Description
Technical field
The present invention relates to material production technical field, and in particular to a kind of insulated flame-resistant cable of silicon-carbon doping and its preparation
Method.
Background technology
The flame retardant coating and insulating barrier of fire-resisting cable common at present use magnesia, magnesium hydroxide or mica band winding mostly
Deng fireproof cable, refractory temperature is higher（1000 DEG C or so）, but such cable manufacturing process is complicated, to equipment requirement compared with
Height, fund input is larger, and the function such as waterproof, anticollision is poor, has been difficult the demand for meeting market.Probe into higher resistance to
Fiery temperature, simple production process and the cable with relative specific function, become the focus studied in the last few years.
The content of the invention
It is an object of the invention to provide insulated flame-resistant cable of a kind of silicon-carbon doping and preparation method thereof, electricity can be ensured
Power, communication line in the case of fire safe and smooth.
Technical solution of the present invention is：
Four cable cores, metal are sequentially provided with from inside to outside inside a kind of insulated flame-resistant cable of silicon-carbon doping, the cable
Sheath, insulating barrier, the first band, flame retardant coating, the second band, and oversheath, internal four core centers are provided with center-filled
Layer.
Preferably, there is silicon rubber filling layer between the internal core, center-filled layer and protective metal shell.Silicon rubber is in metal
Inner core and the wrapped interlayer of metal form another packed layer, and when running into fire, this packed layer can form ceramic structure, so as to hinder
The heat transfer only produced during flame combustion is to metal inside, and the effective of extension cable utilizes the time, while can also be in fire extinguishing
When, contact of the moisture to cable inner core is prevented, buffer action is played.
Preferably, the center-filled layer material is glass fibre；The material of the protective metal shell is metallic aluminium.Improve light
The flexibility of cable.Aluminum metal, due to can continuously extrude, is the preferable protective metal shell material of flexible mineral insulation cable.
Preferably, first band and the second band, wrapped outside insulating barrier and flame retardant coating respectively, be not required to it is stranded,
Formed with glass fibre is wrapped.Need not be stranded, water resistance is good.Described the first band and the second band, is glass
Fiber band is wrapped to be formed, flexible preferable.Preferably, described oversheath is Low-smoke halogen-free environment-friendlyflame-retardant flame-retardant oversheath, and its material is
Ceramic high polymer or low-smoke halogen-free polyolefin or PVC or PE or EVA or EVM or EPM or EPDM or other.
Preferably, the insulating barrier be and flame retardant coating material be magnesia, carbon-silicon compound, silica, mica powder,
Kaolinic mixture.So that insulating barrier and flame retardant coating have higher melt, burning is not easy under flame condition.
It is further preferred that the magnesia, carbon-silicon compound, silica, mica powder, kaolinic weight ratio be 1 ~
