Abstract
Official abstract text for this publication.
An object of the present invention is to provide an ethylene-acrylic rubber composition that is excellent in the compression set and also in the crosslinking bonding even when no secondary crosslinking is caused therein, an ethylene-acrylic rubber produced by causing primary crosslinking in the composition, a rubber metal composite formed by bonding the ethylene-acrylic rubber and a metal with each other, and a bonded piston sealing including the rubber metal composite. The object is achieved by an ethylene-acrylic rubber composition including 1 to 7 PHR by weight of calcium hydroxide relative to 100 PHR by weight of a binary ethylene-acrylic rubber polymer that includes ethylene and an acrylic acid ester, an ethylene-acrylic rubber produced by causing peroxide-crosslinking by primary crosslinking in the ethylene-acrylic rubber composition, a rubber metal composite formed by crosslinking-bonding the ethylene-acrylic rubber and a metal with each other bonded with the primary crosslinking, and a bonded piston sealing including the rubber metal composite.

1 . An ethylene-acrylic rubber composition comprising 1 to 7 PHR by weight of calcium hydroxide and organic peroxide relative to 100 PHR by weight of a binary ethylene-acrylic rubber polymer that comprises ethylene and an acrylic acid ester. 2 . The ethylene-acrylic rubber composition according to claim 1 , comprising 1 to 3 PHR by weight of the calcium hydroxide and organic peroxide relative to 100 PHR by weight of the binary ethylene-acrylic rubber polymer. 3 . The ethylene-acrylic rubber composition according to claim 1 , wherein the acrylic acid ester is methyl acrylate. 4 . An ethylene-acrylic rubber formed by causing peroxide-crosslinking by primary crosslinking in the ethylene-acrylic rubber composition according to claim 1 . 5 . A rubber metal composite formed by crosslinking-bonding the ethylene-acrylic rubber according to claim 4 and a metal with each other bonded with the primary crosslinking. 6 . A bonded piston sealing comprising the rubber metal composite according to claim 5 . 7 . A manufacturing method of an ethylene-acrylic rubber formed by causing peroxide-crosslinking by primary crosslinking in the ethylene-acrylic rubber composition according to claim 1 .
