PROBLEM TO BE SOLVED: To provide a method for producing a rubber product including a thick wall rubber composition or its laminated material comprising decreasing the temperature difference between its surface and the inside, reducing the unevenness of cross-linking density and also the unevenness of hardness, and further shortening the time for cross-linking (vulcanization). SOLUTION: This method for producing the rubber product is provided by blending a 10 to 60 pts.mass co-crosslinking agent, a 0.1 pt.mass to 6 pts.mass organic peroxide and a 5 to 50 pts.mass metallic magnetic powder based on 100 pts.mass of a base rubber to form a rubber composition and at least partially crosslinking the composition by electromagnetic induction heating. The co-crosslinking agent is preferably anα,β-unsaturated carboxylic acid or anα,β-unsaturated carboxylic acid metal salt. COPYRIGHT: (C)2009,JPO&INPIT |
