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

Abstract

The invention discloses a cable sheath and a preparation method thereof, and relates to the technical field of cable sheaths. The cable sheath comprises main materials and auxiliary materials; the main materials comprise 50-60 parts of chloroprene rubber, 25-35 parts of natural rubber and 10-15 parts of epoxy resin; the auxiliary materials comprise 45-50 parts of modified nanocarbon, 25-30 parts of plant ash, 22-24 parts of white oil, 20-22 parts of paraffin, 15-20 parts of antioxidant TNP, 15-17 parts of smoke suppressor, 10-15 parts of flame retardant, 10-12 parts of lubricant, 8-10 parts of antioxidant, 5-7 parts of anti-ultraviolet agent, and 2-5 parts of colorant. The tensile strength and the elongation at break of the prepared cable sheath material are effectively improved.

Description

technical field [0001] The invention relates to the technical field of cable sheaths, in particular to a cable sheath and a preparation method thereof. Background technique [0002] Wire and cable are the carriers of power transmission and information transmission, and are widely used in industrial and civil electrical facilities. Wires and cables are used in different environments or occasions and have different requirements, which puts forward higher requirements for the cable sheath covering the outside of the cable. The main function of the cable sheath is to mechanically and electrically protect the transmission cable from various conditions that will cause it to lose its transmission function. The cable jacket must fulfill this protective function during installation, splicing and throughout the 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 should kee...
