Abstract
The invention discloses an insulation enameled wire. The insulation enameled wire successively comprises a metal wire core, an inertia protection layer, a wear-resistant insulating layer and an insulation varnish layer from the inside to the outside. The wear-resistant insulating layer is a nylon surface layer dipped with an epoxy resin; the components of an insulation varnish comprise polyimide, namometer silicon dioxide, mica powder, an anti-oxidant1010, and decabromodiphenylethane. According to the invention, through a nylon surface layer wrapped by a dipping high temperature resistant modified epoxy resin epoxy resin, the heat resistance, wear resistance and electrical insulation properties of the insulation enameled wire are improved; and through the reasonable design of the formula of the wire varnish of the enameled wire, the varnish layer is provided with excellent high temperature resistance performance, wear resistance and insulating performance. The enameled wire, through the design of a double-layer insulation and wear-resistant layer, can fully satisfy the requirements for high temperature resistance, insulating performance and wear resistance performance in a long-term electric friction environment.

Background technology
Enamelled wire is a kind of electrical material, and it is normally prepared from by the wire enamel of a circular copper line surface processing thin layer, and this wire enamel plays the effect with external insulation.But enamelled wire will be used conventionally under the condition of long-time energising and friction, and conventional wire enamel can not meet the aging and wear-resisting loss of continuous high temperature at present, cause enamelled wire easily to damage and conduct electricity, affect the normal work of machine.
The enamelled wire using exists.。In motor continuous running process, in winding, galvanization and constantly rotation, can produce amount of heat, therefore requires insulating material to be difficult for aging by withstand high temperatures environment.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of enamel insulated wire, can meet the requirement to resistance to elevated temperatures, insulation property and anti-wear performance under long-term energising friction environment.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of enamel insulated wire is provided, comprise successively from inside to outside: metal core, inertia protective layer, abrasion-proof insulating layer and insulation enamelled coating, the nylon surface layer that described abrasion-proof insulating layer is epoxy resin-impregnated; The composition of described insulating varnish comprises: polyimides, nano silicon, mica powder, antioxidant 1010 and TDE.
In a preferred embodiment of the present invention, described metal core is copper cash, aluminum steel, copper-clad aluminum conductor, aluminium copper-clad line, aluminum-magnesium alloy wire or CCAM.
In a preferred embodiment of the present invention, described inertia protective layer is nickel coating.
In a preferred embodiment of the present invention, described epoxy resin is high temperature resistant modified epoxy resin.
In a preferred embodiment of the present invention, each ingredients weight parts of described insulating varnish consists of: 10～50 parts of 80～100 parts of polyimides, 10～30 parts of nano silicons, 10～20 parts of mica powders, 1～5 part of antioxidant 1010 and TDEs.
