Abstract
The utility model relates to the technical field of enameled wires, in particular to a special high-temperature resistant enameled wire, which includes a metal wire core, a heat-resistant bottom coating is applied outside the metal wire core, and a heat-resistant surface coating is applied outside the heat-resistant bottom coating. The metal wire core of the utility model adopts a composite coating structure, has perfect performance, higher thermal class, and perfect heat resistance, and meets the high-temperature resistant requirement of products such as a high-temperature motor, a load motor, an air conditioner compressor, a refrigerator compressor and a water dispenser.
Description
Technical field:
The utility model relates to the enamelled wire technical field, particularly a kind of special high temperature-resistant 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; their employed enamelled wires usually turn-to-turn short circuit can occur; temperature rise superelevation and problem such as burn out; the main cause that these problems occur is: the motor winding process requires enamelled wire soft; because motor has the characteristic that works long hours; temperature rise is higher; so also require enamelled wire that higher thermal endurance is arranged; 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 resistant to elevated temperatures requirement in the time of all can not satisfying above-mentioned motor product and normally use.
The utility model content:
The purpose of this utility model is to provide the special high temperature-resistant enamelled wire at the deficiencies in the prior art, and it has advantages such as thermal level height, function admirable.
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.
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 heat-resisting finishing coat is the polyamide-imide 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, and more excellent performance has higher thermal level, excellent heat resistance 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, is coated with heat-resisting priming coat 3 outside the metal core 1, is coated with heat-resisting finishing coat 2 outside the heat-resisting priming coat 3.
The temperature index of the utility model special high temperature-resistant enamelled wire is 200 enamelled wire product, 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, improve thermal level and correlated performance again, thereby can satisfy high-temperature electric machine, load motor, compressor of air conditioner, freezer compressor, the high temperature resistant instructions for use 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.
Must have good self lubricity for compressor with product finishing coat resin tool, common high-temperature electric machine is coated with lubricant with product finishing coat resin surface.
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.
