Embodiment 1
[0270] This example shows the improved adhesion provided by the composition according to the invention relative to the control composition.
[0271] Table 2 shows the results of the adhesion tests carried out on the control samples and on the samples according to the invention.
[0272] Not only in the case of wire elements made of brass, but also in the case of wire elements made of zinc, steel or bronze, the composites according to the invention exhibit values well above 100 in the adhesion test, Has greatly improved tear-out resistance.
[0273] Improved properties of the composites were observed without any vulcanization step.

Abstract
The invention relates to a rubber composition based on at least one elastomer comprising epoxide functions, a crosslinking system comprising a carboxylic polyacid and an imidazole and at least one phenolic compound, the aromatic ring of said phenolic compound being substituted with at least one carboxyl group, a hydrogencarbonyl group, an amino group or an aminoalkyl radical.
Description
technical field [0001] The present invention relates to elastomer-based rubber compositions comprising epoxy functional groups, composites comprising said compositions, and tires comprising said compositions or said composites. Background technique [0002] A tire reinforcement ply usually consists of a rubber compound and reinforcing cables, usually metallic and covered with brass on the surface. The bond between the rubber compound and the metal cable is produced by the phenomenon of vulcanization of the brass-coated surface of the cable. However, under the influence of humidity, temperature or corrosive components, the resulting mesophase may change. [0003] The adhesion function usually utilizes a specific formulation of the rubber compound, which in particular requires high levels of sulfur and zinc oxide, small amounts of stearic acid, the presence of cobalt salts, and the use of delayed-action accelerators. [0004] Therefore, there is a continuing focus of tire ma...
