METHOD FOR VULCANIZATION-ADHERING RUBBER COMPOSITION TO ADHERENT OF BRASS OR PLATED WITH BRASS, REINFORCING MEMBER FOR RUBBER ARTICLE, RUBBER-REINFORCING MEMBER COMPOSITE AND PNEUMATIC TIRE

摘要

This invention relates to a method for vulcanization-adhering a rubber composition to an adherent made from a brass or plated with a brass in the vulcanization adhesion between the rubber composition and the adherent made from the brass or plated with the brass by stably adhering a metal having a catalytic action to vulcanization adhesion reaction to the surface of the brass through a silane coupling agent as well as a reinforcing member for rubber article having an adhesion property to a coating rubber by subjecting a steel filament plated with a brass or a steel cord formed by twisting a plurality of such steel filaments to a surface treatment with a metal-containing silane coupling agent solution, and a rubber-reinforcing member composite and a pneumatic tire using such a reinforcing member for rubber article.
