Method for making laminate

摘要

A method of insert molding comprises placing in a first mold a curable rubber composition comprising a reactive species; placing on a surface of the rubber composition a first thermoplastic material in a film or layer comprising a group reactive with the reactive species of the rubber composition; curing the rubber composition in the mold to form a first molded article of cured rubber having a first thermoplastic material layer covalently bonded through reactive of the reactive species and the group; placing the first molded article as an insert into a second mold, the cured rubber contacting an inside surface of the second mold and the thermoplastic layer facing into the second mold cavity; closing the second mold and injecting into the second mold a second thermoplastic material that to form a second molded article comprising the first molded article thermally welded and/or covalently bonded to the second thermoplastic material.

1. A method of preparing a molded article, comprising:
placing in a first mold a curable rubber composition; placing on a surface of the rubber composition a layer comprising a first thermoplastic material with unsaturated carbon-carbon bonds; curing the rubber composition in the first mold to form a first molded article with the first thermoplastic material covalently bound to the cured rubber composition; placing the first molded article into a second mold, the layer facing an inside cavity of the second mold; closing the second mold and injecting into the second mold a second thermoplastic material to form a second molded article with the first thermoplastic material thermally bound to the second thermoplastic material.
