Problems solved by technology

[0002] In the prior art, the cables are often arranged in a unified manner. Therefore, when it is necessary to add a cable or remove a certain cable in a pile of cables, the friction between the cables greatly increases the difficulty of construction. At the same time, the sheath and the sheath The friction between the sheaths is also a hidden danger to the safety of the cable itself, because if the sheath is damaged due to local friction, the entire cable may be damaged and cannot be used, and it often needs to be reinstalled. The more prominent the place

Abstract

The invention relates to the technical field of cable production and processing, and in particular relates to a lubricating wear-resisting cable outer sheath material. According to the technical scheme, the lubricating wear-resisting cable outer sheath material is prepared from the following materials in parts by weight: 20-30 parts of high-density polyethylene, 10-15 parts of linear high-density polyethylene, 17-25 parts of medium-density polyethylene, 9-16 parts of linear medium-density polyethylene, 25-35 parts of low-density polyethylene, 13-18 parts of linear low-density polyethylene, 90-100 parts of polyvinyl chloride resin, 5-7 parts of carbon black, 40-50 parts of plasticizer, 3-8 parts of stabilizer, 20-26 parts of calcium carbonate or talcum powder, 2-4 parts of antioxidant and 1-3 parts of polyethylene wax. An outer sheath prepared from the material has excellent lubrication and wear-resisting properties, and therefore, the cable outer sheath is protected against damage due to friction in the mounting process.
