Abstract
The utility model relates to a heat bonding compound enameled copper wire. The heat bonding compound enameled copper wire comprises an inner copper wire core (1) and further comprises a first insulating layer (2), a second insulating layer (3), a self-bonding layer (4) and a lubricating layer (5) which are coated in turn, wherein the first insulating layer (2) is an insulating paint taking a polyamide imide paint as a main body; the second insulating layer (3) is a modified polyester imine insulating paint; the self-bonding layer (4) is a thermosetting polyamide resin paint with heating melting property; and the lubricating layer (5) is a natural paraffin wax. The heat bonding compound enameled copper wire has the advantages that no framework is required for fixing and molding during a coil manufacturing process; the bending resistance, voltage resistance, abrasion resistance and heat resistance properties are better; and a paint film is difficult to break.
Description
[technical field]
The utility model relates to insulated electric conductor or the cable of distinguishing by shape, refers to a kind of heat bonding compound lacquered copper wire especially.
[background technology]
The enamelled wire that coil adopted at deflecting coil of color display, electric tool motor, vehicle wiper motor, bicycle assist motor etc. requires to have stronger shape stability and thermal endurance usually, generally all uses heat bonding compound lacquered copper wire.The heat bonding compound lacquered copper wire of prior art comprises circular copper wire central core, insulating barrier and external coating, and said external coating is a thermal adhesive layer.When making coil, need fixedly moulding of skeleton, and its folding, proof voltage, anti-wear performance and heat resistance are relatively poor, paint film is prone to break.
[summary of the invention]
To the shortcoming of prior art, the purpose of the utility model is to provide a kind of and when making coil, need not fixedly moulding of skeleton, and its folding, proof voltage, anti-wear performance and heat resistance are better, the heat bonding compound lacquered copper wire that paint film is difficult for breaking.
The utility model solves the technical scheme that its technical problem adopted: a kind of heat bonding compound lacquered copper wire is provided, it is characterized in that: first insulating barrier, second insulating barrier, self-adhesive layer and the lubricating layer that include the copper cash inner core and wrap up successively.Said first insulating barrier can be polyamidoimide lacquer for the insulating varnish of main body, second insulating barrier can be modified poly ester imines insulating varnish, self-adhesive layer can be have the thermosetting polyamide lacquer type organic coating that heats melting adhesivity or epoxy material, lubricating layer can be fatty acid wax, natural paraffin wax or synthesizing polyester class.
Through at color television set deflecting coil, deflecting coil of color display, electric tool motor, bicycle assist motor, cold-resistant matchmaker's line, vehicle wiper motor, be applied to C level (long-term work temperature 200'C and following) below the C class F insulation on various motors, the electrical equipment and use and can reach following index:
The relevant temperature in 20000h extrapolation life-span is not less than 200
0C is 220
0Not little dried 5000h of test life-span during C; Thermal shock: 220
0C is 2D 0.5h; The softening puncture: 320 ℃ is 2mim; Unidirectional lacquer>=9N Ji Chuandianya the > that scrapes; 8KV; Paint film is continuous :≤1 (1000V); Nian Heqiangdu>2N; And cold-resistant matchmaker's solvent resistance is outstanding; Anti-basic distortion well; Do not produce pin hole during coiling; Be difficult for suction, the breakdown potential pressure energy remains on initial condition: coil is indeformable in the environment that temperature, humidity change.
The beneficial effect of the utility model is: when making coil, need not fixedly moulding of skeleton, and its folding, proof voltage, anti-wear performance and heat resistance are better, paint film is difficult for breaking.
[description of drawings]
Below in conjunction with accompanying drawing the utility model is done further to describe.
Accompanying drawing is the structural representation of the utility model.
Among the figure: 1 is that copper cash inner core, 2 is that first insulating barrier, 3 is that second insulating barrier, 4 is that self-adhesive layer, 5 is lubricating layer.
[embodiment]
Referring to accompanying drawing, a kind of heat bonding compound lacquered copper wire of the utility model is characterized in that: include copper cash inner core 1 and first insulating barrier 2, second insulating barrier 3, self-adhesive layer 4 and the lubricating layer 5 of parcel successively.
In the embodiment of the utility model, said first insulating barrier 2 are polyamidoimide lacquers for the insulating varnish of main body, second insulating barrier 3 be that modified poly ester imines insulating varnish, self-adhesive layer 4 are that to have the thermosetting polyamide lacquer type organic coating, the lubricating layer 5 that heat melting adhesivity are natural paraffin waxs.
Claims (2)
1. a heat bonding compound lacquered copper wire is characterized in that: first insulating barrier (2), second insulating barrier (3), self-adhesive layer (4) and the lubricating layer (5) that include copper cash inner core (1) and wrap up successively.
2. heat bonding compound lacquered copper wire according to claim 1 is characterized in that: said first insulating barrier (2) be polyamidoimide lacquer for the insulating varnish of main body, second insulating barrier (3) be that modified poly ester imines insulating varnish, self-adhesive layer (4) they are that to have the thermosetting polyamide lacquer type organic coating, the lubricating layer (5) that heat melting adhesivity be natural paraffin wax.
