The invention discloses an anti-aging non-discoloring sidewall rubber composition and a preparation method thereof, wherein the rubber composition comprises the following raw materials: raw rubber, carbon black, zinc oxide, stearic acid, paraffin, octyl phenolic resin, a first silane coupling agent, a first anti-aging agent, a second anti-aging agent, white carbon black, a white carbon black dispersing agent, soybean oil, an organic porous silicon loaded anti-aging agent, TiO2, a first accelerant, a scorch retarder, a second accelerant and sulfur. According to the anti-aging non-discoloring sidewall rubber composition disclosed by the invention, the organic porous silicon loaded anti-aging agent is introduced, the anti-aging agent has a porous structure, the anti-aging agent is loaded and grafted on the surface of the anti-aging agent, and the loaded and grafted anti-aging agent cannot migrate to the surface to be sprayed out in the rubber composition, so that a better anti-aging effect is achieved, and the problem of surface discoloration of the tire sidewall is solved.
本发明公开了一种耐老化不变色的胎侧橡胶组合物及其制备方法,该橡胶组合物包括如下原料:生胶,炭黑,氧化锌,硬脂酸,石蜡,辛基酚醛树脂,第一硅烷偶联剂,第一防老剂,第二防老剂,白炭黑,白炭黑分散剂,大豆油,有机多孔硅负载防老剂,TiO2,第一促进剂,防焦剂,第二促进剂,硫磺。本发明耐老化不变色的胎侧橡胶组合物中,引入了有机多孔硅负载防老剂,该防老剂具有多孔结构同时在其表面负载接枝上了防老剂,其负载接枝上的防老剂不会在橡胶组合物中迁移至表面喷出,因而具有更好的抗老化效果,解决了轮胎胎侧的表面变色问题。
