Rubber composition for preventing tire discoloration and tire

The invention provides a rubber composition for preventing tire discoloration and a tire. The rubber composition comprises, by mass, 100 parts of matrix rubber, 40-60 parts of carbon black, 3-7 parts of an active agent, 4-8 parts of an anti-aging agent, 1-5 parts of an adhesive, 1.5-3.5 parts of a vulcanizing agent, and 0.5-5 parts of a nonionic surfactant, wherein the nonionic surfactant is polyethylene glycol fatty alcohol ether and/or polyethylene glycol fatty acid ester. Compared with the prior art, the anti-aging agent is uniformly dispersed in the formula by using the nonionic surfactant, the solubility of the anti-aging agent in matrix rubber is improved, and the tire sidewall appearance can be improved and the sidewall discoloration problem can be solved while the tire sidewall performance is not influenced. 本申请提出了一种防止轮胎变色的橡胶组合物和轮胎，所述橡胶组合物以质量份计，包括：100份基体橡胶，40-60份炭黑，3-7份活性剂，4-8份防老剂，1-5份粘合剂，1.5-3.5份硫化剂，0.5-5份非离子型表面活性剂；所述非离子型表面活性剂为聚乙二醇脂肪醇醚和/或聚乙二醇脂肪酸酯。与现有技术相比，本申请使用非离子型表面活性剂使防老剂在配方中均匀分散，提升防老剂在基体橡胶中的溶解度，能在不
