A rubber composition comprising a rubber, a filler and a diamide compound represented by the formula:
wherein X is hydrogen, alkyl of 1 to 18 carbon atoms, alkoxy of 1 to 18 carbon atoms, alkanoyl of 2 to 19 total carbon atoms, amino, nitro, cyano, hydroxy, carboxy or halogen, and n is an integer of 2 to 12. This rubber composition is increased in its loss factor and is useful for tires and rubber vibration isolators. For example, the resulting tires prepared from the rubber composition are improved in their gripping performance.
一种橡胶组合物,由橡胶、填料和二酰胺化合物组成,二酰胺化合物由式表示:
其中 X 是氢、1 至 18 个碳原子的烷基、1 至 18 个碳原子的烷氧基、2 至 19 个碳原子的烷酰基、氨基、硝基、氰基、羟基、羧基或卤素,n 是 2 至 12 的整数。这种橡胶组合物的损耗因子增加,适用于轮胎和橡胶隔振器。例如,用该橡胶组合物制备的轮胎可提高抓地性能。
