Abstract

The invention discloses an anti-electromagnetic and waterproof power cable outer sheath. The anti-electromagnetic and waterproof power cable outer sheath is prepared from components in parts by weightas follows: 68-90 parts of modified polyurethane resin, 50-66 parts of ethylene propylene diene monomer rubber, 10-20 parts of a polypropylene emulsion, 20-30 parts of crosslinked polyethylene, 12-22parts of polyacrylonitrile fiber, 10-15 parts of maleic anhydride, 11-14 parts of silicon dioxide, 7-10 parts of silicone oil, 4-7 parts of a composite flame retardant, 3-7 parts of calcined kaolin,6-12 parts of iron oxide, 8-12 parts of a plasticizer, 2-6 parts of a reinforcing agent and 3-5 parts of an anti-ageing agent. The cable outer sheath has the characteristics of being good in flame retardance, high in tensile strength, high in anti-electromagnetic capacity, good in ageing resistance and good in water-proof property and is very applicable to various cable materials, and the stability and the safety of cables are improved.

Description

technical field [0001] The invention relates to the field of cables, in particular to an outer sheath of an anti-electromagnetic waterproof power cable. Background technique [0002] With the development of social economy, cables are widely used in aerospace, electronics, machinery and other fields. According to the different working environment of the cable, there are different requirements for the performance of the cable. Wires and cables have a wide range of uses, and their performance requirements vary greatly in different use occasions. The sheath materials of most cables must not only have high insulation resistance, withstand voltage strength or low dielectric loss, but also have good physical and mechanical properties, such as tensile resistance, bending resistance, vibration resistance, torsion resistance, etc. ; And due to the need to adapt to different use environments and occasions, there are requirements for tear resistance, high and low temperature resistanc...
