PROBLEM TO BE SOLVED: To concretely clarify procedures of vulcanization adhesion of a fluororubber with a synthetic rubber other than fluororubbers, e.g. NBR and chloroprene rubbers, thereby provide a vulcanization-adhered laminate in which a fluororubber and a synthetic rubber are vulcanization-adhered firmly, without using a means of preventing scorching associated with usage of DBU, DBN, and the like.SOLUTION: The vulcanization-adhered laminate includes: a fluororubber layer and a layer including a synthetic rubber, vulcanization-adhered together. The synthetic rubber layer before the vulcanization adhesion includes (1) an organic peroxide, (2) silica, (3) an organic phosphonium salt, (4) a maleic acid anhydride modified polybutadiene and (5) magnesium oxide. |
