Abstract

A semi-finished product or tire comprises a metal reinforcing element embedded in a rubber composition comprising a compound of formula (I): where X and Y represent, independently of one another, an alkali metal or alkaline earth metal cation.

Description

technical field [0001] The invention relates to a semi-finished product and a tire comprising a composition containing a corrosion inhibitor, and also to its use. Background technique [0002] Compositions known from the prior art for use in tires include natural rubber (such as diene elastomers), carbon black and / or silica as reinforcing fillers, vulcanization systems including sulfur, and various additives (including in particular corrosion inhibitor). [0003] The composition used to make the semi-finished product comprises metal reinforcing elements, such as metal cords, embedded in the rubber composition. During the use of the tire, corrosive agents such as water can come into contact with the metal reinforcing elements, penetrate them and corrode them, thus rapidly deteriorating their mechanical properties and their adhesion to the rubber composition. [0004] On the one hand, the corrosion inhibitor prevents the action of the corrosive agent by forming a protective ...
