Abstract
The utility model provides a three-coating layer enameled wire with a nylon outer layer. The three-coating enameled wire with the nylon outer layer includes an inner copper conductor and coating layers wrapping the inner copper conductor, wherein the coating layers includes a polyester-imide inner layer, a polyamide-imide middle layer, and the nylon outer layer. According to the three-coating enameled wire with the nylon outer layer of the utility model, three coating layers in different materials are coated on the inner copper conductor, thickness and coating times of each coating layer being limited accurately, and therefore, a high-quality enameled wire can be obtained; and further, the outmost coating layer of the enameled wire is a nylon layer, and therefore, the enameled wire has excellent lubrication property and is low in cost.
Description
Technical field
The utility model relates to the enamelled wire field, and particularly a kind of skin is three coating enamelled wires of nylon.
Background technology
Enamelled wire is a principal item of winding wire, is comprised of conductor and two ones of insulating barriers, and bare wire forms through repeatedly painting, curing behind annealing softening again.Along with the development of the manufacturings such as torquer, motor, transformer, engine, the continuous variation of applied environment and the continuous progress of science and technology, the enamelled wire that needs different performance in increasing occasion, there are a lot of enamelled wires that its greasy property is had very high requirement, the present enamelled wire that uses, the enameled wire surface lubricating performance is not good especially, enamelled wire scratches easily during the high-speed winding machine coiling, is difficult to guarantee product quality.
The someone expects applying two different coating at enamelled wire for this reason, and is still along with the development of society, more and more higher to the enameled wire performance requirement to reach corresponding quality index, only applies 2 layers of resulting enameled wire performance and often do not reach requirement.
Along with the continuous upgrading of the continuous Development Technology of science and technology to each layer coating thickness with after applying number of times and accurately limiting, three coat enamelled wires have become possibility, three coat enamelled wires are except each layer coating thickness and coating number of times should be noted that, the selection of each coat material is also played crucial important to enameled wire performance, because the surface lubrication performance of enamelled wire is decided by outermost layer coat material, the quality of enamelled wire is better after the better high-speed winding machine coiling of the surface lubrication performance of enamelled wire, so the selection of enamelled wire outermost layer coat material seems particularly important.
Nylon has good greasy property, compares with other coats, and price neither be very expensive, therefore selects it high as outermost layer coat cost performance.
The utility model content
For above problem, the utility model is by designing three coating enamelled wires that a kind of skin is nylon, it applies the different coat of three-layer-material and thereby each layer coating thickness and coating number of times is accurately limited the enamelled wire that can obtain the high-quality performance at interior copper conductor, this patent enamelled wire outermost layer coat is nylon layer in addition, thereby there are splendid greasy property and cost not high, for reaching this purpose, it is three coating enamelled wires of nylon that the utility model provides a kind of skin, the coat that comprises copper conductor in interior copper conductor and the parcel, described coat has three layers, internal layer is the polyester-imide layer, and the middle level is the polyamidoimide layer, and skin is nylon layer.
As further improvement of the utility model, described interior copper conductor is the circle copper conductor, and described interior copper conductor is flat cable copper conductor, also can be used for flat cable copper conductor because this patent accurately limits so namely can be used for the circle copper conductor each layer coating thickness and coating number of times.
As further improvement of the utility model, described internal layer coat thickness is 6 μ m, shows that after tested this patent internal layer coat thickness can only be 6 μ m, because the enamelled wire gross thickness limits, thickness is crossed thin meeting affect enameled wire performance, blocked up other coat thickness that then can affect of thickness.
As further improvement of the utility model, described internal layer coat japanning number of times is 8-9 time and since material restriction and thickness limits as calculated this patent internal layer coat number of times of painting should be 8-9 time.
As further improvement of the utility model, described middle level coat thickness is 12-16 μ m, show that after tested this patent middle level coat thickness is 12-16 μ m, because the enamelled wire gross thickness limits, thickness is crossed thin meeting affect enameled wire performance, the blocked up outermost layer coat thickness that then can reduce of thickness.
As further improvement of the utility model, described middle level coat japanning number of times is 2 times and since material restriction and thickness limits as calculated this patent middle level coat japanning number of times should be 2 times.
As further improvement of the utility model, described outer coat thickness is 2 μ m, shows that after tested the outer coat thickness of this patent is 2 μ m, because the enamelled wire gross thickness limits, outermost layer coat thickness is 2 μ m as calculated.
As further improvement of the utility model, described outer coat japanning number of times is 1 time and since material restriction and thickness limits as calculated the outer coat japanning of this patent number of times should be 1 time.
The utility model is that a kind of skin is three coating enamelled wires of nylon, apply the polyester-imide layer at interior copper conductor, polyamidoimide layer and nylon layer, thereby this patent carries out test of many times to each layer coating thickness and applies number of times accurately limiting the enamelled wire that can obtain the high-quality performance according to three layers of coat material difference, this patent also utilizes the outstanding characteristics of nylon low price greasy property in addition, at enamelled wire outermost layer coating nylon layer, thereby there are splendid greasy property and cost not high, can be so that the enamelled wire surface coefficientoffrictionμ be reduced to 0.6-0.8 by original 0.9-1.0.
