Acrylic rubber composition and cross-linked product thereof
First Claim
1. An acrylic rubber composition comprising:
- an acrylic rubber;
a functionalized silicone oil; and
an aromatic polyamine, wherein;
the acrylic rubber is at least one compound selected from a carboxyl group-containing acrylic rubber, an epoxy group-containing acrylic rubber, and an active chlorine group containing acrylic rubber,the silicone oil is included in an amount of 0.3 to 30 parts by mass based on 100 parts by mass of the acrylic rubber and has a polydimethylsiloxane structure represented by Formula 1 and having at least one of binding sites α
, β
, and γ
bonded with a functional group and has a functional group equivalent of 1 to 100,000 (g/mol);

Abstract
Provided is an acrylic rubber composition including an acrylic rubber and a functionalized silicone oil. Here, the functionalized silicone oil preferably has a particular polydimethylsiloxane structure having at least one binding site bonded with at least one of a monoamino group, a diamino group, a polyether group, an epoxy group, an alicyclic epoxy group, a hydroxyl group, a thiol group, a carboxyl group, a hydrogen group (Si—H group), a methacryl group, a phenol group, an alkoxy group, an ester group, an amide group, an alkyl group, a fluoroalkyl group, and a diol group and has a functional group equivalent weight of 1 to 100,000 (g/mol). The composition is unlikely to be deteriorated even when it is exposed to high temperature for a long time and that has excellent heat resistance and a crosslinked product of the composition. The composition is unlikely to be deteriorated even when it is exposed to high temperature for a long time and that has excellent heat resistance and a crosslinked product of the composition.
