Abstract

Electric wire and heating wire were sheathed with polytertrafluoro ethlyene tape for anti-chemicals, anti-thermals and electric-insulation properties. Thus, the polytetrafluoro ethylene tape was helically wound on wire or heating wire(1), passed through pipe(3) which is heated to 550-650≰C at 5-7 m/sec and cooled to obtain polytetrafluoro ethylene tape-sheathed electric wire or heating wire.

Description

전선 또는 전열선의 불소수지 피복방법Fluorine resin coating method of electric wire or heating wire

제1도는 본 발명의 제1공정인 불소수지 테이프의 나선상 권취상태를 나타낸 도면이고,1 is a view showing a spiral wound state of the fluororesin tape of the first step of the present invention,

제2도는 제1도에서 테이프로 권취한 전선을 열처리하는 실시예시도이다.2 is an exemplary view of heat treating a wire wound with a tape in FIG.

본 발명은 전선이나 각종 전열선에 내열성, 내약품성 및 전기 절연성을 부여하기 위하여 폴리 4블화 에틸렌(polytetrafluoro ethylene, 이하 TFE라 한다) 테이프를 피복하여서 된 전선 및 전열선의 불소수지 피복방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for coating fluorine resins on electric wires and heating wires by coating a polytetrafluoroethylene (hereinafter referred to as TFE) tape to impart heat resistance, chemical resistance and electrical insulation to electric wires and various heating wires.

종래에는 전선 또는 전열선에 실리콘수지, PVC 또는 고무등으로 피복한 것이 있으나 내열성, 내약품성 및 전기절연성 등을 만족할 수 없는 결점이 있었고, 더우기 종래의 불소수지 피복방법에 있어서는 불소수지를 용융하여 압출 성형하는 방법이 있었으나, 불소수지의 성질상 융점 이상의 용융상태에서는 유용성이 없기 때문에 다른 합성수지에 비하여 기술적으로 많은 문제점이 있어 생산성이 저하되는등의 결점이 있다.Conventionally, the electric wire or heating wire is coated with silicone resin, PVC or rubber, but it has a defect that cannot satisfy heat resistance, chemical resistance and electrical insulation. Furthermore, in the conventional fluorine resin coating method, extrusion molding is performed by melting fluorine resin. There is a method, but due to the nature of the fluorine resin is not useful in the molten state above the melting point, there are many technical problems compared to other synthetic resins, there is a disadvantage that the productivity is lowered.

본 발명은 이와 같은 종래의 결점을 해결하기 위한 것으로서,The present invention is to solve such a conventional drawback,

종래의 압출방법이 아닌 불소수지로 만든 내열, 내약품성 및 절연성 테이프를 전선 또는 전열선 표면에 나선상으로 권취 피복한 다음 융점 이상의 온도로 가열하여 융착시키는 것을 특징으로 하는 것으로 본 발명의 기술적 구성을 공정에 따라 상술하면 다음과 같다.The technical configuration of the present invention is characterized in that the heat-resistant, chemical-resistant and insulating tape made of fluorine resin, not the conventional extrusion method, is wound on a wire or heating wire surface in a spiral shape and then heated and fused to a temperature above the melting point. According to the detailed description as follows.

[제1공정][Step 1]

전선 또는 전열선(1)의 표면에 TFE로 만든 테이프(2)를 기계적 방법으로 나선상으로 균일하게 권취한다.The tape 2 made of TFE is wound on the surface of the electric wire or the heating wire 1 uniformly in a spiral manner by a mechanical method.

[제2공정][Step 2]

제1공정에서 나선상으로 피복된 전선 또는 전열선(1)을 TFE로 제조된 테이프(2)가 융점 이상으로 가열되면 용융되면서 응축하는 성질을 이용하여 550-650℃로 유지되는 파이프관(3)내를 5-7m/ses 가열통과시켜 냉각시키므로서 본 발명의 피복전선이 제조된다.In the pipe tube 3, which is maintained at 550-650 ° C by using a property of melting and condensing the wire 2 or the heating wire 1 coated with a spiral in the first step above the melting point when the tape 2 made of TFE is heated above the melting point. The coated wire of the present invention is prepared by cooling the solution by passing through 5-7 m / ses.

이와 같이 된 본 발명의 작용효과를 상술하면 다음과 같다.The effect of the present invention as described above is as follows.

종래의 압출방법에 의하여 전선 또는 전열선(1)을 피복할 수 없던 것을 TFE로 만든 테이프(2)를 나선상으로 피복 융점이상의 온도 550-650℃로 유지되는 파이프관(3)내를 통과시키므로서 용이하게 피복되어 생산성이 향상되고 피복상태가 균일하고 제품이 미려하여 내열, 내약품성 및 내절연성을 갖는 전열선을 제공하게 된다.It is easy to pass the inside of the pipe 3, which is held at a temperature of 550-650 ° C. above the melting point of the tape 2 made of TFE, by which the wire or heating wire 1 cannot be covered by the conventional extrusion method. It is coated so that the productivity is improved, the coating state is uniform and the product is beautiful to provide a heating wire having heat resistance, chemical resistance and insulation resistance.

본 발명을 실시예에 따라 상술하면 다음과 같다.Hereinafter, the present invention will be described in detail as follows.

[실시예]EXAMPLE

제1도와 같이, 피복되지 않은 전선 또는 전열선(1)을 적당한 장력을 유지하고 일정속도로 이동전진시키면서 TFE 테이프(2)로 나선상으로 감는다. 이때 TFE 테이프(2)로 전선(1) 주위를 회전시키면서 감게 되므로 적당한 장력을 주면 전선(1)에 잘 밀착되면서 감겨지고 피복되는 두께는 TFE 테이프(2)의 두께로 조절하거나 또는 감는 회수에 따라 1회 또는 2회이상 중첩해서 감으므로 조절할 수 있다.As shown in FIG. 1, the uncoated wire or the heating wire 1 is spirally wound with the TFE tape 2 while moving at a constant speed while maintaining an appropriate tension. At this time, the TFE tape (2) is wound while rotating around the wire (1), if given the appropriate tension, the thickness of the wound and coated while being closely adhered to the wire (1) according to the thickness of the TFE tape (2) or depending on the number of times of winding It can be adjusted by winding one or more times.

또, 제2도와 같이, TFE 테이프(2)로서 나선상으로 권취 피복된 전선(1)을 550-650℃로 유지되는 철제 파이프관(3)내를 5-7m/sec의 속도로 통과시켜 냉각하면 본 발명이 완성된다.In addition, as shown in FIG. 2, when the wire 1 wound in a spiral shape as a TFE tape 2 is passed through the inside of the steel pipe tube 3 maintained at 550-650 ° C. at a rate of 5-7 m / sec, the cooling is performed. The present invention is completed.
