Abstract

The utility model relates to the technical field of special electromagnetic wires, in particular to a high-temperature resistant special electromagnetic wire, which comprises a metal core, wherein the metal core is coated with an anti-oxidation protective layer, the anti-oxidation protective layer is coated with a self-fluxing enameled layer, the self-fluxing enameled layer is coated with an self-adhesive layer, and the self-adhesive layer is coated with an insulating layer. As the metal core is coated with the anti-oxidation protective layer which is coated with the self-fluxing enameled layer, the special electromagnetic wire has fine anti-oxidation performance, fine film uniformity and stable product quality, can meet requirements of high temperature resistance and has the self-adhesive layer with stable coherence.

Description

Extraordinary electromagnetic wire

Technical field:

The utility model relates to extraordinary electromagnetic wire technical field, particularly resistant to elevated temperatures extraordinary electromagnetic wire.

Background technology:

At present, there are shortcomings such as the paint film consistency is poor, caking property is bad, the peeling operation is long in fire resistant electric wire, because the self-adhesion that existing self-adhesive enameled wire is selected for use coats with lacquer general temperature resistant grade lower (155), so be difficult to adapt to the environment for use of high temperature resistant product, and directly weld the general temperature resistant grade of series products also lower (155), owing to now be generally single stove production with technology, self-adhesion lacquer, straight weldering lacquer are 155 grades, paint film is rounding not, the caking property instability, simultaneously, have under the hot operation condition, occur bad phenomenon such as the oxidation of metal core, embrittlement easily; Comparatively speaking, fire resistant electric wire product thermal level is 180, require quite high to straight weldering lacquer and self-adhesion lacquer, performance should meet the requirements, and satisfies operating characteristic again, can prevent high-temperature oxydation, but, existing product does not all satisfy these requirements, therefore, needs stable, the resistant to elevated temperatures self-adhesive enameled wire of a kind of caking property of design.

The utility model content:

The purpose of this utility model is to provide a kind of resistant to elevated temperatures extraordinary electromagnetic wire, product with stable quality, paint film high conformity at the deficiencies in the prior art, caking property is stable, has anti-oxidation preferably performance, and product shaping is good, effectively promote quality, satisfy instructions for use.

For achieving the above object, the utility model adopts following technical scheme:

It comprises the metal core, and the metal core outside is coated with the protection against oxidation layer, and the protection against oxidation layer outside is coated with straight weldering enamelled coating, directly welds the enamelled coating outside and is coated with self-adhesive layer, and self-adhesive layer is coated with insulating barrier.

Described straight weldering enamelled coating is for can weld the polyester-imide enamelled coating.

Described self-adhesive layer is the hot melt self-adhering enamelled coating.

Described metal core is a copper core.

Described protection against oxidation layer is a silver layer.

The beneficial effects of the utility model are; be coated with the protection against oxidation layer in the outside; the protection against oxidation layer outside is coated with straight weldering enamelled coating; have anti-oxidation preferably characteristics; the paint film high conformity, product with stable quality can satisfy high temperature resistant requirement; and the caking property of self-adhesive layer is stable, and product shaping is good.

Wherein, corresponding label and title are:

1---the metal core, 2---self-adhesive layer, 3---directly weld enamelled coating, 4---the protection against oxidation layer, 5---insulating barrier.

Embodiment:

Below in conjunction with accompanying drawing the utility model is further described.

See accompanying

drawing

1,2, the utility model comprises: metal core 1, and described metal core 1 is a copper core; metal core 1 outside is coated with protection against oxidation layer 4; protection against oxidation layer 4 outside are coated with straight weldering enamelled coating 3, directly weld enamelled coating 3 outsides and are coated with self-adhesive layer 2, and self-adhesive layer 2 is coated with insulating barrier 5.

Described straight weldering enamelled coating 3 is for can weld the polyester-imide enamelled coating.

Described self-adhesive layer 2 is the hot melt self-adhering enamelled coating.

Described protection against oxidation layer 4 is a silver layer.

The utility model fire resistant special type electromagnetic wire is the composite bed product, baker production before and after needing, and baker cures the straight layer of priming paint before the configuration, and back baker cures the finish paint self-adhesive layer; Priming paint selects the welded polyester-imide lacquer of 180 grades of thermal levels, the viscosity equilibrium, and finish paint is 155 grades of hot melt self-adhering paints, softening temperature height again.

In the course of processing, priming coat adopts die methods for felt method japanning, the above specification of finishing coat 0.150mm, guarantees the paint film rounding, and consistency is good; Adopt the dielectric loss instrument to determine OK range on the enamelling technique, guaranteed quality is stable; The two bakers of configuration, the front and back formula can be produced mill run, but production fire resistant electric wire again; Finishing coat configuration solvent pump is guaranteed viscosity stabilization, the paint film equilibrium; Storage environment guarantees that tack coat is normal in 25 ℃～35 ℃, the no phenomenon of bonding naturally.

The utility model can be effectively anti-oxidation, and result of use is better.

Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
