; 5-50 parts by weight of other epoxidized rubber; and preferably, 10-40 parts by weight of the composition. The preparation method of the epoxidized natural rubber is improved, the preparation process is simplified, and the prepared epoxidized natural rubber composition can be used for preparing all-steel radial tire treads.
