AI Technical Summary

Problems solved by technology

Because of the limited bending strength and small elongation, electrical connections over relatively large distances via otherwise commonly used metal conductors become very difficulty
There is no reliable way to achieve conduction of electrical current for energy supply or for signal transmission in currently available conductive rubber compounds

Embodiment Construction

[0018] figure 1 A cross-section through a conductive cord 1 consisting of an externally sheathed reinforcing core 2 is shown. The reinforcing core 2 may be a monofilament, a yarn, or a cord composed of a plurality of yarns. figure 1 A yarn made of a multitude of filaments 3 is shown. The reinforcing core 2 consists of a non-metallic textile material (eg rayon, polyester, polyamide, or aramid) and is therefore non-conductive. The reinforcing core 2 can also be composed of various non-metallic materials.

[0019] The cord 1 has a multilayer coating 4 which is figure 1 The embodiment shown in has two layers. The layer 5 positioned directly on the reinforcing core 2 is electrically conductive and may consist of carbon black, graphite powder, or carbon nanotubes, or of an elastomer-containing material based, by way of example, on latex Or based on a suspension comprising another elastomer and comprising electrically conductive particles which ensure that layer 5 is electricall...

Abstract

A cord (1) for use in elastomeric products such as pneumatic vehicle tires, the cord comprising a reinforcing core (2) made of a non-conductive material surrounded by a conductive layer (5) cover. An additional electrically insulating layer (6) is arranged on the electrically conductive layer (5), which covers the electrically conductive layer (5).

Description

technical field [0001] The invention relates to a cord for use in elastomeric products, preferably pneumatic tires, comprising a reinforcing core made of a non-conductive material and provided with a conductive coating. The invention further relates to an elastomeric product, in particular a pneumatic tire, comprising at least one such cord. Background technique [0002] In elastomeric products (eg, in pneumatic tires (eg carcasses, belts, etc.)) reinforcement systems embedded in rubber compounds are often used. Non-conductive materials are often used for reinforcement systems, examples being polyester, rayon, polyamide, aramid, and hybrid cords made of the materials mentioned above. The material and structure of the reinforcement system are selected so as to meet the requirements placed on the relevant components during the tire's service. Furthermore, the reinforcement system is usually provided with a coating, especially an adhesion promoter, which is likewise non-condu...
