RESIN-METAL COMPOSITE MATERIAL, METHOD FOR PRODUCING THE SAME AND TIRE

摘要

PROBLEM TO BE SOLVED: To provide a resin-metal composite material excellent in adhesion between a resin material and a metal steel wire, a method for producing the same, and a tire equipped with the resin-metal composite material.

SOLUTION: The resin-metal composite material has: the metal steel wire having a surface with a lubricant coating weight of ≤1.5 atom% and a rust preventive coating weight of <3.0 atom%; and a resin material layer formed on the surface via a silane coupling agent. The resin-metal composite material can be produced by the method for producing the resin-metal composite material comprising: a surface treatment step of applying a treatment liquid to the surface of the metal steel wire, wherein the treatment liquid contains at least an acid and has a pH value of <7; and a resin material layer formation step of applying the silane coupling agent to the surface of the surface-treated metal steel wire and subsequently applying the resin material to the same.
