<p>PURPOSE:To enhance the adhesion between metallic mandrel and rubber layer by a method wherein rubber covering layer is made of rubber composition containing 100 pts. wt. of rubber component, which contains 50 wt.% or more of highly saturated copolymer rubber, and 10-40 pts. wt. of zincate. CONSTITUTION:The rubber roll concerned consists of metallic core (iron core) 10 and at least one or more layers of rubber covering layers 11 and 12. The rubber covering layers 11 and 12 are vulcanized rubber layer composed of rubber composition, which contains ethylenic unsaturated nitrile-conjugate diene- based highly saturated copolymer rubber having 25 wt.% of content of conjugated diene unit in polymer chain. In addition, at least the rubber covering layer 11, which comes into contact with the metallic core 10, is vulcanized rubber layer composed of rubber composition, which contains 100 pts. wt. of rubber component containing 50wt.% or more of highly saturated copolymer rubber and 10-40 pts. wt. of zincate.</p> |
