본 발명은 단열파이프에 관한 것으로서, 보다 상세하게는 단열성 뿐만 아니라 내열성이 향상된 새로운 구조의 단열파이프에 관한 것이다.The present invention relates to a heat insulation pipe, and more particularly to a heat insulation pipe of a new structure with improved heat resistance as well as heat insulation.

냉동장치, 냉난방장치와 같은 냉난방공조기기 등의 냉매관에는 단열파이프가 씌워진다. 이러한 단열파이프는 단열성이 우수한 소재로 이루어지는데, 고열이 발생되는 냉매관에는 단열성뿐만 아니라 내열성도 요구된다.Insulating pipes such as refrigeration and air conditioning equipment such as air conditioning and heating are covered with a heat insulating pipe. Such a heat insulating pipe is made of a material having excellent heat insulating properties, and a coolant tube in which high heat is generated requires not only heat insulating but also heat resistance.

한편, 고열이 발생되는 냉매관에는 내열성이 우수한 석면으로 된 단열파이프가 주로 사용된다. 그러나 석면은 고가일 뿐만 아니라 특정폐기물로 분류되기 때문에 폐기처리시에도 고비용이 소요된다. 또한, 석면은 작업고정에서 분진이 발생되어 작업환경이 오염되며, 이는 작업성을 저하시키는 원인이 된다. On the other hand, a heat insulating pipe made of asbestos, which is excellent in heat resistance, is mainly used for a refrigerant pipe in which high heat is generated. However, asbestos is not only expensive, but also classified as specific waste, which requires high costs for disposal. In addition, asbestos generates dust at work fixation and contaminates the work environment, which causes deterioration of workability.

한편, 단열파이프로 스티로폼이 사용되기도 하는데, 스티로폼 중량이 가볍고 가격도 저가인 장점이 있으나, 내열성이 좋지 않아 상기와 같이 고열이 발생되는 냉매관에는 사용이 곤란한 단점이 있다. On the other hand, styrofoam is also used as an insulation pipe, but the styrofoam has a light weight and a low price, but there is a disadvantage in that it is difficult to use a refrigerant tube that generates high heat as described above due to poor heat resistance.

본 발명은 상기의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 단열성이 우수할 뿐만 아니라 내열성이 향상되어 고열이 발생되는 배관에도 적용이 가 능한 새로운 구조의 단열파이프를 제공하는 것이다.The present invention is to solve the above problems, an object of the present invention is to provide a heat insulation pipe of a new structure that can be applied to the piping not only excellent heat insulation but also heat resistance is generated high heat.

According to another feature of the invention, the flame retardant injection process is to spray the flame retardant (12) at high pressure on the surface of the pipe 10 or the flame retardant (12) inside the pipe 10 through the nozzle 22 There is provided a method for manufacturing the heat insulation pipe 10, characterized in that the injection.

이하, 본 발명의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다. 도 1은 본 발명의 일 실시예를 보인 사시도이다. 본 발명은 내부에 난연 제(12)가 함유된 스티로폼 파이프(10)로 이루어진다. Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. 1 is a perspective view showing an embodiment of the present invention. The present invention consists of a styrofoam pipe (10) containing a flame retardant (12) therein.

이러한 본 발명은 다음과 같이 제작된다. 먼저 폴리스티렌수지를 압출발포하여 스티로폼 파이프(10)를 성형한다. 그리고 상기 파이프(10)의 내부에 난연제(12)를 주입한다. This invention is manufactured as follows. First, the polystyrene resin is extruded and molded to form the styrofoam pipe 10. And the flame retardant 12 is injected into the pipe 10.

난연제를 주입하는 과정은 도 1에 도시된 바와 같은 공급장치에 의해 이루어지는데, 이 공급장치는 외주면에 노즐(22)이 다수열로 배열형성된 주입롤러(20)와, 난연제저장탱크(30)와 연결되어 주입롤러(20)에 난연제(12)를 공급하는 공급관(40) 및 상기 주입롤러(20)를 회전시키는 모터(50)와, 상기 공급관(40)을 통해 난연제(12)가 공급되는 것 및 주입롤러(20)의 회전 등을 제어하는 제어부(60) 등으로 이루어진다. 그리고 상기 주입롤러(20)의 내부에는 노즐(22)의 열별로 연통되는 난연제유입통로(24)가 형성되어, 상기 공급관이 연결되는 난연제유입통로(24)와 연통되는 노즐(22)에만 선택적으로 난연제(12)가 분출되도록 구성되는데, 후술하는 바와 같이, 파이프(10)에 침투되는 열의 노즐(22)에만 난연제(12)가 분출되도록 구성된다. The process of injecting the flame retardant is carried out by a supply device as shown in FIG. 1, which comprises an injection roller 20 having a plurality of nozzles 22 arranged on the outer circumferential surface thereof, a flame retardant storage tank 30, Connected to the supply roller 40 to supply the flame retardant 12 to the injection roller 20 and the motor 50 to rotate the injection roller 20, the flame retardant 12 is supplied through the supply pipe 40 And a controller 60 for controlling the rotation of the injection roller 20 and the like. In addition, a flame retardant inlet passage 24 is formed in the injection roller 20 to communicate with each other by the rows of the nozzles 22, and selectively only the nozzle 22 in communication with the flame retardant inlet passage 24 to which the supply pipe is connected. The flame retardant 12 is configured to be ejected, but as described below, the flame retardant 12 is configured to be ejected only to the nozzles 22 of the heat penetrating the pipe 10.

한편, 성형된 스티로폼 파이프(10)는 주입롤러(20)와 근접되도록 이송된 후 제자리에서 회전되는데, 주입롤러(20)는 모터(50)에 의해 파이프(10)의 회전속도에 맞추어 파이프(10)의 회전방향과 반대되는 방향으로 회전된다. 이와 같이 주입롤러(20)와 파이프(10)가 근접되게 배치되어 회전됨에 따라 회전롤러(20)의 노즐(22)은 각 열별로 파이프(10)에 침투 및 이탈된다. 그리고 주입롤러(20)의 노즐(22)이 파이프(10)에 침투되면 노즐(22)을 통해 파이프(10)의 조직 내부로 난연제(12)가 분 사되어, 파이프(10), 즉, 스티로폼의 조직 내부에 난연제(12)가 침투된다. 물론 스티로폼의 밀도에 따라 다소 차이가 있을 수 있겠으나, 실험에 의하면, 상기 노즐(22)을 통한 난연제(12)의 분사압력이 0.5 ~ 5㎏/㎠ 정도일 때 난연제(12)가 스티로폼이 깨지지 않으면서 스티로폼의 조직 내부로 난연제(12)가 효과적으로 침투된다. On the other hand, the molded styrofoam pipe 10 is rotated in place after being transported close to the injection roller 20, the injection roller 20 by the motor 50 to match the rotational speed of the pipe 10 pipe (10) Rotate in the direction opposite to the direction of rotation. As the injection roller 20 and the pipe 10 are disposed close to each other and rotated as described above, the nozzles 22 of the rotary roller 20 penetrate into the pipe 10 for each row and are separated from each other. When the nozzle 22 of the injection roller 20 penetrates the pipe 10, the flame retardant 12 is sprayed into the tissue of the pipe 10 through the nozzle 22, so that the pipe 10, that is, styrofoam Flame retardant 12 is penetrated into the tissue of the. Of course, there may be a difference depending on the density of the styrofoam, but according to the experiment, when the injection pressure of the flame retardant 12 through the nozzle 22 is about 0.5 ~ 5kg / ㎠ the styrofoam does not break the styrofoam Flame retardant 12 is effectively penetrated into the tissue of the styrofoam.

이와 같이 파이프(10), 즉, 스티로폼에 난연제(12)를 주입한 다음에는 난연제(12)를 건조시킨다. 상기 난연제(12)로는 물유리, 탄산수소나트륨, 수산화마그네슘, 수산화알루미늄 등이 사용된다. As such, after the flame retardant 12 is injected into the pipe 10, that is, the styrofoam, the flame retardant 12 is dried. As the flame retardant 12, water glass, sodium hydrogen carbonate, magnesium hydroxide, aluminum hydroxide and the like are used.

이상과 같이 제조된 본 발명에 의한 단열파이프는 스티로폼의 장점, 즉, 저가이면서도 단열성이 우수하고, 중량이 적은(즉, 가벼운) 장점을 그대로 유지하면서, 내부에 함유된 난연제(12)에 의해 내열성이 향상되며 더불어 난연성도 향상된다. 따라서 본 발명에 의한 단열파이프는 고열이 발생되는 배관(2)에도 적용이 가능하다. The heat insulation pipe according to the present invention manufactured as described above is heat resistant by the flame retardant 12 contained therein while maintaining the advantages of styrofoam, that is, low cost and excellent heat insulation, and low weight (that is, light). This improves and also improves flame retardancy. Therefore, the heat insulation pipe according to the present invention can be applied to the piping 2 in which high heat is generated.

이상에서는 스티로폼 파이프(10)에 노즐(22)을 꽂아서 난연제(12)를 주입하는 것을 예로 들어 설명하였으나, 경우에 따라서는 액상의 난연제(12)를 스티로폼 파이프(10)의 외주면 또는 내주면에 고압으로 분사하여 파이프(10) 조직 내부에 난연제(12)가 침투되도록 할 수도 있다. In the above description, for example, the flame retardant 12 is injected into the styrofoam pipe 10 by inserting the nozzle 22 into the styrofoam pipe 10. The flame retardant 12 may be penetrated into the pipe 10 tissue by spraying.

이상에서와 같이 본 발명에 의하면, 단열성이 우수하고 가벼운 스티로폼의 장점을 유지하면서 이에 더하여 내열성이 향상되어 고열이 발생되는 배관에도 적용이 가능한 단열파이프가 제공된다. 또한, 내열성 뿐만 아니라 난연성도 향상되므로 화재시 파이프가 불에 타면서 유독가스가 배출되는 것도 감소된다. 따라서 본 발명에 의한 단열파이프는 종래 석면파이프 대용으로 사용이 가능하므로 석면파이프의 사용량을 줄일 수 있고, 이에 따라 석면 사용에 따른 환경오염도 줄일 수 있다. According to the present invention as described above, while maintaining the advantages of excellent styrofoam with excellent heat insulation, in addition to the heat resistance is improved is provided an insulating pipe that can be applied to the piping generates high heat. In addition, the heat resistance as well as the flame retardancy is improved to reduce the emission of toxic gas as the pipe burns in the fire in case of fire. Therefore, since the insulating pipe according to the present invention can be used as a substitute for conventional asbestos pipe, it is possible to reduce the amount of asbestos pipe used, thereby reducing environmental pollution caused by the use of asbestos.
