RUBBER COMPOSITIONS AND ARTICLES THEREOF HAVING IMPROVED METAL ADHESION RETENTION

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.
