Abstract
The utility model relates to the field of insulating a conductor or a cable with a coating composition and especially relates to a self-adhesive enameled wire for a rotor. The technical scheme adopted in the utility model is as follows: the self-adhesive enameled wire comprises a conductor (1) having a circular section and a composite paint film layer coated on the outer surface of the conductor (1); the self-adhesive enameled wire is characterized in that the composite paint film layer is composed of priming paint (2), middle paint (3) and finishing paint (4); and the priming paint (2) is coated on the outer surface of the conductor (1), the middle paint (3) is coated on the outer surface of the priming paint (2), and the finishing paint (4) is coated on the outer surface of the middle paint (3). The self-adhesive enameled wire for the rotor has the following beneficial effects: 1) a coil does not deform at the working temperature of 150 DEG C or above when the rotor uses the enameled wire of the utility model; and 2) by using the enameled wire of the utility model, the overall size of the rotor is reduced, and the overall size of a motor is reduced.
Description
Technical field
The present invention relates to use coating composition to make the field of conductor or cable insulation, especially belong to a kind of rotor self-adhesive enameled wire.
Background technology
Enamelled wire is a principal item of winding wire, is made up of conductor and insulating barrier two parts, and bare wire passes through the mould japanning again behind cold rolling, drawing, annealing softening, cures to form.Self-adhesive enameled wire uses on motor stator at present, because stator temperature rise is low, requires lower.But rotor can not use Self-binding cord, because rotating speed 20000-30000 changes, temperature rise, Self-binding cord more than 150 ℃ cohesive force sharply descend, lose cohesive force between line and the line, cause line bag dilatancy.
Summary of the invention
The object of the present invention is to provide a kind of three layers of paint film self-adhesive enameled wire, use on rotor, can guarantee that the line bag is indeformable when 150 ℃ and above working temperature.
The technical solution used in the present invention is: it comprises cross sectional shape is circular conductor (1) and the composite paint film layer that coats at conductor (1) outer surface, and it is characterized in that: described composite paint film layer is made up of priming paint (2), middle lacquer (3) and finish paint (4); And described priming paint (2) is the outer surface that is coated on conductor (1), and described middle lacquer (3) is the outer surface that is coated on priming paint (2), and described finish paint (4) is the outer surface that is coated on middle lacquer (3).
Beneficial effect of the present invention is: 1, the present invention has adopted mould accurately to apply, and has good tack, the dimensional accuracy height; 2, use the described enamelled wire of invention, can be by heating processes such as energising heating, baking oven heating, hot air circulation heating, make line bag rapid shaping, environment is not polluted, traditional handicraft is common enamelled wire more than 130 grades, needs dipping lacquer, and molding time is long, contain a large amount of solvents in the impregnating varnish simultaneously, operative employee's health is caused have a strong impact on; 3, rotor uses the described enamelled wire of invention, and is indeformable at 150 ℃ and above working temperature line bag; 4, the rotor overall dimensions descends the overall volume of dwindling motor behind the described enamelled wire of use invention.

Embodiment
The invention will be further described below in conjunction with accompanying drawing.
Be illustrated in figure 1 as principle of the invention figure, it is circular conductor (1) and the composite paint film layer that coats at conductor (1) outer surface that the present invention comprises cross sectional shape, and it is characterized in that: described composite paint film layer is made up of priming paint (2), middle lacquer (3) and finish paint (4); And described priming paint (2) is the outer surface that is coated on conductor (1), and described middle lacquer (3) is the outer surface that is coated on priming paint (2), and described finish paint (4) is the outer surface that is coated on middle lacquer (3).
The thickness of the priming paint described in the present invention (2) is the 45%-55% of composite paint film layer thickness; The thickness of lacquer (3) is the 15%-25% of composite paint film layer thickness in described, and the thickness of described finish paint (4) is the 25%-35% of composite paint film layer thickness.
The diameter of the conductor described in the present invention (1) is 0.10mm-2.0mm.
The material of the priming paint described in the present invention (2) is modified poly ester or polyester imine resin lacquer; The material of lacquer (3) is the polyamide-imide resin lacquer in described, and the material of described finish paint (4) is the self-adhesion lacquer.
Rotor self-adhesive enameled wire of the present invention, roll by the conductor in the middle of the enamelled wire is adopted-La-annealing handles, and makes conductor size reach high accuracy, reduces the surface of conductors defective, by mold painting, cures, and cools off, and rolling is finished.Mold painting has accurately been controlled the apparent size of product, and whole technology controlled by computer, has guaranteed the consistency of the performance of product.
