Rubber-resin laminate

摘要

Disclosed is a vulcanized rubber laminate, wherein a thermoplastic resin layer and an unvulcanized epichlorohydrin rubber composition layer containing a specific maleimide compound, vulcanizing agent, and acid acceptor are heated and bonded. Specifically disclosed is a laminate configured by heating and bonding an unvulcanized epichlorohydrin rubber composition layer (A) and a thermoplastic resin (B), wherein the unvulcanized epichlorohydrin rubber composition contains: an epichlorohydrin rubber (a), a compound containing one or more maleimide group within the molecule (b), a vulcanizing agent (c), and an acid acceptor (d).

主权项

1. A laminate comprising (A) an unvulcanized epichlorohydrin-based rubber composition layer and (B) a thermoplastic resin layer,
wherein (A) the unvulcanized epichlorohydrin-based rubber composition and (B) the thermoplastic resin layer are heated to bond them together and to vulcanize (A) the unvulcanized epichlorohydrin-based rubber composition, and the unvulcanized epichlorohydrin-based rubber composition (A) contains the following (a) to (d): (a) an epichlorohydrin-based rubber, (b) a compound having one or more maleimide groups in the molecule, (c) a vulcanizing agent, said vulcanizing agent (c) containing at least one kind of a vulcanizing agent selected from a quinoxaline-based vulcanizing agent a thiourea-based vulcanizing agent, a triazine-based vulcanizing agent and a bisphenol-based vulcanizing agent, and (d) an acid acceptor.
