Technical field:
The present invention relates to a kind of environment friendly nano composite high polymer control cable.
Background technology:
Conventional electric wire is quite serious pollutant sources, and it can produce public hazards such as a large amount of dioxin, lead, halogen when manufacturing, use and waste treatment.In recent years; Europe, the U.S. and Japan attach great importance to the relevant public hazards of electric wire; Its government not only carries out strict control to the emission in the cables manufacturing process; And the processing of scrapping cable implemented comprehensive monitoring, and force traditional cable manufacturer to use the material of compliance with environmental protection requirements to replace traditional material, make environment friendly nano composite high polymer cable or so-called " clean type cable ".
At present; The cable of selling on the market has low smoke and zero halogen control cable, anti-ant or protection against rodents control cable, waterproof control cable, fire-retardant control cable, fireproof control cable, flame-retardant control cable etc.; The main security performance of these cables is dull, and can not adapt to has two and above security performance needs; The public arena that personnel such as light rail subway, nuclear industry, airport, station, offshore platform, hospital, office building relatively concentrate and the important area of industrial and mining enterprises require cable to have high environmental-protecting performance and high-intensity performance; These zones also are the places that termite or mouse wreak havoc simultaneously; Require cable to have anti-ant mouse performance; The place that personnel concentrate also requires when breaking out of fire cable can guarantee operation a period of time; The personnel of assurance have enough time escapes; More or less have water or steam to exist in the cable passage in above-mentioned place, require cable that good block-water performance and high-intensity performance are arranged, the cable with single security performance that is applied to above-mentioned place thus can not guarantee safe operation.
Summary of the invention:
For overcoming the defective of prior art; The object of the present invention is to provide a kind of environment friendly nano composite high polymer control cable, it produces less smog and does not produce harmful halogen acid gas, outstanding anti-ant mouse performance, good flame-retardant performance, the axial block-water performance in footpath and high-intensity performance when possessing high environmental-protecting performance, burning.
Technical solution problem of the present invention adopts following technical scheme:
The environment friendly nano composite high polymer control cable; Be twisted into cable conductor by many insulated core; Be provided with packed layer in said cable core gap; Said insulated wire cores from-inner-to-outer is made up of conductor, interior mica tape flame retardant coating and insulating barrier, and said insulating barrier is a polyethylene montmorillonite-based nano composite insulation layer, outside said cable core and packed layer, is provided with the polyester belt that blocks water, belting layer, outer mica tape flame retardant coating, oxygen barrier watertight composition, galvanized steel strip armour and restrictive coating successively.
Design feature of the present invention also is:
Mica tape flame retardant coating and outer mica tape flame retardant coating all adopt synthetic fluorophlogopite belt in said.
Said packed layer adopts the polyester yarn that blocks water.
Said belting layer adopts the alkali-free glass fibre band.
Said restrictive coating is the polyolefin oversheath.
Compared with present technology, beneficial effect of the present invention is embodied in:
Conductor adopts the 5th type tin-coated copper core conductor, can prevent the corrosion of moisture content and other harmful substance; Insulating material adopts polyethylene montmorillonite-based nano polyblend insulating barrier, and this material not only has the superior electrical property of polyethylene, and compares with common polythene; Its mechanical performance is improved greatly; Especially tensile strength is several times of common polythene, and the environmental stress resistance performance of this material also improves a lot in addition, and common polythene material environmental stress resistance performance is poor; The insulation cracking phenomena in use appears easily; But the environmental stress resistance performance of this new material obtains very big improvement, has avoided cable the phenomenon that insulate and ftracture, the useful life of having improved cable greatly in use to occur; Packed layer and Halogen belting layer adopt block water polyester yarn and alkali-free glass fibre band respectively, and its capacity surpasses 50ml/g, prevent that effectively moisture from immersing; Flame retardant coating adopts synthetic fluorophologopite carrying material, and it does not contain the crystallization water, has good resistance to elevated temperatures and flame resistance ability, and fusing point is 1375 ℃, can make cable reach the fire-resistant level of A level (950～1000 ℃); The oxygen barrier watertight composition adopts the low smoke halogen-free flame-retardant polyolefin of high oxygen index, and this material oxygen barrier index reaches 40%, and has humidity resistance; Armour adopts double-deck zinc-plated steel-tape armouring; This material has high corrosion resistance; Compare its corrosion resistance with common plating lacquer steel band and improve greatly, the mechanical resistance pulling force and the compressive resistance of steel band are also higher, can bear the mechanical force that comes from the outside in the cable use; This material has also been avoided the magnetic hysteresis loss that cable in use produces in addition, has improved the bearing capacity of cable; Restrictive coating adopts the anti-ant mouse polyolefine material of resistant environmental low-smoke halogen-free flame; This material adopts the termite-resistant rodent-resistant repellant that from multiple natural plants, extracts; After repeatedly compound, add in the cable sheath material, make cable jacket contain a kind of specific peculiar smell, detest and reject contact because of its sense of smell is upset behind the mouse ant class animal contact cable; Also can send impalpable information and produce population effect simultaneously, thereby reach the purpose that the protection cable is not destroyed by the mouse ant to colony.Smoke density was very low when product of the present invention had burning; Non-corrosiveness gas is overflowed; Do not produce harmful halogen acid gas yet; Termite-proof and mouse bites; Possess simultaneously the footpath axially waterproof, high flame retardant and fire-resistant, insulation mechanical strength height and multiple performance such as the environmental stress resistance performance is strong and the little bearing capacity of cable loss is strong have in public arena that personnel relatively concentrate and the environmental-protecting performance of the cable that important area uses of industrial and mining enterprises in the special cable of one, can be widely used in nuclear power station, subway station, telephone exchange and computer controlling center, skyscraper building, hotel, TV and Radio Service, hospital, office building, important military installations, oil platform etc.; And the concentrated place of personnel, also be widely used in China temperate zone and subtropical zone many mouse ant area.In a word, this invention product be a kind of with environmental protection, block water, ant-proof mouse-proof, fire-retardant, fire-resistant, new product that security performance is integrated in one such as mechanical strength is high, bearing capacity is strong, vast market prospect is arranged.
