Embodiment Construction

[0010] A self-adhesive enameled wire as shown in FIG. 1 includes a copper wire 1 and a polyurethane varnish insulating layer 2 coated thereon, and a self-lubricating self-adhesive varnish layer 3 is also covered on the surface of the polyurethane varnish insulating layer 2 .

[0011] The chemical composition of the self-lubricating self-adhesive paint in the self-lubricating self-adhesive paint layer 3 and the concentration percentage content of each composition are: polyamide resin 10%~13%, cresols 33%~36%, phenols 33% ~36% and xylene 15%~18%.

[0012] Compared with the existing ordinary self-adhesive enameled wire, the surface of the self-adhesive enameled wire of the present invention has stronger scratch resistance and better slipperiness, so it is closer to the mechanical properties of the enameled wire proposed by the modern motor industry. higher requirements.

[0013] The self-adhesive enameled wire of the present invention is suitable for winding voice coils of vario...

Abstract

The invention relates to an electric material, in particular to a self-adhesive enameled wire, comprising a copper conductor and a polyurethane paint insulating layer which is coated on the outside of the copper conductor, wherein, a self-lubricating self-adhesive paint layer is also coated on the surface of the polyurethane paint insulating layer; chemical compositions and concentration percentage contents of various compositions of self-lubricating self-adhesive paint in the self-lubricating self-adhesive paint layer are as follows: amilan polyamide resins of 10 percent to 13 percent, cresols of 33 percent to 36 percent, phenols of 33 percent to 36 percent and xylene of 15 percent to 18 percent. Compared with the prior common self-adhesive enameled wire, the surface of the self-adhesive enameled wire has stronger scratch resistance and better gliding property, thereby the self-adhesive enameled wire is in accordance with high requirements provided by the modern electric machine industry to the enameled wire in the aspect of mechanical features.

Description

technical field [0001] The invention relates to an electrical material, in particular to a self-adhesive enameled wire. Background technique [0002] At present, the motor manufacturing industry generally adopts high-speed automatic winding equipment to wind motor coils, so high requirements are put forward for various mechanical properties of enameled wires. High-speed automatic winding equipment requires enameled wires to have certain mechanical strength, and the surface has strong resistance. Abrasion resistance, scratch resistance and good slip. Ordinary enameled wires are no longer able to meet this requirement. Contents of the invention [0003] The technical problem to be solved by the invention is: in order to overcome the deficiencies of the prior art, the invention provides a self-adhesive enameled wire more suitable for use in the modern motor industry. [0004] The technical solution adopted by the present invention to solve the technical problem is: a self-a...
