Abstract
The utility model relates to the technical field of an enamelled wire, in particular to an enamelled wire used for a motor, comprising a metal wire core, wherein the metal wire core is externally coated with a heat-resisting bottom coating which is externally coated with a heat-resisting surface coating; and the heat-resisting surface coating is a polyamide-imide resin layer. The metal wire core externally adopts a compound coating structure, has higher heat level and excellent heat resistance and corona resistance, and can prevent the enamelled wire from being damaged, and meet the use requirement of the motor.
Description
Technical field:
The utility model relates to the enamelled wire technical field, particularly a kind of motor enamelled wire.
Background technology:
At present; high-temperature electric machine; load motor; compressor of air conditioner; freezer compressor; products such as water dispenser all need to use enamelled wire; these products have in the long-time hot operation process all can produce corona; thereby destroy the paint film of enamelled wire; therefore; their employed enamelled wires usually turn-to-turn short circuit can occur; temperature rise superelevation and problem such as burn out; but; the enamelled wire product that generally uses is the enamelled wire of temperature index 180 at present; the enamelled wire product of existing temperature index 180 is generally modified poly ester or polyester imine resin single coating; this resin properties is that tack is good; scratch resistance; breakdown voltage property is good; but, the enamelled wire product of temperature index 180 under existing production technology, the anti-corona the when motor that all can not satisfy the said goods normally uses; resistant to elevated temperatures requirement.
The utility model content:
The purpose of this utility model is that the motor enamelled wire is provided at the deficiencies in the prior art, and it has thermal level height, function admirable, anti-corona, advantage such as high temperature resistant.
For achieving the above object, the utility model adopts following technical scheme:
It comprises the metal core, and the metal core is coated with heat-resisting priming coat outward, and heat-resisting priming coat is coated with heat-resisting finishing coat outward, and heat-resisting finishing coat is the polyamide-imide resin layer.
Wherein, described heat-resisting priming coat is the modified poly ester layer.
Perhaps, described heat-resisting priming coat is the polyester imine resin layer.
Described metal core is a copper core.
The beneficial effects of the utility model are, the metal core adopts composite coating structure outward, more excellent performance, has higher thermal level, excellent heat resistance, can resist corona, prevent that paint film is destroyed, can satisfy the high temperature resistant instructions for use of products such as high-temperature electric machine, load motor, compressor of air conditioner, freezer compressor, water dispenser.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is a schematic cross-section of the present utility model
Wherein, corresponding label and title are:
1---the metal core, 2---heat-resisting finishing coat, 3---heat-resisting priming coat.
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, metal core 1 can be copper core or copper cover aluminum core, are coated with heat-resisting priming coat 3 outside the metal core 1, be coated with heat-resisting finishing coat 2 outside the heat-resisting priming coat 3, heat-resisting finishing coat 2 is the polyamide-imide resin layer.
Described heat-resisting priming coat is the modified poly ester layer, and perhaps, described heat-resisting priming coat is the polyester imine resin layer.
The utility model motor is 200 enamelled wire product with the temperature index of enamelled wire, adopt the modified poly ester or the polyester imine resin of temperature index 200 to make priming coat, both improved heat-resisting, the premium properties that has kept the enamelled wire product of existing temperature index 180 again, finishing coat is the polyamide-imide resin of 220 grades of temperature index, this resin properties is anti-solvent, breakdown voltage property is good, the sliding property in surface is good, so the enamelled wire product of temperature index 200 has the characteristic of temperature index 180 products concurrently, thermal level and correlated performance have been improved again, can resist corona, prevent that the filefish film is destroyed, thereby can satisfy high-temperature electric machine, load motor, compressor of air conditioner, freezer compressor, the instructions for use of the motor of products such as water dispenser.
In addition, the enamelled wire product priming coat of temperature index 200: modified poly ester or polyester imine resin weight account for 70%～80% of whole paint vehicle component, finishing coat: polyamide-imide resin weight accounts for 20%～30%, because the polyamide-imide resin unit cost is generally 160% of polyester-imide, so the finishing coat accounting can reduce production costs heavily less, can also guarantee that serviceability meets the requirements simultaneously.
The enamelled wire product of temperature index 200 is a composite coating, product surface difficulty is accomplished very smoothly, must do technological improvement on the equipment and could satisfy this product requirement, and increasing cooling air quantity, to guarantee that resin bed solidifies good, two rows before and after the japanning roller is necessary for guarantee the composite coating process requirements.
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.
