Description
Technical field
The present invention relates to a kind of enamel-covered wire, particularly a kind of high-temperature resistant enamelled wire.
Background technology
Along with the fast development of China's electronics technology sector, the integral level of enamel-covered wire industry also obtains
Having arrived good raising, enamel-covered wire is widely used in each electronic applications.Existing enamel-covered wire
It is typically to form by a circular conductor and at the paint of the outer coated with multiple layer difference in functionality of conductor, rises
Arrive and external insulation and resistant to elevated temperatures effect, the paint temperature resistant grade selected due to existing enamel-covered wire
Relatively low, so being difficult to adapt to the use environment of high temperature resistant products, under high temperature operating conditions, by
In metal core and paint all can expanded by heating, produce corresponding stress, so can cause metal wire
Can depart between core and enamelled coating or between enamelled coating, the oxidation of metal core easily occur, sends out
The bad phenomenon such as crisp, resistant to elevated temperatures paint is coated on conductor, due to conductive surface smoother,
The paint film being coated in its surface is easily broken after by high temperature or violent motion and comes off, separately
Not enough due to the lubricity of existing enamel-covered wire outward, the paint film on its surface when carrying out high-speed winding
Easily abrasion, even can drop.Therefore, existing enamel-covered wire also exist resistance to elevated temperatures poor,
The problems such as paint film adhesion property is poor, the speed of the second-rate and coiling of enamel-covered wire is slower.
Summary of the invention
It is an object of the invention to, it is provided that a kind of high-temperature resistant enamelled wire.It has the most high temperature resistant
Performance, improve paint film adhesion property, improve the quality of enamel-covered wire product and improve around
The feature of linear velocity.

In aforesaid a kind of high-temperature resistant enamelled wire, described first anti-slip tank, the second anti-slip tank, the
Three anti-slip tanks and the 4th anti-slip tank are arc-shaped structure.
Compared with prior art, the present invention is sequentially coated with modified poly ester at metal wire core outer surface
Enamelled coating, polyester-imide enamelled coating, polyamidoimide enamelled coating and nylon enamelled coating, and according to it not
With the performance of enamelled coating, the thickness of each enamelled coating is made concrete restriction so that the structure of enamel-covered wire
Performance is uniform and stable, has preferable resistance to elevated temperatures.By at metal core, modified poly ester
The outer surface of enamelled coating, polyester-imide enamelled coating and polyamidoimide enamelled coating arranges the anti-skidding of circular arc
Groove, enamelled coating is filled in corresponding anti-slip tank accordingly, add adjacent enamelled coating and enamelled coating and
Coefficient of friction between enamelled coating and metal core, improves the adhesion property of paint film；Meanwhile, by
Corresponding flatulence of heat type phenomenon can be produced by high temperature in enamelled coating and metal core, by arranging anti-slip tank,
The stress produced by flatulence of heat type can be alleviated so that be connected between enamelled coating with metal core in inside
More tight, will not make to depart between enamelled coating, it is ensured that the Stability Analysis of Structures within enamel-covered wire,
Make it have good resistance to elevated temperatures, it is ensured that enamel-covered wire has good serviceability.Logical
Cross and nylon enamelled coating is set at outermost layer, the greasy property of enamel-covered wire can be increased so that enamel-covered wire
Coiling at a high speed can be carried out, be provided with anti-simultaneously between nylon enamelled coating and polyamidoimide enamelled coating
Chute so that enamel-covered wire is when high-speed winding, and nylon enamelled coating is without departing from enamel-covered wire.To sum up institute
Stating, the present invention has preferable resistance to elevated temperatures, the adhesion property improving paint film, improves enamel-cover
The quality of line product and improve the feature of threading speed.
