橡胶组合物
本发明涉及一种橡胶组合物，该橡胶组合物基于至少一种具有玻璃化转变温度TgE1的非官能化二烯弹性体E1、具有玻璃化转变温度TgE2的第二官能化二烯弹性体E2、能够与官能化二烯弹性体E2相互作用的增强填料、以及交联体系，其中：玻璃化转变温度TgE1不低于‑50℃，玻璃化转变温度TgE2满足数学关系式TgE2≤TgE1–23℃，以及非官能化二烯弹性体E1的含量大于或等于50phr。本发明还涉及包含至少一种如上所限定的组合物的胎面和/或充气或非充气轮胎。
A rubber composition is based on at least one non-functionalized first diene elastomer E1 having a glass transition temperature TgE1, one functionalized second diene elastomer E2 having a glass transition temperature TgE2, a reinforcing filler capable of interacting with the functionalized diene elastomer E2 and a crosslinking system, in which: the glass transition temperature TgE1 is above or equal to -50° C., the glass transition temperature TgE2 satisfies the mathematical relationship TgE2 ≤ TgE1-23° C., and the content of the non-functionalized diene elastomer E1 is greater than or equal to 50 phr. A tread and/or a pneumatic or non-pneumatic tire may comprise at least one composition as defined above.
