Abstract

The utility model relates to the technical field of insulated wires, in particular to a three-layer or multi-layer Teflon wire; the wire comprises a wire body, a Teflon extrusion layer and at least two Teflon coatings, wherein the wire body is made of one of an enameled wire, a tinned wire, a silvered wire or a bare copper wire, the Teflon extrusion layer is arranged on the periphery of the wire body and is made of one of ETFE (ethylene tetrafluoroethylene), FEP (fluorinated ethylene propylene) and PFA (Polytetrafluoroethylene), and the Teflon coatings are coated on the periphery of the Teflon extrusion layer; a structure similar to a plastic sheath is sleeved on the periphery of the wire body through an extrusion die, so that the wire body is prevented from being insulated, the performances such as wear resistance and pressure resistance are improved through coating a Teflon coating for many times, the insulation problem of the wire body is not needed to be worried, and more choices can be provided for the coating process, so that the cost is reduced.

Description

Three-layer or multi-layer Teflon wire

Technical Field

The utility model belongs to the technical field of the insulated wire technique and specifically relates to three-layer or multilayer Teflon wire rod.

Background

The application of Teflon to wires with PVC sheaths, such as electric wires, is a prior art, but when the technique is applied to enameled wires, the general coating film formation consistency is poor due to the very small pipe diameter of the enameled wire, and flaws affecting the insulation performance, such as cracks, pinholes and the like, occur with a certain probability. It is generally difficult to apply Teflon coating to the enamel wire.

Disclosure of Invention

Not enough to prior art, the utility model provides a three-layer or multilayer Teflon wire rod.

The technical scheme of the utility model is that:

three-layer or multilayer Teflon wire material, its characterized in that: the wire rod body is one of an enameled wire, a tinned wire, a silvered wire or a bare copper wire, the Teflon extrusion layer is arranged on the periphery of the wire rod body, and the Teflon coating is coated on the periphery of the Teflon extrusion layer.

In one embodiment, the wire body is an enameled wire, the paint layer of the enameled wire is polyester imide paint, known paints which are mainly used for high-grade enameled wires in the market are polyurethane paint, polyester imide paint, polyimide paint and polyamide imide, only the polyester imide paint is widely produced in China at present, and the problem of unstable insulation degree exists, and most of the other paints are imported paint. But apply to the utility model discloses the time, including the Teflon extrusion layer wrapped up the polyester imide paint, the insulation problem has been solved basically to make the enameled wire can adopt domestic paint, reduced manufacturing cost.

In one embodiment, the Teflon extruded layer is 0.0254 to 0.2 mm thick, and any Teflon coating is 0.0254 to 0.2 mm thick.

The Teflon extrusion layer is made of one of ETFE, FEP and PFA.

The utility model has the advantages that: a structure similar to a plastic sheath is sleeved on the periphery of the wire body through an extrusion die, so that the wire body is prevented from being insulated, the performances such as wear resistance and pressure resistance are improved through coating a Teflon coating for many times, the insulation problem of the wire body is not needed to be worried, and more choices can be provided for the coating process, so that the cost is reduced.

In the figure, 1, a wire body; 2. a Teflon extrusion layer; 3. teflon coating.

Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:

as shown in fig. 1, three or more layers of Teflon wire are characterized by: it includes that wire body 1, Teflon extrude layer 2 and two-layer Teflon coating 3 at least, wire body 1 adopts one of enameled wire, tinned wire, silvered wire or bare copper wire, Teflon extrudes layer 2 and sets up in wire body 1 periphery, Teflon coating 3 coating is in Teflon extrudes layer 2 periphery. The Teflon extrusion layer is made of one of ETFE, FEP and PFA.

Example 1

The wire body adopts the enameled wire, the paint layer of the enameled wire adopts the polyester imide paint, the known paint which is mainly used for high-grade enameled wires in the market comprises polyurethane paint, polyester imide paint, polyimide paint and polyamide imide, at present, only the polyester imide paint is widely produced in China, the problem of unstable insulation degree still exists, and most of the other paints adopt imported paint. But apply to the utility model discloses the time, including the Teflon extrusion layer wrapped up the polyester imide paint, the insulation problem has been solved basically to make the enameled wire can adopt domestic paint, reduced manufacturing cost.

Example 2

The Teflon extrusion layer has a thickness of 0.0254 to 0.2 mm, and any one Teflon coating has a thickness of 0.0254 to 0.2 mm.

The foregoing embodiments and description have been provided to illustrate the principles and preferred embodiments of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.

Claims

1. Three-layer or multilayer Teflon wire material, its characterized in that: the wire comprises a wire body, a Teflon extrusion layer and at least two Teflon coating layers, wherein the Teflon extrusion layer is arranged on the periphery of the wire body, and the Teflon coating layers are coated on the periphery of the Teflon extrusion layer; the wire body adopts an enameled wire, and a paint layer of the enameled wire adopts polyester imide paint; the thickness of the Teflon extrusion layer is 0.0254-0.2 mm; the Teflon extrusion layer is made of one of ETFE, FEP and PFA.
