The invention discloses an ultralow-temperature high-grip snow tire rubber material and a preparation method thereof, 50-60 parts of solution polymerized styrene-butadiene rubber, 20-30 parts of butadiene rubber and 10-30 parts of liquid isoprene rubber are adopted as base rubber, and modified nylon short fibers are added, and the ultralow-temperature high-grip snow tire rubber material is prepared from 50-60 parts of solution polymerized styrene-butadiene rubber, 20-30 parts of butadiene rubber and 10-30 parts of liquid isoprene rubber. According to the invention, the modified nylon short fiber is used as a main raw material, then the main raw material, the white carbon black, the silane coupling agent, the carbon black, the modified nylon short fiber, the anti-aging agent, the protective wax, the accelerant and the sulfur jointly support the tire rubber material, the hardness of a tire prepared from the rubber material basically does not change at-20 DEG C, and the weight is not changed after the tire is stored for 60 days at 60 DEG C, which indicates that the rubber material basically does not volatilize low-molecular substances, and the hardness can be kept stable.
本发明公开了一种超低温高抓地雪地轮胎橡胶胶料及其制备方法,采用溶聚丁苯橡胶、顺丁橡胶、液体异戊橡胶为基胶,并添加改性尼龙短纤维,其中溶聚丁苯橡胶50‑60份,顺丁橡胶20‑30份,液体异戊橡胶10‑30份,然后与白炭黑、硅烷偶联剂、炭黑、改性尼龙短纤维、防老剂、防护蜡、促进剂、硫磺共同支撑轮胎橡胶胶料,该胶料制备的轮胎在‑20℃下硬度基本无变化,在60℃下停放60天重量无变化,说明胶料基本没有低分子物质挥发,在此可以保持硬度稳定。
