High-strength transparent cable sheath material

Abstract

The invention discloses a high-strength transparent cable sheath material which comprises the following raw materials in parts by mass: 50-80 parts of ethylene-vinyl acetate copolymer containing 18-20% of vinyl acetate, 20-40 parts of polyethylene terephthalate-1,4-cyclohexanedimethanol, 1-2 parts of plasticizer cyclohexane 1,2-di(2-propylheptyl) diformate, 20-50 parts of nitrile silicone rubber, 5-12 parts of nano silicon dioxide, 3-8 parts of calcium carbonate, 2-6 parts of acrylonitrile-butadiene-styrene terpolymer, 0.1-0.2 part of potassium perfluorobutanesulfonate, 5-10 parts of paraffin oil and 0.2-0.6 part of reinforcing agent DH-3. The sheath material disclosed by the invention has good transparency; in use, troubleshooting for the wire shielding damage is easy to realize, and the tracking of parallel wires and a connector and a circuit is simpler and easy to implement; and the sheath material disclosed by the invention has good transparency as well as relatively high mechanical strength and comprehensive performance and good stability.

Description

Technical field [0001] The invention relates to the field of cable processing materials, in particular to a high-strength transparent sheath material for external use of cables. Background technique [0002] Wires and cables are the carriers of power transmission and information transmission, and are widely used in industrial and civil power facilities. Wires and cables are used in different environments or occasions and have different requirements, which puts forward higher requirements for the cable sheath that covers the cable. The main function of the cable sheath is to mechanically and electrically protect the transmission cable from various conditions that would make it lose its transmission function. The cable sheath must complete this protection function during installation, connection and the entire service life of the cable. During the service life of the cable, the sheath must protect the cable core from moisture and other pollution. The degree of protection must kee...

AI Technical Summary

Problems solved by technology

During the service life of the cable, the sheath must protect the cable core from moisture and other pollution. The degree of protection should keep the circuit performance in the cable core normal. Once too much moisture or other pollutants enter the cable core, the transmission performance will be affected. will seriously deteriorate

This requires the cable sheath to have high mechanical strength and internal toughness to prevent cracking or damage in harsh environments, resulting in abnormal cable transmission or potential safety hazards

[0003] Most of the cable sheath materials in the prior art are opaque sheaths. Although they are widely used, they also have the disadvantages that it is not easy to troubleshoot the damage of the wire shield, parallel wires and connectors, and circuit tracking are relatively difficult; the existing Transparent sheaths are mostly simple soft plastics with low strength, which cannot meet the protection requirements for cables
