The invention has the beneficial effects as follows：Heat-resisting, high temperature resistant：Cable adapts to 150 ~ 250 DEG C of hot environment.Overload capacity
Relatively strong, no elastomeric state under high temperature, it is difficult to shrink, causes so as to avoid electric wire thermal contraction the insulation at product two ends to reveal conductor.High
Anti-flammability：Oxygen index (OI) height, during burning, flame spread scope is little, and the amount of smoke of generation is few.The public arenas such as intelligent Building, once send out
Light a fire calamity, not by dense smoke smoked fall, win the alienation time of preciousness.Excellent electric properties：With excellent electrical insulation capability,
High voltage withstanding, high-frequency loss is little, nonhygroscopic, the dielectric strength of the big cable of insulation resistance, insulation resistance are good, decays little beneficial to high frequency
Signal transmission.With excellent mechanical and physical performance：The stability of height, is hardly acted upon by temperature changes, and has excellent
Weather-resistant performance and mechanical strength；Its tensile strength is more than 5 times of polrvinyl chloride, and flexibility is good, and not
By various acid, alkali and organic solvent influence.Therefore be applied to amblent air temperature change greatly, be corrosive occasion.Chemical backbone bond energy
High：Sunlight can be stood or by ultraviolet long-term irradiation, the ultraviolet aging of resistance to day is good, with excellent resistance to combustion, wear-resisting, resistance to old
Change performance service life longer.Anti-oxidation conductor：It is welded to connect beneficial to soldered wires product, the melting of conventional products insulation
Temperature is low, easily melts in high temperature, intelligent building fire resistant electric wire cable product.Because of its high-temperature stability（150-250℃）Just
In communication equipment and the back panel wiring of electronic machine.Drastically increase intelligent building wiring safety, reliability and be suitable for
Property, the generation of dangerous accident can be effectively prevented, of many uses, market capacity is big.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Wherein：1 is high-temperaure coating, 2 is synthesis fluorine gold fireproof mica layer, 3 is PTFE inner insulating layer, 4 is GPA modification Buddhist nun
Imperial insulating barrier.
Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings.
Intelligent building fire resistant electric wire cable, the structure of described electric wire is covered with high temperature resistant painting for interior core outer surface
Layer 1, inner core is coated with synthesis fluorine gold fireproof mica layer 2, and synthesis fluorine gold fireproof mica layer 2 is coated with PTFE inner insulating layer 3,
The outermost layer of electric wire is GPA modification of nylon insulating barrier 4.
Described high-temperaure coating 1 is heat-resisting silicon nitrogen gel coating.
Described synthesis fluorophologopite layer 2 is bonded with silicon resin adhesive.
Described inner core is made up of silver jacketed wire, nickel plated copper wire or bare copper wire.
The PTFE inner insulating layer 3 of described electric wire and 4 production technology of GPA modification of nylon insulating barrier are for extruder once
Molding, is successively extruded using two head 1+1 modes, and 3 head of PTFE inner insulating layer is that adjustable offset head, GPA modification of nylon is exhausted
4 head of edge layer is for exempting from eccentric centering head.
Described technique raw material enter extruder before, respectively through 56 mesh and 80 mesh two-layer strainer filterings.
Described technique has vacuum equipment after 4 cross-head of GPA modification of nylon insulating barrier, extracts insulating surface gas
Body.
The technological process of production：Filter plate, filter screen are equipped with using separating screw rod（Filter screen is divided into+80 mesh of 56 mesh of two-layer）, flange
Chuck filters out granulometric impurity, incipient scorch granule to ensure plasticizing evenly, increases resistance and the counter-pressure of logistics, plastifies nylon
Evenly, it is ensured that big extrusion capacity.Insulation and sheath are successively once extruded by 1+1 mode using two heads, the nylon for extruding
Jacket thickness is very thin, only 0.1-0.3mm, therefore, if selecting the head of adjustable eccentric, then eccentric adjusting during sheathing
Highly difficult, it is that this my company devises the concentricity for exempting from that tuningout self-centering head improves insulation and sheath, insulation head is adjustable
Eccentric die, sheath head is to exempt from eccentric centering head.The advantage of this technique be operate simpler, it is easy to eccentric, with
Heart degree is good, smooth surface.Using the characteristic that the draw ratio scope of nylon is larger, can be extruded using the tubular molding tool of specification of the same race
The product of different size, is to reduce the air gap between insulation and sheath, installs evacuation additional after the cross-head of sheathing
Device, Main Function is to extract insulating surface gas, increases linear velocity, while increase the compactness between insulation and sheath, print
Word device should be placed between two tanks and carry out lettering, and lettering is imprinted on surface of insulating layer, and is in inside sheath, so being difficult to wipe
Fall.
