[0054] Brass-plated (Cu: 63% by mass, Zn: 37% by mass) steel wires were twisted to form a steel cord of 1×5 structure. Next, the steel cord was washed in a 10 g / L cobalt acetate aqueous solution (pH 6.0) for 30 seconds and dried at 50° C. for 1 minute. The steel cords were then arranged in parallel to each other, and covered with each rubber composition having the formulation described in Table 1 from both the upper and lower directions and vulcanized under the conditions described in Table 1. Samples were thus prepared.

The present invention aims to provide a steel cord-rubber composite that is, even when a rubber composition constituting coating rubber does not contain cobalt salt, excellent in adhesion to a steel cord and capable of suppressing a decrease in modulus. The steel cord-rubber composite according to the present invention is constituted by using the steel cord coated with a rubber composition containing organic acid metal salt containing 10 mass % or less of free acid.
Description
technical field [0001] The present invention relates to a steel cord-rubber compound, and more particularly, to a compound having excellent adhesion to steel cords and capable of suppressing a decrease in modulus even when a rubber composition constituting a covering rubber does not contain a cobalt salt Steel cord-rubber compound. Background technique [0002] Rubber products such as automobile tires, conveyor belts, rubber hoses, etc. employing a steel cord-rubber compound require special strength, and for the purpose of improving strength and durability by reinforcing rubber, the rubber products are made of rubber covered with covering rubber by using The steel cord-rubber composite composed of metal reinforcing members such as steel cords and the like. Here, in order to provide high reinforcing effect and win credibility, the steel cord-rubber compound needs to have stable and strong adhesiveness between the covering rubber and the metal reinforcing member. [0003] In...
