Low-smoke, halogen-free and oil-resistant K3-class communication mobile cable for 1E type nuclear power plants

Abstract

The invention discloses a low-smoke, halogen-free and oil-resistant K3-class communication mobile cable for 1E type nuclear power plants. The low-smoke, halogen-free and oil-resistant K3-class communication mobile cable comprises a cable core and sheath layers. The sheath layers are made of, by weight, 20-40 parts of nitrile rubber, 5-15 parts of butadiene styrene rubber, 10-18 parts of ethylene propylene diene monomer rubber, 0.5-1.5 parts of zinc oxide, 1-3 parts of organosilane crosslinked polyethylene crosslinking agents, 1-2 parts of stearic acid, 1-2 parts of epoxy acetyl methyl linoleate, 0.5-1.5 parts of phenol formaldehyde resin, 0.1-0.6 part of dibenzothiazyl disulfide, 1-2 parts of anti-aging agents MBZ, 1-2 parts of anti-aging agents SP, 15-35 parts of diatomaceous earth, 5-15 parts of graphene nano-sheets, 10-20 parts of modified lignin, 10-30 parts of barite powder and 5-10 parts of activated calcium carbonate. The low-smoke, halogen-free and oil-resistant K3-class communication mobile cable has the advantages of good oil resistance, abrasion resistance, low-smoke and halogen-free properties and flame retardance, excellent mechanical properties and aging resistance and long service life.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a low-smoke, halogen-free, oil-resistant 1E-type nuclear power station K3 grade communication mobile cable. Background technique [0002] With the development of the national economy and the acceleration of informatization, the coverage of communication cables used as communication carriers is becoming more and more extensive. However, communication and mobile cable materials require a wide variety of raw materials, high production costs, and flame-retardant and fire-resistant properties. Poor, it is easy to cause serious safety accidents in the event of a fire, causing a large amount of economic and property losses, and producing a large amount of smoke, which not only endangers people's health but also pollutes the environment. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a low-smoke, h...
