Problems solved by technology

In the actual application process, the control cable, especially the insulation layer in the control cable, has less research and development in terms of heat conduction and flame retardancy. The insulation layer may burn at a higher temperature, which will affect the normal operation of the control cable. Work safety and reliability are difficult to guarantee

Abstract

The invention discloses a heat conducting flame-retardant control cable which comprises a core, an insulating layer, a shielding layer and a sheath layer. The insulating layer wraps the core, the shielding layer wraps the insulating layer, and the sheath layer wraps the shielding layer; the insulating layer is made of low-smoke halogen-free polyolefin materials, the low-smoke halogen-free polyolefin materials comprise, by weight, polypropylene, methylvinyl silicone rubber, ethylene-vinyl acetate copolymers, tetra propyl ammonium phenylsulfonyl, isopropyl tri-(iso-stearoyl) titanate, caprolactam, magnesium oxide, 2, 5-dimethyl-2, 5-tert butyl peroxy-3-hexyne, alkylated diphenylamines, 2-mercapto benzimidazole zinc salt, dicyclohexyl phthalate, kaolin, cerium dioxide, polyacrylonitrile fibers, anti-aging agents and antioxidants. The heat conducting flame-retardant control cable has the advantages of good heat conductivity and excellent flame-retardant property.

Description

technical field [0001] The invention relates to the technical field of control cables, in particular to a heat-conducting and flame-retardant control cable. Background technique [0002] In various industrial and mining enterprises, transportation and other important economic sectors, such as power plants, substations, power lines and petrochemical enterprises, control cables are widely used. For the operation of safe power supply and production systems, the functions of control cables even exceed Power cables for main lines. In the actual application process, the control cable, especially the insulation layer in the control cable, has less research and development in terms of heat conduction and flame retardancy. The insulation layer may burn at a higher temperature, which will affect the normal operation of the control cable. Job security and reliability are difficult to guarantee. Contents of the invention [0003] The invention provides a thermally conductive and fla...
