The invention relates to a tire, in particular to a tire sidewall rubber composition, a mixing method of the tire sidewall rubber composition and a tire, and the tire sidewall rubber composition comprises the following components in parts by weight: 40-60 phr of natural rubber; 40 to 60 phr of butadiene rubber; 45 to 55 phr of carbon black; 2.5 to 5.0 phr of an anti-aging agent; 1.0 to 2.0 phr of high-temperature protective wax; 0.5 phr to 3.0 phr of G-M; 2.0 to 3.0 phr of mineral oil; 4.0 to 6.0 phr of an active agent; 1.0 to 2.0 phr of a vulcanizing agent; 0.7 phr to 1.5 phr of an accelerant; wherein G-M is a mixture of glycerol and fatty acid ester. Compared with the prior art, the problem that in the prior art, due to migration of compounding ingredients, the tire sidewall discoloration can be caused is solved, and on the basis of an original anti-aging system, by forming an isolating membrane on the surface, the migration speed of other compounding ingredients is restrained, and the sidewall discoloration tendency is reduced.
本发明涉及一种轮胎,具体涉及一种轮胎胎侧胶料组合物及其混炼方法和轮胎,包括如下重量份的组分:天然橡胶40‑60phr;顺丁橡胶40‑60phr;炭黑45‑55phr;防老剂2.5‑5.0phr;高温防护蜡1.0‑2.0phr;G‑M 0.5‑3.0phr;矿物油2.0‑3.0phr;活性剂4.0‑6.0phr;硫化剂1.0‑2.0phr;促进剂0.7‑1.5phr;其中,G‑M为甘油与脂肪酸酯的混合物。与现有技术相比,本发明解决现有技术中由于配合剂的迁移会引起轮胎胎侧变色的问题,实现在原有防老体系基础上,通过在表面形成隔离膜,抑制其他配合剂的迁移速度,降低胎侧变色倾向。
