Background technology
Electrical energy distribution is in inside and outside various pieces of building such as civilian, commercial, factories, and it is zero to be all impossible that any perfect fire prevention management makes the probability of electric energy breaking out of fire.Although fire department all emphasizes to strengthen fire prevention management every year, the also normal unexpectedly under cover danger of electric wire fire for various reasons.The maximum still circuit of harm case of electrical fire, as distribution lines such as cable, electric wires (comprising wiring duct).High level, Super High civil buildings, from fireproof angle out-degree, except thinking better of not the firing of building and finishing material, all kinds of cables that electrical equipment, distribution line adopt, electric wire, wiring duct more need to take the measure of fire-retardantization, difficult burning and not burning.Material majority high-rise, that the electrical equipment of high-rise building uses is organic compound, by the mode with insulating material, use, particularly plastics majority is inflammable, flammable material, during design and use, must give one's full attention to, should be in strict accordance with requirement design, type selecting and the mounting and installation of fire codes.In the last few years, because cable, electric wire, wiring duct catch fire to prolong to fire, led to fire disaster, all happened occasionally both at home and abroad; suffer heavy losses; caused people's deepest concern, and made people clearly realize that in building, electric wire, except fire prevention, also needs to do fire-resistant protection.At civil building, business office building, particularly large-scale computer room, mostly the laying of electric wire is that arranging and piling is in groove, once catch fire, all electric wires that ignited, consequence will be hardly imaginable, vertical especially electric well.Mostly the fire-resistant protection of electric wire is to improve the fire resistance of wiring duct.Domesticly occurred flame-proof PVC wiring duct, but electric wire itself has thermal losses, PVC material radiating effect is bad, and electric wire in PVC wiring duct, easily cause electric wire to heat up, so that electrical equipment damages for a long time.There is on the market now the anti-fiery blanket of a kind of PET, with PET (polyester fiber is moulded) glue, reeled off raw silk from cocoons and be woven into the form of blanket with mineral wool, be wrapped in the outside of wiring duct, can dispel the heat, anti-fire again, but fire resistance is bad.In engineering design, the temperature of electric wire can not surpass 140 ℃ and add environment temperature, because the fibre gap seam of braid is larger, easily sees through heat when the external world catches fire, and its fire resistance period is shortened, and can not reach the effect of effective anti-fire.
Summary of the invention
The invention provides a kind of anti-fiery blanket, there is good construction, ventilative perfect heat-dissipating, the fire-resistant excellent in performance that reaches 1.5 hours.Technical solution of the present invention:
Anti-fiery blanket, is characterized in that being comprised of aluminium film, PET blanket and expandable flame retardant glue-line, and described PET blanket is between aluminium film and expandable flame retardant glue-line.
Described PET blanket is that silk weaving becomes with PET by mineral wool.
Described expandable flame retardant glue is comprised of adhesive and the 30%-45% efficient expansion fire retardant of 55%-70%.
Described adhesive is melamine glue.
Described efficient expansion fire retardant is the fire retardant that contains N, P, C, and N, P, the C content (percentage by weight) in fire retardant is respectively N:5-10%, P:5-15%, C:3-10%.
The technology of the present invention effect
The anti-fiery blanket of the present invention consists of three layers, aluminium film, PET blanket and expandable flame retardant layer, and in construction, with anti-fiery blanket parcel wiring duct, aluminum film layer, has guaranteed the attractive in appearance of job site outwardly.Now on the market much for automobile sun-shading be exactly aluminium film, it has, and very high albedo is strong, the thermal efficiency is high, lightweight, is convenient to maintenance and changes.Aluminium film can make the infrared ray major part in sunshine reflect away, and makes to enter heat in automobile and the temperature rise in driver's cabin and significantly reduces, and not only can reduce the power of air-conditioning and the time of turning on the aircondition, and saves the energy.Utilize its reflecting properties and noninflammability, when extraneous breaking out of fire, reflecting heat, makes wiring duct be unlikely intensification too fast.By mineral wool, silk weaving becomes PET blanket with PET.Mineral wool is incombustible, after PET glue reels off raw silk from cocoons, is made into blanket with mineral wool, and interfibrous gap makes PET blanket have gas permeability.PET glue is high temperature resistant, can reach 180 ℃, meets the requirement that is no more than 140 ℃ of room temperatures in electric wire use procedure.The anti-chemical solvent of PET glue is good, produces less harmful substance during burning, less on the impact of the Nature.PET glue has high adhesion strength, can firmly expandable flame retardant layer be bonded together.PET glue softness is docile, during parcel wiring duct, can arbitrarily bend, and makes parcel more tight.Expandable flame retardant glue-line is comprised of adhesive and the 30%-45% efficient expansion fire retardant of 55%-70%.Efficient expansion fire retardant is the based carbon fiber fire retardant for containing N, P, C, N, P, the C content (percentage by weight) in fire retardant is respectively N:5-10%, P:5-15%, C:3-10%, this expansion type flame retardant is met fiery Self-expanding, formation is than the large tens times of porous carbon layers to decades of times of original volume, this is because N, P interact and produce the result of gas after being heated, after being heated, expand rapidly and carbonization, the existence that is C element makes burning form charring layer, reaches effective fireproof effect.Melamine claims again melamine, can be used as the adhesive of timber processing; The crosslinking agent of coating industry; In building material industry for the production of fire retardant and cement additire; Also can be used for the industries such as mold tool plastic, papermaking, leather, weaving and medicine, agricultural chemicals, be now widely used in furniture adhesive, is a kind of good environment-friendly products.Melamine in the present invention had both played adhesive, also had the effect of fire retardant simultaneously.Melamine is the just in time formation of efficient expansion fire retardant according to the invention of C, N structure, makes flame retardant effect better.
The preparation technology of the anti-fiery blanket of the present invention is simple, and equipment is cheap, and raw material are easy to get.PET blanket has been ripe product, on sale on the market.Aluminium film and PET blanket are combined with make-up machine note, the expansion glue mixing are coated on to the another side of PET blanket with coating machine, naturally dry.By three layers of twice production stage being bonded together, there is no dividing of priority, can be depending on producing.The anti-fiery blanket of the present invention, by the fire-resistant protection of three layers, the particularly effect of efficient expansion fire retardant, finally makes wiring duct can reach anti-fiery 1.5 hours through experiment showed,, has effectively prevented stretching of fire.The anti-fiery blanket of the present invention can also be for wrapping up airduct, and reservoir vessel is the storage tank of Organic Ingredients particularly, to the control of fire, plays a part crucial.
