Abstract
The invention discloses an aramid-fiber varnished wire, and the varnished wire comprises a conductor. The external surface of the conductor is wrapped by an aramid fiber insulating varnish film. The invention also provides a production method for the aramid-fiber varnished wire. The aramid-fiber varnished wire is excellent in mechanical performance, flame retardation performance, electrical isolation performance, heat resistance performance and chemical corrosion resistance performance, and can be used for a field which exerts stricter requirements on the performances of wires and cables.
Description
Technical field
The present invention relates to a kind of electric wire.
Background technology
At present, the application of electric wire is constantly expanded, more and more harsher to the performance requirement of electric wire, needs electric wire to have the performances such as excellent machinery, electric insulation, fire-retardant, heat-resisting, resistance to chemical attack.
But, still there is no a kind of enamel insulated wire, can solve the problems of the technologies described above well.
Summary of the invention
Goal of the invention is, for the performance of current enamelled wire technical problem excellent not, to propose a kind of high performance aramid fiber enamelled wire.
For reaching above-mentioned purpose, the invention provides a kind of aramid fiber enamelled wire, comprising conductor, the outer surface of conductor is coated with aramid fiber insulation paint film.
Preferably, described conductor is the conductor of single or stranded.
Preferably, described conductor is have coating or the conductor without coating.
Preferably, described conductor is copper, aluminium conductor.
Preferably, described insulation paint film is meta-aramid paint film or p-aramid fiber paint film.
The present invention also provides a kind of production method of aramid fiber enamelled wire, comprises the steps:
Use accurate stranding machine that some diameter 0.07 ~ 0.254mm tinned wirds are twisted into a branch of multiply tin-coated copper twisted wire, it can be used as conductor;
Aromatic diamine and aromatic diacid chlorides are carried out polycondensation reaction in hexamethyl phosphoramide and lithium chloride solvent and makes aramid fiber insulation paint, reaction temperature is 0 ~ 10 DEG C, and the aramid fiber insulation paint mass concentration obtained after reaction is 10 ~ 18wt%; After using die methods that above-mentioned aramid fiber insulation paint is evenly coated in conductive surface, enter baker and carry out the processes such as solvent evaporation, film curing and cooling, enamelled wire is after repeatedly japanning-oven dry-cooling procedure, and form aramid fiber insulation paint film, thickness is 0.2 ~ 0.8mm.
Beneficial effect of the present invention:
1. good mechanical performance: fracture strength is high, percentage elongation is comparatively large, soft handle, and wear-resisting tear-proof.
2. Heat stability is good: can at high temperature Long-Time Service and not aging, its electric property and mechanical performance can keep for a long time, and excellent dimensional stability; Short time be exposed in 300 DEG C of high temperature also can not shrink, brittle, softening or melting.
3. outstanding chemical stability: chemical constitution exceptional stability, can the burn into resistant to hydrolysis effect of the dense inorganic acid of resistance to most height and other chemicals and steam corrosion.
4. splendid electrical insulating property: dielectric constant is very low, intrinsic dielectric strength makes it under high temperature, low temperature, super-humid conditions, all can keep excellent electrical insulating property, breakdown voltage resistant high.
5. excellent anti-flammability.Can not burn in atmosphere, not combustion-supporting yet, there is self-extinguishment.
Accompanying drawing explanation
Fig. 1 is the structural representation of aramid fiber enamelled wire of the present invention.
Number in the figure: 1 conductor, 2 aramid fiber paint film insulating barriers.
Embodiment
By describing technology contents of the present invention, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with execution mode.
Refer to Fig. 1, aramid fiber enamelled wire of the present invention comprises conductor 1, and the outer surface of conductor 1 is coated with aramid fiber insulation paint film 2.
Preferably, described conductor is the conductor of single or stranded.
Preferably, described conductor is have coating or the conductor without coating.
Preferably, described conductor is copper, aluminium conductor.
Preferably, described insulation paint film 2 is meta-aramid paint film or p-aramid fiber paint film.
Aramid fiber enamelled wire of the present invention, when producing, uses accurate stranding machine that 17 diameter 0.16mm tinned wirds are twisted into a branch of multiply tin-coated copper twisted wire, it can be used as conductor 1.
Aromatic diamine and aromatic diacid chlorides are carried out polycondensation reaction in hexamethyl phosphoramide and lithium chloride solvent and makes aramid fiber insulation paint, reaction temperature is 0-5 DEG C, and the aramid fiber insulation paint mass concentration obtained after reaction is 13wt%; After using die methods that above-mentioned aramid fiber insulation paint is evenly coated in conductor 1 surface, enter baker and carry out the processes such as solvent evaporation, film curing and cooling, enamelled wire is after repeatedly japanning-oven dry-cooling procedure, form aramid fiber insulation paint film 2, thickness is 0.4mm, and this insulation paint film ensure that the mechanical performance of wire rod excellence, fire resistance, electrical insulation capability, heat resistance and resistance to chemical corrosion.
In sum, although represented with reference to specific preferred embodiment and described the present invention, it shall not be construed as the restriction to the present invention self.Under the spirit and scope of the present invention prerequisite not departing from claims definition, various change can be made in the form and details to it.
