Abstract
The utility model discloses an insulated enamelled wire, comprising a metal wire core, an insulating paint layer wrapping outside the metal wire core, and a nanometer insulating layer covering on the insulating paint layer. Beneficial effects are that the enamelled wire is attached with the nanometer insulating layer outside the ordinary insulating paint layer, so insulation effect is further improved, and the nanometer insulating layer is not just simply attached on the insulating paint layer in a physical manner, but also has modification effect on the ordinary insulating paint layer, and ageing resistance and corrosion resistance of the enamelled wire are improved.
Description
Technical field
The utility model 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. has also been subject to the more attention of producers.
Summary of the invention
For solving the deficiencies in the prior art, the purpose of this utility model is to overcome the defect of prior art, and a kind of good insulation preformance, ageing-resistant enamelled wire are provided.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
An enamel insulated wire, comprising: 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.
Aforementioned metal core is copper core or thread core of aluminum.
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.
In the material of aforementioned nanometer insulating barrier, also comprise nano titanium oxide.
Usefulness of the present utility model is: enamelled wire of the present utility model, at common insulation enamelled coating, adhered to again one deck nanometer insulating barrier outward, solved the problem that common insulation enamelled coating exists pin hole, further guaranteed product quality, and 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.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of enamel insulated wire of the present utility model.
The implication of Reference numeral in figure: 1, metal core, 2, insulation enamelled coating, 3, nanometer insulating barrier.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
Referring to Fig. 1, a kind of enamel insulated wire of the present utility model, comprising: metal core 1, be wrapped in the outer field insulation enamelled coating 2 of metal core 1, and outside insulation enamelled coating 2, also cover a nanometer insulating barrier 3.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, insulation enamelled coating is wrapped on metal core by dipping lacquer method, and so-called dipping lacquer method, is positioned over insulating varnish in one container exactly, then metal core is immersed in insulating varnish, and under certain temperature conditions, insulating varnish can be wrapped on metal core.And the preparation process of nanometer insulating barrier is as follows: first nano material be scattered in the container that has held alcohol and stir, then this container submerges the metal core that has wrapped up insulation enamelled coating, finally carry out sintering oven dry, so, nanometer insulating barrier is not merely just that physical attachment is on insulation enamelled coating, but there is synergy with insulation enamelled coating, when further increasing insulating properties, also greatly improved ageing-resistant performance.Experimental results show that, metal core is that copper core, insulation enamelled coating are the polyurethane enamelled coating of thickness 1mm, the nano titanium oxide nanometer polyimide layer that nanometer insulating barrier is 0.2mm, the class of insulation is R level, be placed in temperature and be 100 ℃, the ageing oven 24h of humidity 80%, without aging phenomenon, be greatly better than on market the enamelled wire without nanometer insulating barrier.
More than show and described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection range of the present utility model.
