Abstract

The invention discloses a flame retardation control cable with excellent mechanical performances. The flame retardation control cable comprises a cable core, an insulation layer, a shielding layer and a sheath layer, the insulation layer is coated outside the cable core, the shielding layer is coated outside the insulation layer, and the sheath layer is coated outside the shielding layer, wherein the insulation layer is made of modified polypropylene. Raw materials of the modified polypropylene comprise polyethylene, polypropylene, chloroprene rubber, vinyltriethoxysilane, tert-amylperoxy 2-ethylhexyl carbonate, diethylenetriamine, dibutyltin dilaurate, styrenated N-phenylbenzenamine, 3,5-di-t-butyl-4-hydroxycinnamic acid, di-n-octyl phthalate, carboxymethylcellulose sodium, paraffin, magnesium stearate, diatomite and talcum powder. The cable has the advantages of good thermal stability, excellent flame retardation performance and excellent mechanical performances.

Description

technical field [0001] The invention relates to the technical field of control cables, in particular to a flame-retardant control cable with excellent mechanical properties. Background technique [0002] The control cable is mainly used in the automation control system and the automation connection system, and the transmission control completes the corresponding instructions. The insulation layer of the control cable mainly includes polyvinyl chloride and cross-linked polyolefin, and most of the sheath is polyvinyl chloride. This kind of cable has no flame retardant properties and poor thermal stability due to non-metallic materials. In the fire environment, the insulation and sheath materials are quickly destroyed, causing the control system to fail, and the combustion releases toxic gases such as halogens. Equipment and personal safety pose a threat, and the smoke screen released seriously affects people's rescue and escape, so it cannot be used in office buildings, resid...
