ADHESIVE COMPOSITION FOR ORGANIC FIBER CORD, AND RUBBER REINFORCING MATERIAL, TIRE AND ADHERING METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an adhesive composition for an organic fiber cord, which does not contain resorcin and formalin, and is excellent in adhesion and an environment, particularly in a work environment, and to provide a rubber reinforcing material, a tire and an adhering method using the same.;SOLUTION: In the adhesive composition for the organic fiber cord, which contains a blocked isocyanate compound (A), an epoxy compound (B) and a rubber latex (C), the rubber latex (C) comprises: a copolymer rubber latex (a) of 50 to 90 pts.mass (in terms of solid content), which is obtained by emulsion polymerization of 35 to 75 mass% of a butadiene-based monomer, 15 to 30 mass% of a vinylpyridine-based monomer and 10 to 55 mass% of a styrene-based monomer; and a copolymer rubber latex (b) of 10 to 50 pts.mass (in terms of solid content), which is obtained by emulsion polymerization of 3 to 20 mass% of a butadiene-based monomer, 75 to 96.9 mass% of a styrene-based monomer, 0.1 to 10 mass% of ethylenic unsaturated carboxylic acid and 0 to 20 mass% of other copolymerizable monomers, and has a glass-transition temperature of 40 to 90°C.;COPYRIGHT: (C)2013,JPO&INPIT
