METHOD FOR PRODUCING BONDED PRODUCT OF ETHYLENE-alpha-OLEFIN RUBBER COMPOSITION WITH FIBER AND DRIVING BELT

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a bonded product of an ethylene-α-olefin rubber composition with a fiber in which an ethylene-α-olefin rubber composition can favorably be bonded to a woven fabric such as a fiber cord which becomes a core wire for driving belt and a cover canvas and to provide a driving belt. SOLUTION: The method for producing the bonded product of the ethylene-α-olefin rubber composition with the fiber comprises carrying out over coat treatment of the fiber with a rubber paste obtained by compounding 100pts.wt. ethylene-α-olefin-diene copolymer rubber latex having 8-20% diene content with 2-20pts.wt. fatty acid or/and fatty acid derivative and 5-35pts.wt. isocyanate compound as a processing aid and then bringing the treated fiber into close contact with an unvulcanized rubber composition of ethylene-α-olefin rubber and vulcanizing the rubber composition.
