Provided are a laminated anti-vibration rubber and a rubber member having excellent flame retardancy, cold resistance, and durability. The laminated anti-vibration rubber (1) comprises a main shaft (2), an outer cylinder (3) which is arranged concentrically with respect to the axis (P) of the main shaft (2), an elastic part (4) which has a structure in which a plurality of elastic layers (12a, 12b, 12c, 12d, 12e) and one or a plurality of hard layers (13a, 13b, 13c, 13d) are alternately laminated in the radial inner-outer direction with respect to the axis (P) and is sandwiched between the main shaft (2) and the outer cylinder (3), and a coating layer (5) which covers at least the elastic layers (12a, 12b, 12c, 12d, 12e). The elastic layers (12a, 12b, 12c, 12d, 12e) contain natural rubber as a main component, and the coating layer (5) is configured from a rubber composition containing, as a main component, an isoprene rubber having higher flame retardancy than the elastic layers (12a, 12b, 12c, 12d, 12e).
本发明提供一种阻燃性、耐寒性、持久性优异的层叠型防振橡胶及橡胶部件。层叠型防振橡胶(1)包括:主轴(2)、相对于主轴(2)的轴心(P)呈同心状配置的外筒(3)、具有向相对于轴心(P)的径向内外方向交替层叠多个弹性层(12a、12b、12c、12d、12e)和一个或多个硬质层(13a、13b、13c、13d)的结构并夹设在主轴(2)与外筒(3)之间的弹性部(4)、以及至少覆盖弹性层(12a、12b、12c、12d、12e)的被覆层(5),弹性层(12a、12b、12c、12d、12e)含有天然橡胶作为主要成分,被覆层(5)由含有阻燃性比弹性层(12a、12b、12c、12d、12e)高的异戊二烯橡胶作为主要成分的橡胶组合物构成。
