However, in particular,
When an EPDM is used in a liquid-filled type engine mount having a liquid chamber having a vibration-proof rubber body as a chamber wall, the vibration-proof rubber body made of EPDM is bonded to the outer surface thereof. There is a drawback that the adhesiveness with the metal connecting member is insufficient. It is considered that this is because the enclosed liquid penetrates into the anti-vibration rubber body and acts on the adhesive interface to reduce the adhesive force, and improvement of the adhesiveness is a problem.

The filled liquid usually contains ethylene glycol, diethylene glycol and water, which penetrates into the rubber body 1 to reach the adhesive interface and acts on the adhesive to reduce its adhesive strength. On the other hand, in the configuration of the present invention,
The undercoat adhesive layer 7 containing a resorcin resin as a main component is firmly bonded to the metal surface by three-dimensional cross-linking, prevents permeation of the enclosed liquid, and maintains high adhesive strength. On the other hand, the top coat adhesive layer 8 containing chlorosulfonated polyethylene as a main component,
It is considered that the adhesive strength with a heat resistant rubber material such as EPDM is excellent, and a similar strong bond is formed with the rubber body 1 to prevent the adhesive strength from being lowered. In this way, by using two adhesive layers and using an adhesive that exhibits extremely strong adhesiveness at the interface between metal and rubber, a decrease in adhesive strength due to the permeation of the enclosed liquid is suppressed, and durability is improved. Let Further, the heat resistance is improved by forming the rubber body 1 with a rubber material such as EPDM or CR.

As is clear from Table 1, in the adhesive compositions of Examples 1 and 2, both the initial adhesive strength and the adhesive strength after immersion in the encapsulating liquid show high values. Further, it is understood that the broken state is mainly rubber breakage, and the adhesive layer and the rubber body 1 or the holding plates 91 and 92 are firmly bonded at the bonding interface. On the other hand, in Comparative Example 1, RC fracture occurs at an adhesive strength of 0 MPa in the initial state, indicating that the resorcin resin adhesive alone does not have sufficient adhesive force. Further, in both Comparative Examples 1 and 2, the adhesiveness after immersion in the enclosing liquid was remarkably reduced, and particularly in Comparative Example 1, the adhesive surface was completely peeled off and the test was impossible. in this way,
By adopting the adhesive composition of the present invention, it is possible to improve the adhesiveness, prevent deterioration of the adhesiveness due to contact with the enclosed liquid, and significantly improve heat resistance and durability.
