Abstract

The invention relates to a ceramic fireproof fire-resistant silicon rubber wire and cable. The wire and cable comprise a plurality of conductors, each conductor is wrapped by a ceramic silicon rubber insulating layer in an extruding mode to form a wire core, multiple wire cores are wrapped by a wrapping tape layer to form a cable core, padding is arranged in the cable core, and a ceramic silicon rubber outer sheath is arranged outside the cable core. The ceramic fireproof fire-resistant silicon rubber wire and cable have characteristics batter than those of a common rubber cable and a flame retardant rubber cable and form a hard shell after being ablated by high-temperature flames to protect a burned article from being damaged, and the hard shell formed after ablation protects the wire and cable, so that unblocked electric power and communication are ensured, and precious time are won for personnel evacuation and rescue under the fire disaster condition.

Description

Ceramic fireproof=fire-proof silicone rubber wire cable
Technical field
The present invention relates to a kind of electric wire, relate in particular to a kind of ceramic fireproof=fire-proof silicone rubber wire cable.
Background technology
In the last few years, after the large-scale place of public amusement of domestic several families, chemical industry, colliery, mall fire cause painful people's life and property heavy losses, people had had more deep understanding to fire-fighting, fire safety.Sharp increase along with urban population, skyscraper, hotel, large supermarket, hospital, station, airport constantly increase, the construction of subway, tunnel traffic, and the increase of large-scale Public Physical Education, public place of entertainment, public transit facility, the importance of fire-fighting, fire safety shows especially out.How, in the situation that fire ensures the unimpeded of electric power and communication within a certain period of time, win to greatest extent valuable rescue time, reduce personnel's injures and deaths and the loss of lives and properties, this is that people are always in the problem of constantly exploring.
What adopt both at home and abroad at present, is the fire-resisting cable that magnesium oxide mineral fire-proof insulation cable and mica tape are wound around mostly.Magnesium oxide mineral fire-proof insulation cable needs special manufacturing and processing equipment, and the equipment of in addition producing magnesium oxide mineral fire-proof insulation cable not only needs import, and very expensive, and fund input is too large; In addition, the outer jacket of magnesium oxide mineral fire-proof insulation cable is full copper, higher on cost, is subject to restriction to a certain extent aspect practical application; Add the specific (special) requirements of copper sheath magnesium oxide mineral fire-proof insulation cable in the processes such as the laying installation of production and processing, transportation, circuit and use, it is convenient as the production and processing of magnesium oxide mineral fire-proof insulation cable can not the image height molecular material, the laying installation difficulty is large, cost of raw material cost is high, be difficult to universal use the on a large scale, be difficult to especially promote on civil buildings etc.And the fire-resisting cable that mica tape is wound around, need in process of production multi-lay winding, restriction due to process conditions, often easily cause overlapping the slot place defect to occur, mica tape embrittlement after burning, easily come off, also cause fire-resistant weak effect, thereby be difficult to ensure safe and smooth under fire condition of communication, electric power.
Summary of the invention
The present invention provides the ceramic of a kind of good flame retardation effect, long service life, low smoke, zero halogen fireproof=fire-proof silicone rubber wire cable in order to overcome the above problems.
Technical scheme of the present invention is: comprise many conductors, described conductor extrudes the ceramic silicone rubber insulation layer outward and forms core, and a plurality of cores extrude belting layer and form cable core, are provided with filling in cable core, and described cable core is provided with ceramic silicon rubber oversheath outward.
The described glass fibre inserts that is filled to.
Described belting layer is the glass fibre band.
The present invention has the characteristic that is better than General Purpose Rubber cable and flame retardant rubber cable; ceramic fireproof=fire-proof silicone rubber for cable has possessed the performance of ordinary silicon rubber cable at normal temperatures; form hard housing after the ablation of thermal-flame, the object that protection is burnt is not damaged.With ceramic fireproof=fire-proof silicone rubber wire cable, the hard housing of ablated rear formation is being protected electric wire, thereby has guaranteed the unimpeded of electric power, communication, for the valuable time has been won in evacuation and the rescue of personnel under fire condition.
Silicon rubber of the present invention is to add white carbon, silicone oil in methyl vinyl silicone rubber, and other auxiliary agent, after mixing, adds vulcanizing agent (two-2,5) in mill, then passes through mold pressing, extrudes, and makes cable.
This cable can be single cored structure, also multicore structure.The structure of single-core cable is copper conductor and fire-resistant silicon rubber insulation.The structure of multicore cable is copper conductor, fire-resistant silicon rubber insulation, glass fibre filling, glass fibre band, fire-resistant silicon rubber sheath.
Advantage of the present invention is:
1) in 650~1000 ℃ or above flame, through 90~180 minutes or above time ablation, silicon rubber is sintered into hard ceramic housing in a short period of time, hard ceramic housing, guaranteed that circuit is in ablated process, do not open circuit, not short circuit, do not prolong combustion, extraordinary anti-flammability is arranged, thereby guaranteed that circuit does not cut off the power supply in fire, for escaping and rescuing fire, provide guarantee;
2) have the characteristics of fire-retardant, Halogen, low cigarette, meet the ROHS of European Union instruction, non-corrosiveness and toxicant and γ-ray emission during burning, can not cause secondary harm to disaster-stricken people;
3) the hard housing be sintered into, the vibrations that can bear spray and the some strength of certain water, can guarantee that circuit does not rupture, not short circuit, for fire protection provides necessary prerequisite guarantee;
4) due to extraordinary anti-flammability being arranged, the protectiveness of hard housing, cause in conductor fusing (1083 ℃) process not short circuit, not on fire at carrying overload, excess load, short circuit current, the copper liquid that conductor fusing forms does not flow out outside line, has stopped the disaster hidden-trouble that electric wire overload, short circuit cause;
5) possessed at normal temperatures high temperature resistant, anti-aging, the good characteristics such as electrical property of ordinary silicon rubber wire cable;
6) production of the present invention, processing are the same with the processing technology of ordinary silicon rubber wire cable, do not need to change technique and increase equipment, without being wound around mica tape, asbestos etc., an extrusion molding, both can do fireprotection layer, insulating barrier, also can partly make sheath, simplify the processing technology of fire-resistant wire and cable, thus decrease cost;
7) under fire condition, can guarantee the unimpeded of communication, power circuit, for the quality time is won in the rescue of life, property, for reducing fire damage, make significant contribution.
Good fire-fighting, fire performance that the present invention possesses, make it can be widely used in public fire protection, the very high place of fire safety requirement.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1 is conductor, the 2nd, and insulating barrier, the 3rd, fill, the 4th, belting layer, the 5th, oversheath.
