METHOD FOR VULCANIZATION AND ADHESION OF RUBBER COMPOSITION WITH ARTICLE TO BE ADHERED BEING MADE OF BRASS OR PLATED WITH BRASS, REINFORCING MATERIAL FOR RUBBER ARTICLE, RUBBER-REINFORCING MATERIAL COMPOSITE, AND PNEUMATIC TIRE

摘要

A method for the vulcanization and adhesion of a rubber composition with an article to be adhered being made of brass or plated with brass, wherein a metal exhibiting a catalytic action to the vulcanization adhesion reaction is stably attached on the surface of brass via a silane coupling agent; a reinforcing material for a rubber which is produced by subjecting a steel filament plated with brass or a steel cord composed of a plurality of the plated steel filaments being twisted to a surface treatment with a solution of a silane coupling agent containing the above metal; and a rubber-reinforcing material composite and a pneumatic tire which use the above reinforcing material for a rubber. The above method can improve the adhesiveness of a rubber composition with an article to be adhered being made of brass or plated with brass, and the reinforcing material is improved in the adhesiveness thereof with a coating rubber.
