The invention discloses high-strength anti-yellowing rubber. The high-strength anti-yellowing rubber comprises the following components: 70-90 parts of natural rubber, 10-30 parts of butadiene rubberBR9000, 3.5-6 parts of zinc carbonate, 1-2 parts of stearic acid, 1-2 parts of an anti-aging agent BHT, 0.3-0.8 part of an accelerator NS, 1-2 parts of an anti-yellowing promoter ZDTP-50, 4-6.5 partsof polyethylene glycol, 35-55 parts of white carbon black, 25-35 parts of titanium dioxide, 0.8-2 parts of a coupling agent Si69-50, 5-10 parts of a vulcanizing agent, 15-35 parts of white mineral oil, wherein the vulcanizing agent is a sulfur dichloride-loaded mesoporous molecular sieve. The high-strength anti-yellowing rubber is prepared mainly from the natural rubber and butadiene rubber, and the whole yellowing resistance is improved through addition of the anti-yellowing promoter ZDTP; and sulfur dichloride as a key to the high-strength anti-yellowing rubber is loaded on the mesoporous molecular sieve, vulcanization is achieved on the one hand, vulcanization can also be promoted on the other hand, and the mechanical properties of the rubber material are also improved.
