A cross-linkable nitrile rubber composition contains a carboxyl group-containing highly saturated nitrile rubber (A), a resin (B), and a polyamine cross-linking agent (C). The content of the carboxyl group-containing highly saturated nitrile rubber (A) is 30 parts by weight or more with respect to 100 parts by weight of the total amount of the carboxyl group-containing highly saturated nitrile rubber (A) and the resin (B). The cross-linkable nitrile rubber composition is obtained by performing kneading at a temperature equal to or higher than the melting point of the resin (B).
一种可交联丁腈橡胶组合物含有含羧基的高饱和丁腈橡胶(A)、树脂(B)和多胺交联剂(C)。相对于含羧基的高饱和丁腈橡胶(A)和树脂(B)总量的 100 重量份,含羧基的高饱和丁腈橡胶(A)的含量为 30 重量份或以上。可交联丁腈橡胶组合物是通过在等于或高于树脂(B)熔点的温度下进行捏合获得的。
