Description

열수축 튜브의 제조방법Manufacturing method of heat shrink tube

본 발명은 열수축 튜브의 제조방법에 관한 것으로, 더욱 상세하게는 일반적인 팽창공정이 필요없이 제조할 수 있는 섬유보강형 다층 열수축 튜브의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a heat shrink tube, and more particularly to a method of manufacturing a fiber-reinforced multilayer heat shrink tube that can be produced without the need for a general expansion process.

일반적으로 열수축 튜브는 먼저 열가소성 수지를 압출한 다음 가교시키고 다시 수지의 결정 용융온도 이상의 온도로 가열한 후 팽창하여 냉각하는 방법을 사용하여 제조하는데 이렇게 만든 열수축 튜브는 전선 연결부의 피복등 다양한 분야에서 다양한 용도로 사용되고 있다.In general, heat shrink tubes are manufactured by first extruding thermoplastic resin, crosslinking, heating to a temperature higher than the crystal melting temperature of the resin, and then expanding and cooling the heat shrink tubes. It is used for a purpose.

도 1은 종래의 일반적인 열수축 튜브를 나타내는 개략도이다. 섬유 보강형 열수축 튜브(1)는 먼저 1차 내부 튜브(3)를 압출하고 수축성이 없는 보강재(4)를 감은 후 그 위에 2차 외부 튜브(7)를 압출한다. 상기 2차 외부 튜브(7)를 압출한 후 가교공정을 거친 다음 가교된 원튜브를 다시 가열하여 팽창하는 방법으로 제조하였다.1 is a schematic view showing a conventional general heat shrink tube. The fiber reinforced heat shrink tube 1 first extrudes the primary inner tube 3, winds up the non-shrinkable reinforcement 4, and then extrudes the secondary outer tube 7 thereon. After extruding the secondary outer tube (7), the crosslinking process was performed, and then the crosslinked raw tube was heated and expanded.

전술한 종래의 일반적인 열수축 튜브는 고가의 팽창설비가 필요하고 팽창작업시 보강용으로 사용된 섬유의 재질과 튜브에 사용된 재료의 재질이 달라 팽창에 적합한 온도조건의 설정이 어려우며 완성튜브의 수축작업시에도 보강용 섬유가 튜브의 수축을 방해하는 경우가 많아 사용이 불편한 문제점이 있었다.The above-described conventional heat shrink tube requires expensive expansion equipment, and the material of the fiber used for reinforcement and the material used for the tube is different because it is difficult to set a suitable temperature condition for expansion and shrinkage of the finished tube. Even when the reinforcing fibers often interfere with the shrinkage of the tube, there was a problem inconvenient to use.

본 발명은 전술한 문제점을 감안하여 안출한 것으로서, 본 발명의 목적은, 튜브를 팽창하여 수축성을 주는대신 미리 가교 및 연신하여 만든 수축성 섬유를 튜브에 감아 수축력을 주기 때문에 팽창공정이 필요없으며 특히 수축시에도 보강용 섬유자체가 수축하기 때문에 수축 방해요인이 없어지므로 쉽게 사용할 수 있는 열수축 튜브의 제조방법을 제공하는데 그 목적이 있다.The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a shrinkage force by winding the shrinkable fibers made by crosslinking and stretching in advance instead of expanding the tube to give shrinkage, and thus, the expansion process is not necessary, and in particular, shrinkage. It is an object of the present invention to provide a method of manufacturing a heat shrinkable tube that can be easily used since the reinforcing fiber itself shrinks even when shrinkage is prevented.

전술한 목적을 달성하기 위하여, 본 발명은, 열수축 튜브(1)를 이루는 1차 내부튜브(3), 보강재(4) 및 2차 외부튜브(7)를 포함하는 열수축 튜브의 제조방법에 있어서, 상기 1차 내부튜브(3)는 외부로 미리 가교 및 연신하여 수축성을 가지는 열수축성 보강섬유(5)를 감고 상기 1차 내부튜브(3)의 내부에 공기를 주입하여 외형을 유지하면서 2차 외부튜브(7)를 압출하고 튜브 형태를 유지하면서 냉각하여 제조하는 것을 특징으로 하는 열수축 튜브의 제조방법을 제공한다.In order to achieve the above object, the present invention, in the method for producing a heat shrink tube comprising a primary inner tube (3), a reinforcing material (4) and a secondary outer tube (7) forming a heat shrink tube (1), The primary inner tube 3 is pre-crosslinked and stretched to the outside to wrap the heat shrinkable reinforcing fiber 5 having shrinkage and inject air into the inner inner tube 3 to maintain the appearance while maintaining the outer appearance. It provides a method for producing a heat shrinkable tube, characterized in that the tube 7 is produced by extruding and cooling while maintaining the shape of the tube.

이하, 첨부도면을 참조하여 본 발명의 바람직한 일실시예를 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings illustrating a preferred embodiment of the present invention.

도 2는 본 발명의 일실시예에 의한 열수축 튜브를 나타내는 단면도로서, 열수축 튜브(1)는 제조공정시 먼저 열가소성 수지로 구성된 1차 내부튜브(3)를 압출하여 냉각시키고 상기 1차 내부튜브(3)의 위에 미리 준비해 둔 열수축성 보강섬유(5)를 감는다. 상기와 같은 1차 내부튜브(3)의 내부에 공기를 주입하여 외형을 유지하면서 그 위에 2차 외부튜브(7)를 압출하고 튜브 형태를 유지하면서 냉각하여 제조한다.Figure 2 is a cross-sectional view showing a heat shrink tube according to an embodiment of the present invention, the heat shrink tube (1) in the manufacturing process first by extruding and cooling the primary inner tube (3) made of a thermoplastic resin and the primary inner tube ( 3) Wind the heat shrinkable reinforcing fibers (5) prepared in advance. It is prepared by injecting air into the inside of the primary inner tube 3 as described above while extruding the secondary outer tube 7 thereon while maintaining the appearance and cooling while maintaining the form of the tube.

도 3은 본 발명의 일실시예에 의한 열수축 튜브의 제조 공정도로서, 1차 내부튜브(3)는 양쪽으로 접착제 도포장치(9)를 형성하고 상기 1차 내부튜브(3)의 외측의 축방향으로 약 25-80도 정도의 각도를 유지하면서 열수축성 보강섬유(5)를 감는다.3 is a manufacturing process diagram of a heat shrinkable tube according to an embodiment of the present invention, in which the primary inner tube 3 forms an adhesive coating device 9 on both sides and an axial direction of the outer side of the primary inner tube 3. The heat shrinkable reinforcing fiber (5) is wound while maintaining an angle of about 25-80 degrees.

또한, 상기 1차 내부튜브(3)의 일단으로 압출기(11)를 형성하며 상기 압출기(11)가 지나간 자리로는 완성된 열수축튜브(13)가 형성된다.In addition, an extruder 11 is formed at one end of the primary inner tube 3, and a completed heat shrink tube 13 is formed at a place where the extruder 11 has passed.

전술한 구성에 대한 작용을 설명하면, 열가소성 수지를 튜브로 한 1차 내부튜브(3)를 압출하여 냉각한 후 준비된 열수축성 보강섬유(5)를 상기 1차 내부튜브(3)위로 감는다. 상기 열수축성 보강섬유(5)는 도 2 및 도 3에 도시한 바와 같이 축방향으로 약 25-80도 정도의 각도를 유지하게 감는데 각이 너무 작으면 길이 방향으로 줄어들 수 있기 때문에 일반적으로 60-70도가 적당하다.Referring to the operation of the above-described configuration, after extruding and cooling the primary inner tube 3 made of a thermoplastic resin tube, the prepared heat shrinkable reinforcing fiber 5 is wound on the primary inner tube 3. The heat-shrinkable reinforcing fiber 5 is wound to maintain an angle of about 25-80 degrees in the axial direction as shown in FIGS. 2 and 3, but if the angle is too small, it is generally reduced in the longitudinal direction. -70 degrees is suitable.

또한, 상기 열수축성 보강섬유(5)는 1차 내부튜브(3)의 전체 면적의 약 25-50%를 차지할 만큼 감게 되는데 이는 상기 열수축성 보강섬유(5)의 수축성을 가장좋게 것이다.In addition, the heat-shrinkable reinforcing fibers (5) is wound to occupy about 25-50% of the total area of the primary inner tube (3), which is the best shrinkage of the heat-shrinkable reinforcing fibers (5).

상기 열수축성 보강섬유(5)가 감겨있는 1차 내부튜브(3)에는 공기를 불어 넣어 상기 1차 내부튜브(3)의 원형을 유지함과 동시에 열수축성 보강섬유(5)의 수축을 방지하면서 2차 외부튜브(7)를 압출하고 냉각하여 완성된 열수축 튜브(1)를 형성한다.While maintaining the circular shape of the primary inner tube (3) by blowing air to the primary inner tube (3) wound around the heat shrinkable reinforcing fiber (5) while preventing the shrinkage of the heat shrinkable reinforcing fiber (5) 2 The primary outer tube 7 is extruded and cooled to form a finished heat shrinkable tube 1.

전술한 구성과 작용에 의해 나타나는 본 발명의 효과를 알아 보면, 상기와 같은 방법으로 제조한 열수축 튜브는 찢어짐에 대한 저항성을 가짐은 물론 수축성 섬유에서 수축력을 얻게 되므로 팽창공정이 필요없어 팽창설비에 대한 투자가 필요없고 팽창공정에서 발생되는 제반 문제들의 해결이 가능하며 수축시에도 보강재가 수축에 방해가 되지 않는 효과가 있다.Looking at the effects of the present invention exhibited by the above-described configuration and action, the heat shrink tube manufactured by the above method has a resistance to tearing, as well as the contraction force is obtained from the shrinkable fibers, so that the expansion process is not necessary. There is no need for investment, it is possible to solve all the problems caused in the expansion process, and the reinforcement does not interfere with the contraction even when shrinking.

또한, 팽창공정이 삭제되므로 공정이 단축되어 길이방향 수축율을 줄일수 있으며 가교공정도 생략할 수 있거나 간단하게 가교공정을 끝낼수 있는 효과가 있다.In addition, since the expansion process is eliminated, the process can be shortened to reduce the longitudinal shrinkage rate, and the crosslinking process can be omitted or the crosslinking process can be simply completed.
