Abstract
Official abstract text for this publication.
A ready-for-use metal reinforcer, for example, of the wire or cord type, made of brass-coated carbon steel, is capable of adhering directly by vulcanization to a matrix of unsaturated rubber such as natural rubber. The surface of the reinforcer is provided with nanoparticles of at least one sulfide of a metal chosen from cobalt, copper, iron, zinc and the alloys comprising at least one of these elements. Such a reinforcer can be used as the reinforcing element of a finished article made of rubber, such as a tire.
First claim
Opening claim text (preview).
The invention claimed is: 1. A ready-for-use metal reinforcer capable of adhering by vulcanization to an unsaturated rubber matrix, wherein the ready-for-use metal reinforcer comprises a surface provided with nanoparticles of at least one sulfide of a metal selected from the group consisting of cobalt, copper, iron, zinc, and alloys comprising at least one of these elements. 2. The ready-for-use metal reinforcer according to claim 1 , wherein the metal is selected from the group consisting of copper, zinc and alloys comprising at least one of these elements. 3. The ready-for-use metal reinforcer according to claim 2 , wherein the nanoparticles are nanoparticles of zinc sulfide or copper sulfide. 4. The ready-for-use metal reinforcer according to claim 1 further comprising a wire, an assembly of wires, a cord, a film or a plate. 5. The ready-for-use metal reinforcer according to claim 4 comprising a wire or a cord. 6. The ready-for-use metal reinforcer according to claim 1 , wherein the metal reinforcer is made of steel. 7. The ready-for-use metal reinforcer according to claim 6 , the steel being a carbon steel. 8. The ready-for-use metal reinforcer according to claim 6 , wherein the steel is coated with brass. 9. A finished article made of rubber comprising the ready-for-use metal reinforcer according to claim 1 as a reinforcing element. 10. The finished article according to claim 9 , wherein the finished article is a tire.
