Description

Environmental-friendly halogen-free low-smoke nylon electric wire
Technical field
The present invention relates to electric wire, specifically is about the low smoke and zero halogen plastic insulation of use environment-friendly type and the novel environment friendly electric wire of nylon sheath wire.
Background technology
Present stage, the most BLV that are used for engineering construction, market sale all be with common igelite to the coating of insulating of electrician's circular copper wire, its production technology is simple, performance is qualified, cheap, so be widely adopted.But it is exactly that anti-flammability is bad that this class electric wire has a fatal defective, promptly in case run into naked light, just burn easily, igelite can produce the black solid derivative, give out black smoke, and discharge and to have poisonous halogen acid gas, derivative and gas that these burnings cause are only breaking out of fire, the real arch-criminal of the accident that causes casualties.
Summary of the invention
At above defective, the object of the present invention is to provide a kind of nylon flexible wire with the environmental-friendly halogen-free low-smoke insulation, be with the temperature control respectively of integral type head, when the wire conductor core goes out head, with environmental-friendly halogen-free low-smoke plastics and nylon, extrude simultaneously and finish.
Technical scheme of the present invention realizes in the following manner: environmental-friendly halogen-free low-smoke nylon electric wire may further comprise the steps: 1) the integral type head is heated; 2) environmental-friendly halogen-free low-smoke plastics preheating; 3) unwrapping wire; 4) environmental protection low smoke and zero halogen plastics and nylon are extruded coating; 5) lettering, cooling; 6) dry take-up; It is characterized in that:
1), the environmental-friendly halogen-free low-smoke plastics have good flame-retardant effect, can effectively prevent the electric wire spontaneous combustion, or prevent electric wire continuity burning when running into naked light, stop propagation of flame;
2), electric wire no black smoke in naked light emerges, the harmful substance and the toxic gas of generation are few;
3), unwrapping wire:
4), the electrical property of this electric wire routine and the regulation that physical property satisfies national electric wire standard, as insulation resistance, conductor resistance, tensile strength, elongation at break etc.;
5), lettering, cooling: the electric wire after the coating enters the precooling of first segment tank, carries out dimensional measurement through the automatic caliper of infrared ray, enters the cooling of second water-saving groove behind the printer,loigh-speed lettering;
6), dry take-up.
Described step 3) unwrapping wire is that smoke density is not more than 250 at the nonflame state, has the flame state to be not more than 100; Oxygen index is not less than 30%; Halogen acid gas discharges content and is not more than 5mg/g; PH value is not less than 4.3.
The dry take-up of described step 6) is that the copper conductor core of electric wire is drawn from the tension stringing frame, enters in the integral type head through the straightener aligning, simultaneously environmental-friendly halogen-free low-smoke plastics and nylon material is added the feeding mouth in environmental protection material district and nylon material district respectively.
The present invention can satisfy the electrical property and the physical property of national electric wire standard code, can make electric wire have environmental protection quality and anti-flammability again, promotes the product safety coefficient, reduces the degree of property and loss of life or personal injury.Effectively stop the electric wire spontaneous combustion, or prevent electric wire continuity burning when running into naked light, stop propagation of flame.Electric wire no black smoke in naked light is emerged, and the harmful substance and the toxic gas of generation are few.And manufacturing process is uncomplicated, and insulating barrier and restrictive coating adhesion are strong, in conjunction with the tightness degree height, nylon layer seals no air fully, the surface is moist, rounding is attractive in appearance, when having environmental protection flame retardant, also have well waterproof and dampproof, oil resistant is wear-resisting, characteristic such as corrosion-resistant.
Embodiment
Environmental-friendly halogen-free low-smoke nylon electric wire, its production method is:
1, the integral type head is heated, and is made as two heating regions, and nylon material district and environmental protection material district: nylon material district temperature range is 230-260 ℃; Environmental protection material district temperature range is 180-220 ℃.When heating to the environmental protection material The pre-heat treatment of heating, 80-100 ℃ of temperature ranges, the time is no more than 3 hours.
2, unwrapping wire: the copper conductor core of electric wire is drawn from the tension stringing frame, enter in the integral type head, simultaneously environmental-friendly halogen-free low-smoke plastics and nylon material are added the feeding mouth in environmental protection material district and nylon material district respectively through straightener aligning.The admission velocity of copper conductor core, environmental protection low smoke and zero halogen plastics and nylon material is as the criterion with the external diameter of electric wire, for example the discharging speed of environmentally-friendly plastic and nylon is fast, the speed of unit traction will be accelerated, and suitably adjust, so that the external diameter of electric wire meets the requirements prescribed.
3, environmental protection low smoke and zero halogen plastics and nylon are extruded in same head simultaneously, are coated on the copper conductor core of electric wire.Electric wire environmentally-friendly plastic after the coating is at internal layer, and nylon is at skin.Speed is as the criterion with the external diameter of electric wire, can obtain satisfied electric wire external diameter by regulating discharging speed or hauling speed.The characteristic of environmental protection low smoke and zero halogen plastics has determined it to extrude and coating speed can not be too fast, generally is no more than 80 meters/minute.
4, lettering, cooling; Electric wire after the coating enters the precooling of first segment tank, and water temperature is: 20-60 ℃; Carry out dimensional measurement through the automatic caliper of infrared ray, can be accurate to 0.001mm, be higher than the 0.1mm of the general requirement of product; Again through the printer,loigh-speed lettering, print speed 1-100 rice/minute between; Enter the cooling of second water-saving groove at last, water temperature normal temperature.
5, dry take-up: dry up through the water outlet of second water-saving groove cooling back and to enter the take-up storage rack, through the power frequency spark tester voltage test.Test voltage is adjusted (thickness 0.25-0.5mm, voltage 4KV according to the thickness of plastic layer is different; Thickness 0.5-1.0mm, voltage 6KV; Thickness 1.0-1.5mm, voltage 10KV).Select for use suitable rolling core to be carried out to coil packing at last.
The present invention, the use and the safety that fully take into account electric wire are laid equal stress on, and can satisfy the electrical property and the physical property of national electric wire standard code, can make electric wire have environmental protection quality and anti-flammability again, promote the product safety coefficient, reduce the degree of property and loss of life or personal injury.Effectively stop the electric wire spontaneous combustion, or prevent electric wire continuity burning when running into naked light, stop propagation of flame.Electric wire no black smoke in naked light is emerged, and the harmful substance and the toxic gas of generation are few.And manufacturing process is uncomplicated, and insulating barrier and restrictive coating adhesion are strong, in conjunction with the tightness degree height, nylon layer seals no air fully, the surface is moist, rounding is attractive in appearance, when having environmental protection flame retardant, also have well waterproof and dampproof, oil resistant is wear-resisting, characteristic such as corrosion-resistant.
