The invention discloses a high-damping shock-absorbing material for automobile body suspension and a preparation method and application thereof. The high-damping shock-absorbing material for automobile body suspension comprises a raw rubber system and nitrine formate. The raw rubber system comprises natural rubber, isobutylene-isoprene rubber and high-activity polyisobutylene rubber, and the content of alpha-terminal double bonds of the high-activity polyisobutylene rubber is not lower than 60%. The high-damping shock-absorbing material has the advantages of high damping property, shock-absorbing durability, low attenuation property, better fatigue durability, dimensional stability and the like, can ensure the damping shock-absorbing property under the dynamic condition of a vehicle when being used for vehicle body suspension, greatly improves the fatigue durability property, and delays the performance attenuation caused by product deformation.a The service life of the product is guaranteed, and meanwhile the comfort of the whole vehicle is improved.

    本发明公开了汽车车身悬置用高阻尼减震材料及其制备方法和应用。该汽车车身悬置用高阻尼减震材料包括生胶体系和叠氮甲酸酯,生胶体系包括天然橡胶、异丁烯‑异戊二烯橡胶和高活性聚异丁烯橡胶,高活性聚异丁烯橡胶的α‑末端双键含量不低于60%。该高阻尼减震材料兼具高阻尼特性、减震耐久和低衰减特性,以及较好的疲劳耐久性和尺寸稳定性等优点,将其用于车身悬置时能保证车辆动态情况下的阻尼减震特性,同时大大提升疲劳耐久特性,延缓由于产品变形导致的性能衰减,在保证产品使用寿命的同时,提升整车舒适性。
