The invention discloses heat-resistant tread rubber, and belongs to the technical field of tire rubber. The heat-resistant tread rubber is prepared from, by weight, 70-90 parts of natural rubber, 30-50 parts of chloroprene rubber, 10-20 parts of butyl rubber, 2-3 parts of stearic acid, 1-3 parts of vulcanizer, 4-8 parts of aluminum hydroxide filler, 5-10 parts of softener, 5-10 parts of reinforcer and 2-3 parts of antiager, wherein the reinforcer is acetylene black or white carbon black, and the softener is a silane coupling agent. The invention further discloses a preparation method of the heat-resistant tread rubber. Due to the unique formula of the heat-resistant tread rubber, the heat stability of a tire is high, the hardness of the tire is moderate, and both heat resistance and fatigue resistance can meet requirements. The preparation method of the rubber is simple and environmentally friendly, and the prepared rubber can meet use requirements, is durable and has excellent economic benefits and practicality.
