[0004] However, the fluororesin and rubber have poor adhesiveness and cannot be firmly bonded. Conventionally, an isocyanate-based adhesive is known as an adhesive for a fluororesin, but this adhesive has good static adhesiveness, but is inferior in dynamic adhesiveness, and is subject to bending deformation such as bending. It was not easy to peel off and durable adhesive strength was obtained.

In the method for producing an adhesive composite of the present invention,
The modified NBR rubber composition is subjected to an adhesive treatment in an unvulcanized state. When it is unvulcanized, when it is vulcanized under heating, the unvulcanized modified NBR rubber composition undergoes a cross-linking reaction and adheres firmly to the fluororesin and between the rubber compositions. I will be. When using this modified NBR rubber composition as an adhesive, it is desirable to use it in the form of a film having a thickness of 10 μm to 1.0 mm. By setting the thickness to 10 μm or more, the adhesive strength can be increased. However, since the adhesive strength becomes saturated at a thickness of 1.0 mm or more, it is economical to set the upper limit to 1.0 mm.

When the rubber composition containing CHC as a main component is also subjected to the bonding treatment, each is used in an unvulcanized state. This is because when vulcanized, the adhesion to the modified NBR rubber composition decreases. The bonding conditions are such that the unvulcanized modified NBR rubber composition and the rubber composition containing IIR, NBR, CSM, ACM, and CHC as main components are each vulcanized, preferably at 160 to 180 ° C and 15 to 15 ° C. It is good to heat under a press for 30 minutes.
