Abstract
It is an object of the invention to provide the production technology of a kind of low-fume non-bittern flame-retardant electrical wire, by protective cover material the most processed and copper core, retell protective cover material to be coated on outside copper core thus the electric wire that forms low-smoke non-halogen flame-retardant, protective cover material needs preheating before using mixing and molding, and cladding, it is ensured that the performance of the low-smoke non-halogen flame-retardant of protective cover material, the copper wire of copper core carries out secondary drawing, finally being twisted into core, prepared electric wire has the low-smoke and flame retardant performance of excellence, it is adaptable in production.
Description
Technical field
The present invention relates to the production field of electric wire, particularly relate to the production technology of a kind of low-fume non-bittern flame-retardant electrical wire.
Background technology
My company mainly produces wire and plug line, the raw material of electric wire to be produced, then by raw material and stranded copper cash bag
Overlay on and form electric wire together.This type of plug cord is for products such as air-conditionings.The fire caused because of electric wire, cable aging at present
Calamity also gets more and more, how to reduce the incidence rate of fire and breaking out of fire time mortality rate, low cigarette, Halogen, fire-retardant, environmental protection are also
Become the developing direction of wires and cables industry, need electric wire to have good low-smoke and flame retardant performance.It is thus desirable to a kind of low smoke and zero halogen
The production technology of fire-resistant wire.Therefore solve the problems referred to above and just seem the most necessary.
Summary of the invention
For solving the problems referred to above, the present invention provides the production technology of a kind of low-fume non-bittern flame-retardant electrical wire, is protected by system respectively
Jacking and copper core, retell protective cover material and be coated on outside copper core thus the electric wire that forms low-smoke non-halogen flame-retardant, and protective cover material uses
Preheating is needed, it is ensured that the performance of the low-smoke non-halogen flame-retardant of protective cover material, the copper wire of copper core carries out secondary before mixing and molding, and cladding
Draw, be finally twisted into core, prepared electric wire have excellence low-smoke and flame retardant performance, solve in background technology occur ask
Topic.
It is an object of the invention to provide the production technology of a kind of low-fume non-bittern flame-retardant electrical wire, include following steps:
Step one: make low-smoke halogen-free flame-retardant sheath material: first various raw material weighing high kneadings closed, carry out mixing one-tenth afterwards
Type, then cool down, finally pulverize and be a granulated into protective cover material；
Step 2: make copper core: first being drawn greatly by the copper cash that buying comes, the copper cash being pulled through greatly draws in carrying out, thus draws
Become the copper wire of required diameter, afterwards 12-18 stock copper wire is twisted into copper core；
Step 3: put into by protective cover material in cladding extruding machine, afterwards by copper core traction to cladding extruding machine, by protective cover material bag
Overlay on copper core surface, thus become the electric wire of low-smoke non-halogen flame-retardant, be cooled to conveying afterwards, carry out afterwards printing coding,
Last take-up rolling；
Step 4: the low-fume non-bittern flame-retardant electrical wire made carries out combustion testing, resistance to combustion test, and pin flame is tested, and corrosion resistant
Erosion test.
Further improvement is that: before described step 2 copper wire is stranded, carry out heating anneal.
Further improvement is that: before described step 3 copper core cladding, carry out heating anneal.
Further improvement is that: described protective cover material needs aeration-drying to preserve, and 4 need to be preheated at 5 DEG C of 60 soil before cladding
H removes moisture removal.
Beneficial effects of the present invention: the present invention passes through protective cover material the most processed and copper core, retells protective cover material and is coated on copper cash
Outside core thus form the electric wire of low-smoke non-halogen flame-retardant, protective cover material use mixing and molding, and be coated with before need preheating, it is ensured that sheath
The performance of the low-smoke non-halogen flame-retardant of material, the copper wire of copper core carries out secondary drawing, is finally twisted into core, and prepared electric wire has
Excellent low-smoke and flame retardant performance, it is adaptable in production.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, this embodiment
It is only used for explaining the present invention, is not intended that limiting the scope of the present invention.
The present embodiment provides the production technology of a kind of low-fume non-bittern flame-retardant electrical wire, includes following steps:
Step one: make low-smoke halogen-free flame-retardant sheath material: first various raw material weighing high kneadings closed, carry out mixing one-tenth afterwards
Type, then cool down, finally pulverize and be a granulated into protective cover material；
Step 2: make copper core: first being drawn greatly by the copper cash that buying comes, the copper cash being pulled through greatly draws in carrying out, thus draws
Become the copper wire of required diameter, afterwards 16 strands of copper wires are twisted into copper core；
Step 3: put into by protective cover material in cladding extruding machine, afterwards by copper core traction to cladding extruding machine, by protective cover material bag
Overlay on copper core surface, thus become the electric wire of low-smoke non-halogen flame-retardant, be cooled to conveying afterwards, carry out afterwards printing coding,
Last take-up rolling；
Step 4: the low-fume non-bittern flame-retardant electrical wire made carries out combustion testing, resistance to combustion test, and pin flame is tested, and corrosion resistant
Erosion test.
Heating anneal is carried out before described step 2 copper wire is stranded.Heating anneal is carried out before described step 3 copper core cladding.
Described protective cover material needs aeration-drying to preserve, and need to preheat 4 h at 60 DEG C and remove moisture removal before being coated with.
By protective cover material the most processed and copper core, retell protective cover material be coated on outside copper core thus formed low smoke and zero halogen resistance
The electric wire of combustion, protective cover material needs preheating before using mixing and molding, and cladding, it is ensured that the performance of the low-smoke non-halogen flame-retardant of protective cover material,
The copper wire of copper core carries out secondary drawing, is finally twisted into core, and prepared electric wire has the low-smoke and flame retardant performance of excellence, is suitable for
In producing.
