Abstract: A threadlike metallic or metallized reinforcer, for example a thread, film, tape or cord made of carbon steel, at the periphery of which is positioned a layer of metal referred to as “surface metal” chosen from copper, nickel and copper/nickel alloys, is characterized in that this surface metal layer is itself coated, at least in part, with at least one layer of graphene; preferably, there is grafted, to this graphene, at least one functional group which can crosslink to a polymer matrix. This reinforcer of the invention is effectively protected from corrosion by virtue of the graphene present at the surface; advantageously, it can be adhesively bonded directly, without adhesion primer or addition of metal salt, to an unsaturated rubber matrix, such as natural rubber, by virtue of the possible functionalization of this graphene.

Abstract: A process for depositing, with forward progression, graphene on the surface of a metallic or metallized continuous reinforcer, at the periphery of which is positioned a layer of surface metal chosen from copper, nickel and copper/nickel alloys, comprises at least one stage of flame spray pyrolysis (“FSP”), under a reducing atmosphere, of a carbon precursor which generates, in the flame, at least one carbon-based gas such as carbon monoxide which is sprayed onto the surface of the reinforcer in forward progression, and is decomposed thereon to form one or more graphene layers at the surface of the surface metal; an additional stage of graphene functionalization makes it possible to adhere the reinforcer to a polymer matrix such as rubber.

The polymer comprises base units comprising at least a sub-unit of formula —X1—CO—NH— in which X1 respectively represents O or S, and additional units comprising at least a secondary alcohol function and a thioether function in the ? position relative to the alcohol function. The polymer can be used as an adhesion primer for the adhesive bonding of a substrate, for example glass or metal, to an unsaturated rubber, or as a corrosion-resistant protective coating for a metal substrate. A metal reinforcer, such as wire, cord, film or plate, can be coated with the polymer.

Abstract: 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.

Abstract: The surface of a body, in particular a metal reinforcer, at least the surface of which comprises a layer of metal referred to as surface metal capable of forming sulphides, is sulfurized. The metal can be chosen from copper, zinc and their alloys. The process comprises at least one stage of flame spray pyrolysis (FSP) of a sulphur-donating precursor, for example, thiophene, which generates hydrogen sulphide in the flame. The metal bodies or reinforcers thus treated can be directly adhesively bonded, without adhesion primer or addition of metal salt, such as a cobalt salt, to matrices of unsaturated rubber such as natural rubber.

Abstract: A polyurea comprises at least urea base units of formula —NH—CO—NH— and additional units. The additional units comprise at least, on the one hand, a secondary alcohol functional group and, on the other hand, an ether, thioether or secondary amine functional group in the alpha position with respect to the secondary alcohol functional group.
