Description
Technical field
The present invention relates to technical field of cable, specially a kind of isolated form flexible fire-proof cable and its manufacturing method.
Background technology
Traditional fireproof cable is magnesium oxide insulated copper sheath rigid cable, however the cable is in long-term use,
Disadvantage gradually shows especially out, first the harder unsuitable mobile occasion of its structure, and secondly cable is easy the moisture absorption due to magnesium oxide insulated,
Cable is longitudinally moisture-proof to be required and especially seems important from protective metal shell damage, and end uses fluid sealant, can seriously affect use
Service life；Furthermore manufacturing process also limits the factory length of cable, and connector is caused to increase, and the water-proofing treatment of connector is also highly difficult,
Often because joint intakes, cause insulation resistance unqualified.
Related architectural design department proposes various fire protection requirements to building wire cable, with adapt to and meet safety,
The demand of environmental protection, is mainly used in important building place, such as the place that the crowd is dense：Shopping square, theater, hotel；One
A little important buildings：The important engineering project etc. such as high-end residential building, skyscraper, banking house, office building.
For the defect present in fireproof cable currently used in the market, knot of each producer from change fireproof cable
Structure, material and processing technology mode etc. develop all kinds of fireproof cables.The rated voltage 0.6/1kV that is developed such as my company and
Following inorganic mineral isolated form flexible fire-proof cable, the fireproof cable have had both conventional rigid fireproof cable and modified flexibility simultaneously
The advantages of fire-resisting cable, overcomes the deficiency of the two.
Invention content
Technical problem to be solved by the present invention lies in provide one kind having simple in structure, easy to operate, the fire resistance period of production
Isolated form flexible fire-proof cable long, that performance is stablized.
A kind of isolated form flexible fire-proof cable, including power wire core and ground connection core, the power wire core and ground connection core
Include power conductor and earth conductor, the outside of the power conductor and earth conductor be coated with successively flame retardant coating, insulating layer,
Aluminium clad and dichroic layer, the power wire core and ground connection core twisted synthesizing cable constitute cable core, are coated successively outside the cable core
There are inorganic mineral oxygen barrier layer, fire resisting isolation strip and oversheath, inorganic mineral is set between the cable core and inorganic mineral oxygen barrier layer
Filled layer.
Soft calcined clay has superior dispersibility and plasticity in the present invention, and combination can be served as in formula system
Agent.Magnesium hydroxide is that filled-type fire retardant is used as in formula system, acts through and is released when being thermally decomposed in conjunction with water, is absorbed
A large amount of latent heat has and polymer is inhibited to decompose and right to reduce the surface temperature of synthetic material that it is filled in flame
Generated fuel gas carries out cooling effect, and the magnesia for decomposing generation is good refractory material again, can also help to carry
The fire resistance of high material achievees the effect that fire-proof and thermal-insulation, while the vapor that it is released also can be used as a kind of smoke suppressant.Hydrogen-oxygen
Change aluminium in formula system, bundle and use with magnesium hydroxide, can not only fire retardation, and smoke can be prevented, do not generate drop
Lower object does not generate toxic gas, has more environment protecting, prevents cable that afterflame occurs, and also avoids the two of toxic gas generation
Secondary harm.Sodium metasilicate glue plays adhesive effect.Superfine talcum powder can improve the adhesive force of entire fire clay at high temperature, also have
There are certain viscous force, protection and stability.Calcium montmorillonite has suction-operated, optimization adhesive force, resistance to organic or inorganic ion
It is aqueous etc., therefore cohesive force is fine.High temperature resistant that silica flour has, coefficient of thermal expansion be small, high-insulation, corrosion-resistant, piezoelectric effect,
Resonance effect and its unique optical characteristics.Enhancing retarder, there is stronger active function, the purpose that retarder is added to be
In order to extend the hydration and hardening time, make to keep plasticity in for a long time.
A kind of manufacturing method of isolated form flexible fire-proof cable, includes the following steps,
(1), it is twisted core, multiply copper free wire is twisted into power wire core and ground connection battery core respectively；
(2), twisted cable core will be extruded to be twisted into after Ceramic silicon rubber insulating layer outside power wire core and ground connection core and be cut
Area≤16mm2Small bore cable, will be extruded outside power wire core and ground connection core be twisted into after dichroic layer sectional area >=
25mm2Electric cable with large cross-section；

5 1.5 parts.
The aluminium clad be by after the filtered cleaning of fine aluminium bar, high temperature is extruded into tubulose, be coated on power wire core and
On ground connection core insulating layer.
The small bore cable, i.e. sectional area≤16mm2Cable using system alclad clad structure, the big section electricity
Cable, i.e. sectional area >=25mm2Cable using subitem extrude aluminium clad structure.
The dichroic layer is to be extruded in power wire core and ground connection core aluminium clad to form by hydrophobic polyethylene material,
By red, yellow, green, blue, black multicolored color separation.
The inorganic mineral filled layer and inorganic mineral oxygen barrier layer are extruded by heat-insulating, fire-preventing inorganic mineral oxygen barrier layer pug
It forming, ovality≤25% after extruding, the fire resisting isolation strip is formed by wrapped multilayer low-smoke bittern-free highly fire-proof glass fibre belt,
Cap rate is 15~20%.
The oversheath is extruded by crocus low-smoke non-halogen flame-retardant environment-friendly polyolefin material.
Insulating materials of the present invention using high insulation, high fire resisting, free of contamination Ceramic silicon rubber, insulate 650 DEG C~
Under 1000 DEG C of high temperature, be converted into hard inorganic SiO2 ceramic shells, play at high temperature good fire-retardant, fire resisting, fire prevention, every
The effect of fire, water proof and antidetonation, plays a very good protection to entire circuit, ensures the long-time of circuit in case of fire
It is unimpeded, it is a kind of fireproof cable truly；Product has passed through 1000 DEG C, and the fire resistance test of 5h, fire resistance rating not only surpasses
