Provided are a laminate body, a cross-linked product, and a molded member superior in interlayer adhesiveness. An acrylic elastomer layer 11 is prepared from an acrylic elastomer composition containing an epoxy group-containing acrylic elastomer as major component, an onium salt in an amount of 1 to 5 parts by mass and a polyol compound in an amount of 1 to 8 parts by mass with respect to 100 parts by mass of the acrylic elastomer, and a fluorine-based elastomer layer 12 is prepared from a fluorine-based elastomer composition containing a polyol crosslinking agent. The acrylic elastomer layer 11 and the fluorine-based elastomer layer 12 are laminated, to give a laminate body 1. The laminate body 1 is cross-linked, to give a cross-linked product or a molded member.

Provided are an acrylic elastomer superior in adhesiveness to a fluorine-based elastomer, an acrylic elastomer composition containing the same, its laminate, and its crosslinked product and a molded article therefrom. Iodine groups are introduced as crosslinking groups into an acrylic elastomer to an iodine content of 0.1 to 2 mass % with respect to the total mass of the elastomer. In addition, 1 to 7 parts by mass of an organic peroxide and 1 to 5 parts by mass of an onium salt were blended with 100 parts by mass of the acrylic elastomer, to give an acrylic elastomer composition. Further, an acrylic elastomer layer of the acrylic elastomer composition is laminated with a fluorine-based elastomer layer of a fluorine-based elastomer composition mainly containing of a fluorine-based elastomer having iodine groups as crosslinking groups, to give a laminate. The laminate is then crosslinked to give a crosslinked product and a molded article.
摘要:
Provided is a laminate having elastomer layers tightly bonded to each other. The laminate according to the present invention 1 has an acrylic elastomer layer 11 and a fluorine elastomer layer 12 that are bonded to each other. The acrylic elastomer layer 11 is made of an acrylic elastomer composition having an epoxy group-containing acrylic elastomer and an onium salt added and the fluorine elastomer layer 12 is made of a fluorine elastomer composition having a fluorine elastomer and a polyol crosslinking agent added. In the laminate 1, the elastomer layers are bonded tightly to each other even without any surface treatment.
