Abstract
The invention relates to a low smoke zero-halogen nylon wire. A production method of the low smoke zero-halogen nylon wire comprises the following steps: 1) heating a headpiece; 2) preheating low smoke zero-halogen plastic; 3) paying off; 4) extruding and cladding zero halogen plastic and nylon; and 5) drying and winding up. The environment-friendly low smoke zero-halogen plastic has good flame retardant efficiency, can effectively prevent the spontaneous combustion of the wire, or prevent the continual fire of the wire when meeting open fire, and prevent the fire from spreading. The wire can not generate black smoke when meeting open fire, and the generated hazardous substance and poisonous gas are extremely less. The smoke density is not larger than 250 in a flameless state, and is not larger than 100 in a flame state; the oxygen index is not less than 30%; the release content of the hydracids gas is not larger than 5mg/g; and the pH value is not less than 4.3. The electrical property and physical property can meet the rule of the country wire standard, such as insulation resistance, conductor resistance, strength of extension and elongation at break.
Description
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
Along with the development of society, people are to the reinforcement of environmental consciousness, and the requirement of project quality is further improved, and the requirement of personal safety, fire-fighting is also improved constantly, so have higher requirement to these auxiliary products in market.
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, namely 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 the environmental protection of existing electric wire product and the defective of secure context, the object of the present invention is to provide a kind of low smoke and zero halogen nylon electric wire, the production of this environment-friendly type electric wire is similar to the production method of nylon electric wire, 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.Can satisfy 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.
Technical scheme of the present invention realizes in the following manner: low smoke and zero halogen nylon electric wire,
Its production method may further comprise the steps: 1) head is heated; 2) low smoke and zero halogen plastics preheating; 3) unwrapping wire; 4) Halogen plastics and nylon are extruded coating; 6) dry take-up; It is characterized in that:
1), head is heated: at first 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 260-280 ℃; 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), Halogen plastics and nylon are extruded coating: environmental protection low smoke and zero halogen plastics and nylon are extruded simultaneously, be coated on the copper conductor core of electric wire, electric wire environmentally-friendly plastic after the coating is at internal layer, nylon is at skin, the characteristic of environmentally-friendly plastic determines extruding of electric wire and coating speed can not be too fast, generally is no more than 80 meters/minute.
The present invention, 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.Electric wire no black smoke in naked light is emerged, and harmful substance and the toxic gas of generation are few.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 electrical property of this electric wire routine and physical property satisfy the regulation of national electric wire standard, as insulation resistance, conductor resistance, tensile strength, elongation at break etc.
Embodiment
Low smoke and zero halogen nylon electric wire, its production method may further comprise the steps:
1, head is heated: at first 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 260-280 ℃; 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, Halogen plastics and nylon are extruded coating: environmental protection low smoke and zero halogen plastics and nylon are extruded simultaneously, be coated on the copper conductor core of electric wire, electric wire environmentally-friendly plastic after the coating is at internal layer, nylon is at skin, the characteristic of environmentally-friendly plastic determines extruding of electric wire and coating speed can not be too fast, generally is no more than 80 meters/minute.
Product of the present invention can satisfy 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 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.
