The invention discloses a high-temperature-resistant yellowing-resistant colored tire tread rubber. The rubber comprises the following components in percentage by weight: 17-24% of natural rubber, 16-26% of ethylene propylene diene monomer, 12-20% of butadiene rubber, 18-26% of high-dispersion white carbon black, 2.3-3.2% of tackifying resin 1102, 0.8-1.5% of a silane coupling agent JHS-69, 1.8-2.5% of pigment, 4-5.5% of processing oil P-150, 1.8-2.5% of a vulcanizing agent LUREROX F40, 0.3-1.2% of an accelerator TAIC-70, 0.2-0.5% of a peptizer, 1.1-2.5% of an anti-aging agent, 2.3-3% of an active agent ZnO, 0.8-1.5% of an active agent SA, and 0.5-1.2% of an active agent PEG-4000. The invention further provides a synthesis method of the high-temperature-resistant yellowing-resistant colored tire tread rubber. In virtue of the synthesis method, the prepared rubber has excellent performance, guaranteedthe color stability and no performance attenuation phenomenon, it can still be guaranteed that the product is manufactured and used stably at a high temperature in summer, and a high practical value is achieved.
