The invention relates to a rubber composition based on 20 phr to 100 phr of ethylene, a copolymer of a first 1, 3-diene, which is 1, 3-butadiene, isoprene or a mixture thereof, and a second 1, 3-diene of the formula CH2 = CR-CH = CH2, 0 phr to 80 phr of at least one diene elastomer, 10 phr to 100 phr of a plasticizing system, a reinforcing filler and a crosslinking system, wherein the symbol R represents a hydrocarbon chain having 3 to 20 carbon atoms, the ethylene units in the copolymer making up more than 50 mol% of the monomer units of the copolymer, the diene elastomer having a diene unit weight content of more than 50%, the plasticizing system comprises at least one plasticizing resin having a glass transition temperature higher than 20 DEG C and/or at least one plasticizer that is liquid at 23 DEG C. The invention also relates to an elastomer laminate and a rubber article, in particular a pneumatic or non-pneumatic tire, comprising such a composition.

    本发明涉及一种橡胶组合物,所述橡胶组合物基于:20phr至100phr的乙烯、第一1,3‑二烯和式CH2=CR‑CH=CH2的第二1,3‑二烯的共聚物、0phr至80phr的至少一种二烯弹性体、10phr至100phr的增塑体系、增强填料以及交联体系,所述第一1,3‑二烯为1,3‑丁二烯、异戊二烯或其混合物,其中符号R表示具有3至20个碳原子的烃链,所述共聚物中的乙烯单元占共聚物的单体单元的大于50摩尔%,所述二烯弹性体的二烯单元重量含量大于50%,所述增塑体系包含至少一种玻璃化转变温度高于20℃的增塑树脂和/或至少一种在23℃下为液体的增塑剂。本发明还涉及包含这种组合物的弹性体层压件和橡胶制品,特别是充气或非充气轮胎。
