Problems solved by technology

However, in Patent Document 1 in which particulate carbon black is added and in Patent Document 3 in which a large amount of carbon black is added, extrusion molding is difficult because the viscosity of the compound is significantly increased, and the composition cannot be directly applied to wrapping wires and cables. cladding
In addition, in Patent Document 2, which uses sulfur as a vulcanizing agent, its heat resistance is poor, so its application to wire and cable covering materials is limited.
[0004] As a way to improve the slipperiness of electric wires and cables, it is usually a method of mixing solid lubricants such as graphite, molybdenum disulfide, tetrafluoroethylene resin, silicone resin, and lubricant in the composition of the coating material, but there are the following defects: When these substances are mixed, mechanical strength such as tensile strength will be greatly reduced

Abstract

The invention discloses a wire, a cable, and a composition which feature excellent wearing resistance performance, low friction, and good mechanical strength. The wire and cable are formed by wrapping the composition to the periphery of the conductors or wire core, wherein the composition is formed by dispersing the reinforced type filler within the scope of above 10 parts by mass and below 100 parts by mass relative to the elastomer of 100 parts by mass and further dispersing the fatty acid amide within the scope of above 3 parts by mass and below 200 parts by mass.

Description

technical field [0001] The present invention relates to electric wires, cables and compositions having excellent low friction properties in a sliding environment. Background technique [0002] Electric wires and cables such as rubber insulated flexible cables (cabtyre cables) pass through wire pipes, conduits, etc., or are dragged around during wiring and erection. In addition, when used, electric wires and cables may come into contact with each other or other members, and may be used while sliding. Therefore, covering materials for electric wires and cables are naturally required to have excellent wear resistance, and also low friction properties with good slipperiness (slipperiness). [0003] In order to improve wear resistance, as proposed in Patent Documents 1 to 3, carbon black is mixed with diene rubber and fatty acid amide (fatty acid amide) is added as a processing aid to improve processability. However, in Patent Document 1 in which particulate carbon black is add...
