Document Type and Number:
WIPO Patent Application WO/2023/190177
Kind Code:
A1
Abstract:
A purpose of the present invention is to provide: compositions for a vulcanization-bonded laminate which are for tenaciously bonding an epichlorohydrin rubber to a fluororubber; and a laminate obtained from the compositions. The compositions for a vulcanization-bonded laminate comprise stacked layers that are a rubber layer (A) formed from a composition for vulcanization bonding which comprises an epichlorohydrin rubber, a tri- to pentafunctional acrylate having no hydroxyl group, an epoxy resin, nickel dibutyldithiocarbamate, and a vulcanizing agent and a fluororubber layer (B) formed from a fluororubber composition at least containing a peroxide-based vulcanizing agent. From the compositions for a vulcanization-bonded laminate, a laminate is obtained in which the rubber layer (A) and the fluororubber layer (B) have been tenaciously bonded.
