<p>PROBLEM TO BE SOLVED: To provide a rubber laminate enhanced in adhesive strength at a high temperature and under a high strain by optimizing the composition of an adhesive rubber arranged between a hydrogenated NBR composition and a general purpose dienic rubber. SOLUTION: The adhesive rubber composition comprises 100 pts.wt. of a rubber comprising 50-85 pts.wt. of at least one dienic rubber selected among natural rubbers, polyisoprene rubbers, polybutadiene rubbers and conjugated diene/aromatic vinyl copolymer rubbers and 15-50 pts.wt. of an ethylenically unsaturated nitrile/conjugated diene-based, highly saturated rubber containing at most 30 wt.% of a conjugated diene unit, and, incorporated therewith, 10-60 pts.wt. of zinc methacrylate, 0.3-10 pts.wt. of an organic peroxide and 5-50 pts.wt. of a co-crosslinking agent bearing any of an acrylic group, a methacrylic group and an allyl group and in a liquid state at room temperature.</p> |
