The invention discloses dynamic ozone aging resistant tire sidewall rubber, which is prepared on the basis of universal rubber natural rubber, butadiene rubber and butadiene styrene rubber according to the characteristics that the sidewall of a tire is subjected to flex stretching for a long time and is easy to be subjected to ozone aging. Chlorosulfonated polyethylene rubber with good ozone resistance, an anti-aging agent 6PPD with good dynamic ozone aging resistance and a proper amount of an anti-aging agent DTPD with good static ozone aging resistance are added, an ultraviolet light absorber UV-0 is added into a rubber material, and the ultraviolet light absorber UV-0 of the product is well matched in the rubber and the chlorosulfonated polyethylene rubber. Meanwhile, in order to further improve the ozone aging resistance of the tire sidewall rubber and reduce the cost of the rubber material, high-strength butyl recovery rubber with remarkable ozone aging resistance is added.
本发明公开了一种耐动态臭氧老化胎侧胶,根据轮胎胎侧长时间受到屈挠拉伸以及容易受到臭氧老化的特点,在通用性橡胶天然橡胶,顺丁橡胶,丁苯橡胶的基础上,加入耐臭氧能力较好的氯磺化聚乙烯橡胶、耐动态臭氧老化较好的防老剂6PPD及适量的耐静态臭氧老化较好的防老剂DTPD,在胶料中加入紫外线吸收剂UV‑0,该产品紫外线吸收剂UV‑0在橡胶与氯磺化聚乙烯橡胶中配合较好,同时为了进一步提高该轮胎胎侧胶的耐臭氧老化性能及降低胶料的成本,加入了具有显著耐臭氧老化性能的高强力丁基复原胶。
