Description
Technical field:
The present invention relates to the anti-ant mouse water proof fire retardant fireproof control cable of a kind of low smoke and zero halogen.
Background technology:
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; These zones also are the places that termite or mouse wreak havoc simultaneously; Require cable that the ant-proof mouse-proof performance is arranged; The place that personnel concentrate also requires when breaking out of fire cable can guarantee operation a period of time, and 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 is arranged, the cable with single security performance that is applied to above-mentioned place thus can not guarantee safe operation.The low smoke and zero halogen fire protection flame retarding is prevented ant mouse water proof fire retardant fireproof control cable; Its material is not halogen-containing; Can delay to catch fire, reduce flame propagation velocity during burning; And after leaving external flame, himself combustion flame is can be rapidly less and have an electric wire that stops or delay propagation of flame from the flue dust of horizontal blanking and generation.Non-fire-retardant control cable can discharge a large amount of smog and corrosive gas when burning; Can damage valuable electronic instrument and equipment; Have a strong impact on withdrawing of fire-fighting and rescue and Field Force, the casualties that causes and to the harm of the secondary of electric equipment much larger than fire itself.Use non-harmful Halogen, low cigarette, low toxicity, fire-retardant control cable.The major contribution that the harm that produces to environment when using just because of this kind control cable is very little, environment for human survival and people's life, property safety are ensured; Therefore, its application will enlarge and be widely used day by day, and a few years from now on will bring good economic benefit and social benefit for enterprise.
Summary of the invention:
For overcoming the defective of prior art; The object of the present invention is to provide a kind of low smoke and zero halogen to prevent ant mouse water proof fire retardant fireproof control cable, produce less smog when it possesses high environmental-protecting performance, high flame resistance, burning and do not produce harmful halogen acid gas, outstanding ant-proof mouse-proof performance, good fire resistance can and the good axial block-water performance in footpath.
Technical solution problem of the present invention adopts following technical scheme:
Low smoke and zero halogen is prevented ant mouse water proof fire retardant fireproof control cable; Cable conductor is by the stranded stranding of split conductor core; Be provided with packed layer in the cable core gap; Said insulated wire cores from-inner-to-outer is made up of conductor, interior mica tape flame retardant coating, insulating barrier, in said, is provided with interior belting layer between mica tape flame retardant coating and the said insulating barrier, and said cable core and packed layer are provided with the polyester belt that blocks water, watertight insulation, outer mica tape flame retardant coating, outer belting layer, oxygen barrier watertight composition and restrictive coating outward successively.
Design feature of the present invention also is:
Mica tape flame retardant coating, outer mica tape flame retardant coating adopt synthetic fluorophlogopite belt in said.
Said insulating barrier is a polyolefin insulation layer.
Belting layer and outer belting layer all adopt polyester belt in said, and said packed layer adopts the polyester yarn that blocks water.
Said watertight insulation adopts aluminium-plastic tape.
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, and packed layer and inside and outside belting layer adopt the block water polyester yarn and the polyester belt that blocks water; Its capacity surpasses 50ml/g, and watertight insulation adopts the melting welding of aluminum plastic composite belt longitudinal bag, and sealing property is good; Prevent that effectively moisture from immersing, the oxygen barrier watertight composition adopts the low-smoke halogen-free polyolefin of high oxygen index, and this material oxygen barrier index reaches 40%; And have humidity resistance, and inside and outside mica tape flame retardant coating adopts synthetic fluorophologopite carrying material, and it does not contain the crystallization water; Have good resistance to elevated temperatures and flame resistance ability, fusing point is 1375 ℃, can make cable reach the fire-resistant level of A level (950～1000 ℃); Restrictive coating adopts the anti-ant mouse polyolefine material of resistant environmental low-smoke halogen-free flame, and this material adopts the termite-resistant rodent-resistant repellant that from multiple natural plants, extracts, and after repeatedly compound, adds 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 to colony; Thereby reach the purpose that the protection cable is not destroyed by the mouse ant; Smoke density was very low when product of the present invention had burning, and non-corrosiveness gas is overflowed, and does not also produce harmful hydracid material; Termite-proof and mouse bites; Possess simultaneously the footpath axially waterproof, high flame retardant and multiple performance such as fire-resistant 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 is a kind of with environmental protection, blocks water, and the new product that ant-proof mouse-proof, high flame retardant and security performance such as fire-resistant are integrated in one has vast market prospect.
