VULCANIZABLE RUBBER COMPOSITION, METAL REINFORCED RUBBER CANVAS AND PROCESS TO IMPROVE METAL ADHERENCE PROPERTIES AND METAL ADHESION RETENTION BETWEEN A VULCANIZABLE RUBBER COMPOSITION AND REFERENCE ELEMENTS

摘要

Vulcanizable rubber compositions and articles such as tires having improved metal adhesion and metal adhesion retention to brass and brass-plated metallic reinforcement. The improvement comprises substituting at least about 10.0 parts by weight of a halogenated rubber for non-halogenated rubber present in the vulcanizable rubber composition. The non-halogenated rubber can be natural or synthetic or blends thereof. A method for improving the metal adhesion and metal adhesion retention between a vulcanizable rubber and brass or brass-plated metallic reinforcement includes the steps of blending at least about 10.0 parts by weight of a halogenated rubber with up to about 90.0 parts by weight of a vulcanizable rubber essentially free of other halogenated rubber and curing the blend of rubbers with the brass or brass-plated metallic reinforcement embedded therein.
