Composition for vulcanization bonding, compositions for vulcanization-bonded laminate, and laminate obtained from said compositions

Abstract

The present invention aims to provide a composition for a vulcanization-bonded laminate in which an epichlorohydrin rubber can be strongly bonded to a fluororubber, as well as a laminate produced from the composition. It has been found that a composition for a vulcanization-bonded laminate which includes a rubber layer (A) formed from a vulcanization bonding composition at least containing an epihalohydrin rubber, a hydroxyl group-free tri- to penta-functional acrylate, an epoxy resin, nickel dibutyldithiocarbamate, and a vulcanizing agent, and a fluororubber layer (B) formed from a fluororubber composition containing at least a peroxide vulcanizing agent, and in which the rubber layer (A) and the fluororubber layer (B) are stacked can be used to produce a laminate in which the rubber layer (A) is strongly bonded to the fluororubber layer (B).
