In order to specifically ascertain a vulcanization-adhesion formula for a fluororubber and a synthetic rubber not including a fluororubber such as an NBR or a chloroprene rubber, and thereby provide a vulcanization-adhered laminate in which the fluororubber and the synthetic rubber are solidly adhered by vulcanization without employing scorch preventing means associated with the use of DBU, DBN, and the like, a vulcanization-adhered laminate is disclosed in which a fluororubber layer and a synthetic rubber-containing layer are adhered by vulcanization, and the synthetic rubber layer prior to the vulcanization-adhesion includes (1) to (5): (1) organic peroxide, (2) silica, (3) organic phosphonium salt, (4) maleic anhydride-modified polybutadiene, and (5) magnesium oxide. |
