Abstract: 본 발명은 하수관이나 배수관으로 사용되는 스파이널 파이프에 관한 것으로 더욱 상세하게는 폐플라스틱이나 폐필름 등을 이용한 재료를 사용하여 압출성형기에서 내부가 체워지는 사각형의 프로파일을 성형하고 양측에서 보조압출기를 이용하여 수지를 공급하여 프로파일을 접합시키는 과정을 통하여 성형되는 폐플라스틱을 이용한 스파이널 파이프 및 그 성형장치에 관한 것이다. 
     종래의 스파이널 파이프는 내부가 중공형인 I빔 형으로 성형시 냉각과정후 접착수지를 공급하여 접착하므로 일체형의 접착이 이루어 지지 않아서 외압에 의하여 쉽게 분리되거나 파단되는 것이며, 100%의 폴리에틸렌즈로 되어 있어서 가격이 고가 이었다. 
     따라서 본 발명은 190 ∼ 230℃의 융점에서 폐플라스틱을 용융시켜 압출성형기(3)와 보조압출기(4)(5)로 공급하되 압출성형기(3)에서는 사각형의 프로파일(9)을 성형하며, 프로파일(9)의 양측에서 보조압출기(4)(5)로 공급되는 수지에 의하여 와인더(6)의 외측에서 프로파일(9)과 단일체의 접합수지층(12)을 이루도록 하여 스파이널 파이프(2)를 성형하는 성형장치와, 용융되지 않은 내층(10)과 용융된 외층(11)프로파일(9)의 사면을 감싸는 접합수지층(12)이 H빔 형태를 이루도록 하여 외압에 견고하여 파손되지 않고 폐플라스틱을 이용하여 자원을 재활용하므로 환경오염을 방지할 수 있으며, 또한 왕겨, 벼짚 등 농작물 부산물 등을 배합하여 사용할 수 있으므로 회기적으로 원가를 절감할 수 있는 것이다.
