Abstract
The invention relates to a double-layer metal cladded flame-retardant electric cable which is manufactured by cladding an insulation layer and a conductive core wire, wherein the conductive core wire is manufactured by cladding double layers of different metal materials; the insulation layer is made of a smokeless and flame-retardance nano modified polyvinyl hydrocarbon polymer insulation material; a flame-retardance jacket is cladded outside the insulation layer; and the conductive core wire is made of copper clad aluminum, copper clad steel or aluminum clad steel. The double-layer metal cladded flame-retardant electric cable is safe and reliable, has less smoke generation amount in a combustion environment when accidents happen, better flame retardance and no harmless gases or corrosive gases and can be used for effectively reducing accidental loss and reducing material cost.
Description
Technical field
The present invention relates to a kind of electric wire, especially a kind of double-level-metal bag core flame-retardant electric wire and cable belongs to the electric product technical field.
Background technology
The electric wire of China enterprise production at present, formed by conductive core line and insulating material coating, conductive core line wherein adopts aluminium or copper material more, and outer field insulating material mainly is polyvinyl chloride and polythene material, weak point is: the electric conductivity of copper material is better than aluminium, but cost is higher; And the pliability of aluminium is better, conductivity a little less than, polyvinyl chloride, polyethylene wire and cable easy breaking out of fire when the electrical system accidental short circuit in the insulating material, produce pernicious gas, especially the chlorinty of polychloroethylene insulation material can discharge the toxic smog of high concentration up to more than 56% during burning, obstructs the view, influence escape and fire extinguishing, even direct causing death.
Along with scientific and technological progress and development; people also progressively improve the consciousness of environmental protection; biological environment, environment-friendly products, " green " food, " green " engineering or the like become one of focus of people's concern, and electric product is not only had the quality safety requirement, also require its environmental protection, economy simultaneously.
Summary of the invention
The objective of the invention is at the problems referred to above, a kind of double-level-metal bag core flame-retardant electric wire and cable is provided, improve its fail safe, reduce accidental loss, can reduce cost simultaneously.
Double-level-metal bag core flame-retardant electric wire and cable of the present invention, coat and form by insulating barrier, conductive core line, described conductive core line is that double-deck different metal materials coats composition, and insulating barrier is smokeless fire-retardant nano modification polyolefin insulating material of polymer, and described insulating barrier is coated with fire retardant jacket.
Described conductive core line can be copper cover aluminum or copper covered steel or aluminium Baogang and forms.
Insulating barrier and fire retardant jacket are to be mixed and made into by nano modification polyolefin polymer, nano-meter flame retardants, nanometer antismoke agent and compound.The percentage by weight of each component is: nano modification polyolefin polymer 30%-95%, nano-meter flame retardants 0.1%-50%, nanometer antismoke agent 0.01%-50%, compound 1%-50.
Double-level-metal bag core flame-retardant electric wire and cable of the present invention is safe and reliable, and the amount of being fuming that meets accident when being in burning situation is few, has anti-flammability preferably, and no pernicious gas and corrosive gas can effectively reduce accidental loss, can reduce material cost simultaneously.
