Abstract
The invention discloses an insulating varnished wire which comprises a metal wire core and an insulating varnish layer coating the outer layer of the metal wire core. A nano insulating layer further covers outside the insulating varnish layer. The insulating varnished wire has the advantages that the nano insulating layer is further attached to the common insulating varnish layer, therefore, the insulating effect is further improved, the nano insulating layer is not just simply attached physically, and further has a modification effect on the common insulating varnish layer, and ageing resistance and corrosion resistance of the insulating varnished wire are improved.
Description
Technical field
The present invention relates to a kind of enamel insulated wire.
Background technology
Enamelled wire is widely used in the fields such as transformer coil, and along with market is more and more higher to the quality requirement of the products such as transformer coil, the quality of enamelled wire especially its insulating properties, ageing-resistant performance etc. also has been subject to the more attention of producers.
Summary of the invention
For solving the deficiencies in the prior art, the object of the invention is to overcome the defect of prior art, a kind of good insulation preformance, ageing-resistant enamelled wire are provided.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of enamel insulated wire comprises: the metal core, be wrapped in the outer field insulation enamelled coating of metal core, and above-mentioned insulation enamelled coating also covers a nanometer insulating barrier outward.
The aforementioned metal core is copper core or thread core of aluminum.
The aforementioned dielectric enamelled coating is polyurethane enamelled coating, polyester enamelled coating or polyester-imide enamelled coating, and its thickness is 1-2mm.
The material of aforementioned nanometer insulating barrier is nanometer polyimide layer or epoxide resin nano, and its thickness is 0.2-1mm.
Also comprise nano titanium oxide in the material of aforementioned nanometer insulating barrier.
Usefulness of the present invention is: enamelled wire of the present invention, adhered to again one deck nanometer insulating barrier outside common insulation enamelled coating, solved the problem that there is pin hole in common insulation enamelled coating, further guaranteed product quality, and the nanometer insulating barrier is not merely simple physical attachment, also common insulation enamelled coating is had to modifying function, improved resistance to ag(e)ing and the corrosion resistance of enamelled wire.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of enamel insulated wire of the present invention.
The implication of Reference numeral in figure: 1, metal core, 2, the insulation enamelled coating, 3, the nanometer insulating barrier.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
Referring to Fig. 1, a kind of enamel insulated wire of the present invention comprises: metal core 1, be wrapped in the outer field insulation enamelled coating 2 of metal core 1, and also cover a nanometer insulating barrier 3 outside insulation enamelled coating 2.Preferably, metal core 1 is copper core or thread core of aluminum.Further, insulation enamelled coating 2 is polyurethane enamelled coating, polyester enamelled coating or polyester-imide enamelled coating, and its thickness is 1-2mm, and the material of nanometer insulating barrier 3 is nanometer polyimide layer or epoxide resin nano, and its thickness is 0.2-1mm.As a kind of improvement, the material of nanometer insulating barrier 3 also comprises nano titanium oxide, to increase the ageing-resistant performance of enamelled wire.
It should be noted that, the insulation enamelled coating is wrapped on the metal core by the dipping lacquer method, and so-called dipping lacquer method, be positioned over insulating varnish in one container exactly, then the metal core is immersed in insulating varnish, and under certain temperature conditions, insulating varnish can be wrapped on the metal core.And the preparation process of nanometer insulating barrier is as follows: at first nano material be scattered in the container that has held alcohol and stirred, then this container submerges the metal core that has wrapped up the insulation enamelled coating, finally carry out the sintering oven dry, so, the nanometer insulating barrier is not merely just that physical attachment is on the insulation enamelled coating, but synergy has occurred with the insulation enamelled coating, also greatly improved ageing-resistant performance when further increasing insulating properties.Experimental results show that, the polyurethane enamelled coating that the metal core is copper core, the enamelled coating that insulate is thickness 1mm, the nano titanium oxide nanometer polyimide layer that the nanometer insulating barrier is 0.2mm, the class of insulation is the R level, be placed in temperature and be 100 ℃, the ageing oven 24h of humidity 80%, without aging phenomenon, greatly be better than on market the enamelled wire without the nanometer insulating barrier.
Above demonstration and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
