본 발명은 폐폴리에틸렌필름을 재생하여 활용하는 방법 및 장치에 관한 것으로, 특히 수거한 폐폴리에틸렌을 결합제로 하여 압축강도가 높고 내약품성이 우수한 재료를 생산하여 기기의 기초대나 농수용 플륨 및 건축자재등을 제조함으로써 폐자원의 재활용 및 환경보존에 일조할 수 있는 폐폴리에틸렌을 이용한 폴리머콘크리트제품제조방법 및 그 제조장치에 관한 것이다.The present invention relates to a method and apparatus for recycling waste polyethylene film, and particularly, to produce a material having high compressive strength and excellent chemical resistance by using collected waste polyethylene as a binder, such as a foundation for farming equipment, farm water, and building materials. The present invention relates to a method for producing polymer concrete products using waste polyethylene and an apparatus for manufacturing the same, which can contribute to recycling of waste resources and environmental conservation.

보편적으로, 화학공업의 발달에 따라 인류의 일상생활에 없어서는 아니될 필수품이 된 합성수지제품인 비닐은, 많은 장점에도 불구하고 소각시 유독물질의 발생, 자연상태에서의 난분해성 때문에 그 폐기물의 처리가 큰 사회문제로 대두되고 있다. 특히, 비닐중 폴리에틸렌(Polyethylene)은 내수성, 내약품성, 전기절연성이 우수하며 무독성이어서 많은 분야에서 사용되고 있으나, 이를 수거하여 페기처리하는 데에는 많은 기술적인 문제와 제비용등의 문제 및 환경오염등의 난제(難題)가 산적되어 있다. 일예로 이러한 폴리에틸렌필름은 농사용으로 널리 사용되고 있으며, 최근에는 이들 필름을 사용후 폐기 처분하는데 많은 어려움을 겪고 있는 실정이다.In general, vinyl, a synthetic resin product, which has become an indispensable necessity in the daily life of mankind due to the development of the chemical industry, has a great deal of waste due to the generation of toxic substances during incineration and difficult degradability in the natural state. It is a social problem. Particularly, polyethylene in vinyl has excellent water resistance, chemical resistance, electrical insulation and non-toxicity and is used in many fields.However, there are many technical problems, costs, and environmental problems such as waste disposal and waste disposal. Viii) is stacked. For example, these polyethylene films are widely used for farming, and in recent years, they are having a lot of difficulties in discarding these films after use.

따라서, 폐 비닐의 재생 내지 재활용 문제는 단순한 에너지 절약의 차원을 넘어 폐기물 처리의 가장 이상적인 방안으로서 최근 선진 각국의 주요 관심사가 되고 있다.Therefore, the problem of recycling or recycling waste vinyl goes beyond simple energy saving and has become a major concern of developed countries as an ideal solution for waste disposal.

폐비닐의 재생이용기술은 크게 용융재생법과 용해재생법으로 구분할 수 있다. 용융재생법은 폐비닐을 가열하여 용융상태로 하고 형에 넣어 일정한 형태로 냉각시키는 방법이며, 용해재생법은 용매를 사용하여 폐비닐을 용해하는 방법이다. 이때, 폴리에틸렌은 80∼100℃에서 용매인 파라핀계 탄화수소에 15% 정도 용해되거나, 용매인 광유(mineral oil)에서 3.5% 정도 용해된다. 하지만, 이들 용매를 사용할 경우 그 처리비가 상승하게 된다.Recycling technology of waste vinyl can be divided into melt regeneration method and melt regeneration method. Melt regeneration is a method in which waste vinyl is heated to a molten state, put into a mold, and cooled in a constant form. Dissolution regeneration is a method of dissolving waste vinyl using a solvent. At this time, the polyethylene is dissolved in about 15% in a paraffinic hydrocarbon as a solvent at 80 ~ 100 ℃, or about 3.5% in mineral oil (mineral oil) as a solvent. However, the use of these solvents increases the treatment cost.

절단기(10)에서 일정길이로 절단된 폐폴리에틸렌필름은 벨트컨베이어(11)에 의해 이송되어 트윈익스트루더(20)로 공급된다. 이 트윈익스트루더(20)에서는 폐폴리에틸렌필름이 1차 용융압축되어 싱글익스트루더(30)로 공급되어 2차용융압축과정을 거치게 된다. 이때, 1,2차용융압축은 200∼220℃에서 진행된다. 이와 같이 용융된 액상의 폐폴리에틸렌은 혼합기(40)에 투입되어 부재료저장탱크(50)에서 스크류컨베이어(51)에 의해 공급된 모래와 일정비율로 균질하게 혼합되게 된다. 이때, 모래는 유기결합제인 액상의 폐폴리에틸렌에 의해 결합된다. 혼합된 혼합재료는 버킷컨베이어(60)로 공급기(70)에 공급되어 사출성형기(80)를 거쳐 평판으로 사출성형된다. 이 평판은 가열기(90)에 의해 일정온도로 가열되어 프레스(100)로 들어가 금형에 의해 가압되어 소정형상으로 성형되어 나온다. 이렇게 성형된 제품은 냉각기(110)를 거치면서 냉각되어 순환컨베이어(130) 및 롤컨베이어(120)를 통해 적치장(積置場)에 적치된다.The waste polyethylene film cut to a predetermined length in the cutter 10 is transferred by the belt conveyor 11 and supplied to the twin extruder 20. In the twin extruder 20, the waste polyethylene film is first melt compressed and supplied to the single extruder 30 to undergo a second melt compression process. At this time, the first and second melt compression is carried out at 200 ~ 220 ℃. The molten liquid waste polyethylene is introduced into the mixer 40 to be homogeneously mixed with the sand supplied by the screw conveyor 51 in the subsidiary material storage tank 50 at a constant ratio. At this time, the sand is bonded by liquid waste polyethylene which is an organic binder. The mixed material is supplied to the feeder 70 by the bucket conveyor 60 and injection molded into the plate via the injection molding machine 80. The plate is heated to a constant temperature by the heater 90, enters the press 100, is pressed by a mold, and is molded into a predetermined shape. The molded product is cooled while passing through the cooler 110, and is deposited in the stockyard through the circulation conveyor 130 and the roll conveyor 120.

이상 설명한 바와 같이, 본 발명은 열가소성수지인 폴리에틸렌을 결합제로 이용하므로 압축강도, 내화성, 내약품성등의 성능이 우수한 기기기초대 및 보도블럭등의 자재를 제작할 수 있는 잇점이 있다. 본 발명은 또한 농업용 멀칭이나 비닐하우스재료로 사용하다가 폐기되는 폐폴리에틸렌필름을 수집하여 결합제로 사용하므로 자원재활용이라는 측면에서 기대되는 파급효과가 매우 크며, 특히 환경적인 측면에서 국가적으로 장려될 것으로 전망된다. 더욱이, 일반적으로 재생이 용이한 고압법 생산방법에 의한 저밀도 폴리에틸렌필름을 재료로 하지 않고, 재생이 비교적 용이하지 않아 폐기가 불가피한 저압법 생산방법에 의한 고밀도 폴리에틸렌필름을 주원료로 하므로 더욱 그 가치가 크다.As described above, the present invention uses polyethylene, which is a thermoplastic resin, as a binder, and thus has advantages in producing materials such as machine bases and sidewalk blocks having excellent performances such as compressive strength, fire resistance, and chemical resistance. The present invention also collects waste polyethylene film used as agricultural mulching or vinyl house material, and uses it as a binder, so the ripple effect is expected to be very high in terms of resource recycling, and in particular, it is expected to be promoted nationally in terms of environment. . Moreover, it is more valuable because it is made of low-density polyethylene film by the high pressure production method, which is easy to recycle in general, and high density polyethylene film by the low pressure production method, which is inevitable to be discarded because it is relatively easy to recycle. .
