Description
본 발명 주로 농촌이나 각종 산업 현장에서 버려지는 폴리에틸렌 재생수지를 이용하여 삼층으로 원형 압출하여 제조하는 배수관에 관한 것으로서,The present invention relates to a drain pipe manufactured by circular extrusion into three layers using polyethylene recycled resin mainly discarded in rural or various industrial sites,
현재 하수, 우수 등 배수관으로 널리 사용되고 있는 것은 주철관, 콩크리트흄관, PVC관, 폴리에틸렌관 등이 있으나, 주철관이나 콩크리트흄관은 장기 사용 시 하수에 침식되어 쉽게 부식이 일어나고 있다, 그리고 PVC관은 부식이 일어나지 않는 대신 쉽게 파손되는 단점을 가지고 있다. 그 중에서도 쉽게 파손되지 않고 부식이 일어나지 않는 폴리에틸렌 배수관을 널리 사용되고 있는 실정이나, 제조과정에서 프로파일(profile)을 압출해서 와인더(winder) 공정에서 융착(접착)에 의한 공법으로 폴리에틸렌 배수관을 생산하고 있으므로, 생산성이 저하되어 제조원가가 상승하며, 융착 부위의 파손으로 배수관이 파손될 우려가 있었다. 파이프가 균열될 수 있는 요소를 완전히 제거함과 동시에 생산단가도 절감할 수 있는 기술의 발명이 절실히 요구되고 있는 실정이다.Currently, there are cast iron pipes, concrete fume pipes, PVC pipes, polyethylene pipes, etc., which are widely used for drainage pipes such as sewage and rainwater, but cast iron pipes or concrete fume pipes are easily eroded by sewage after long-term use. Instead, it has the disadvantage of being easily broken. Among them, polyethylene drain pipes which are not easily damaged and do not cause corrosion are widely used.However, since the profile is extruded during the manufacturing process, the polyethylene drain pipe is produced by a fusion method in the winder process. In addition, productivity decreased and manufacturing cost increased, and there was a fear that the drainage pipe was damaged due to breakage of the fusion site. The present invention is urgently required to invent a technology that can completely eliminate the elements that can crack the pipe and at the same time reduce the production cost.
본 발명은 이러한 문제점을 해결하기 위해 새로운 생산방법을 적용하여 구조적 결함을 해소하고 생산단가를 대폭 낮추어 경제적 효율성이 높은 재생 폴리에틸렌 수지를 이용한 삼층배수관 및 그 생산방법에 관한 것으로서,The present invention relates to a three-layer drainage pipe using a recycled polyethylene resin and a method for producing the same by applying a new production method to solve structural problems and significantly reduce production costs to solve such problems.
일단 본체를 압출하고 그 내면에는 하수 및 오수가 직접 닿는 부위이므로 내구성을 위하여 폴리에틸렌 신소재를 이용하여 내면을 압출하여 구성하며 외면에는 관층별 쉽게 구분을 위해 (예: 우수관 : 회색, 하수관: 암갈색) 표면을 얇게 폴리에틸렌 신소재로 압출피복한다.Extrude the body and its inner surface is directly contacted with sewage and sewage, so it is constructed by extruding the inner surface using a new polyethylene material for durability, and the outer surface is easily distinguished by each pipe layer (e.g. storm pipe: gray, sewer pipe: dark brown) Thinly extruded with polyethylene new material.
이렇게 생산된 폴리에틸렌 삼중층 배수관은, 기존의 폴리에틸렌 이중 벽관에 비해, 직선도가 우수하며 강도 및 내구성이 우수하며 동시에 국가적 현안과제인 폐기물인 폴리에틸렌 재생수지를 이용하므로 환경문제도 해결하고 경제적으로도 효율적인 삼층 폴리에틸렌 배수관을 제공함을 본 발명의 기술적 과제를 두고 창안하였다.The polyethylene triple layer drain pipe produced in this way has superior linearity, superior strength and durability, and at the same time uses polyethylene recycled resin, which is a national challenge, solves environmental problems and is economically efficient. Providing a three-layer polyethylene drain pipe was made with the technical problem of the present invention.

일반적으로 도시나 산업현장에서 수거되는 폴리에틸렌 재생수지는 종류별 (저밀도, 중밀도, 고밀도) 색상별로 구분이 힘들다. 또한 생산된 프로파일을 융착하여 본체를 만들기 때문에 연결부에 손상이 발생할 우려가 있었다. 이에 본 발명은 도 2,3에 도시된 바와 같이 폐비닐등 혼합되어 있는 폴리에틸렌 수지를 상용화제를 이용하여 폴리에틸렌 재생수지를 제조하고, 상기 재생수지를 압출기를 이용하여 중간층(2)을 형성하고 폴리에틸렌 신소재를 이용하여 내면층(1) 및 외면층(3)을 피복 압출하는 것으로, 기존의 재생된 폴리에틸렌 프로파일을 와인더를 통하여 권취, 접착하여 본체 즉 중간층을 생산방법 대신에,Generally, polyethylene recycled resins collected in urban or industrial sites are difficult to distinguish by color (low density, medium density, high density). In addition, there is a risk of damage to the connection part because the body produced by fusion of the produced profile. Thus, the present invention is to produce polyethylene recycled resin by using a compatibilizer for polyethylene resin mixed with waste vinyl, as shown in Figures 2 and 3, and to form the intermediate layer (2) by using an extruder By coating and extruding the inner layer (1) and outer layer (3) using a new material, the existing regenerated polyethylene profile is wound and bonded through a winder, instead of producing a main body, that is, an intermediate layer,
도4,5에 도시된 바와 같이 1차압출기를 통하여 중간층(2)을 압출하고,As shown in Figs. 4 and 5, the intermediate layer 2 is extruded through the primary extruder,
내면층(1)은 2차 압출기로 폴리에틸렌 신소재를 이용하여, 하수 및 오수가 직접 닿는 부분이므로 두껍게 압출하고,Inner layer (1) is a second extruder using a new polyethylene material, so that the sewage and sewage directly contact parts, and extruded thickly,
외면층은(3)은 쉽게 관층별로 구분할 수 있도록 폴리에틸렌 신소재에 색상(암갈색, 흑색,회색)을 넣어 얇게 피복하며 압출한다.The outer layer (3) is extruded with a thin coating by putting a color (dark brown, black, gray) in a new polyethylene material so that it can be easily distinguished by tube layer.
따라서, 상기의 내면층(1) 중간층(2), 외면층(3)은 다이스 성형장치를 통하여 원형 압출시켜 일체화되어 진공냉각공정을 거쳐 형성된 폴리에틸렌 배수관을 수요자의 길이 (통상 규격상 - 6m) 에 맞게 절단하는 것이다. 물론 내외면층(1,3)을 동시에 압출시키는 압출기로 다이스 성형장치를 통하여 일체화된 삼중층 폴리에틸렌관을 원형 압출시킬 수도 있다.Accordingly, the inner surface layer 1, the intermediate layer 2, and the outer surface layer 3 are integrated by circular extrusion through a die forming apparatus, and the polyethylene drain pipe formed through the vacuum cooling process is used to the length of the consumer (normally-6 m). Cutting to fit. Of course, it is also possible to circularly extrude the integrated triple-layer polyethylene tube through the die forming apparatus with an extruder that simultaneously extrudes the inner and outer layers 1 and 3.
상기 살펴본 바와 같은 공정으로 아파트배란다에 설치되는 오수관이나 기타 주택과 건축물의 배수관으로 사용되는 재생 배수관을 생산할 경우 폐비닐에 일상적으로 함유된 흙을 제거하지 않고 재생수지로 제조할 수 있을 뿐만 아니라 단수 플라스틱으로 제조하여 시간이 경화함에 따라 노후되거나 자외선에 의하여 물성이 변화되어 쉽게 손상되는 단점과 오수 등이 흘러내리 때 와류하는 현상에 의한 소음의발생 및 생산 구조적으로 발생할 수 있는 중간층 결합을 방지하고, 별도의 와인더 공정없이 다이스를 통해 일체화 시켜 압출함으로 제조공정상의 편리함을 가지면서 우수한 성질을 가지는 재생배수관을 구성할 수 있게 되는 것이다.In the process as described above, when producing recycled drain pipes used as sewage pipes installed in the apartment porch or drain pipes of other houses and buildings, it is possible to manufacture recycled resins without removing soil contained in waste vinyl. It prevents the generation of noise due to the phenomenon of vortexing when the sewage flows down and the damage that is easily damaged due to aging or change of physical properties by ultraviolet rays as time is hardened, and prevents the interlayer bonding that may occur in production structure. It is possible to construct a regeneration drainage pipe having excellent properties while having convenience in the manufacturing process by integrating through a die without a winder process.
이상과 같은 본 발명 원형 압출식 삼층 폴리에틸렌 배수관 및 그 제조방법을 통하여, 무작위로 버려지는 폴리에틸렌 재생수지를 원료로 하여 배수관을 만듦으로 재생수지를 이용한 제품의 경제성을 높일 수 있으며, 폴리에틸렌관의 삼중층을 원형 압출방식으로 일체화 시켜 생산함으로 생산단가를 낮추고 보다 내구성이 뛰어나고 영구적으로 사용할 수 있는 폴리에틸렌 배수관을 제공이 가능하게 되어 다양한 효과를 얻을 수 있는 발명이라고 하겠다.Through the invention of the present invention as described above circular extruded three-layer polyethylene drain pipe and its manufacturing method, it is possible to improve the economics of the product using the recycled resin by making the drain pipe from the polyethylene recycled resin discarded randomly, the triple layer of polyethylene pipe It is an invention that can produce various effects by lowering the production cost and providing a polyethylene drain pipe that can be used more durable and permanently by producing the integrated by the extrusion extrusion method.
