The present invention relates to a method of regenerating waste styrofoam, which can prevent the occurrence of waste, minimize the manpower, cost and time required for incineration, and obtain the effect of resource saving by recycling the resources.
가전제품이나 각종 전자제품을 생산하여 판매시 제품을 보호하기 위하여 사용되어지는 스치로폼은 구매자가 제품을 구입한 후 대부분 버려지고 있다.Styrofoam, which is used to produce home appliances or various electronic products and protect them during the sale, is mostly discarded after the purchaser purchases the product.
따라서 폐 스치로폼에 의한 환경오염이 날로 심각해지면서 이를 해결하기 위하여 폐 스치로폼을 별도의 집하창고에 수거하여 소각공장에서 소각시키는 방법이 사용되어지고 있다.Therefore, environmental pollution caused by waste styrofoam is becoming more serious and in order to solve this problem, a method of collecting waste styrofoam in a separate warehouse for incineration at an incineration plant has been used.
그러나 상기와 같이 폐 스치로폼을 수거하였다가 소각시키는 방법은 소각전 불순물을 제거하고 세척해야 하는 번거로움이 있고, 스치로폼을 소각공장으로 운반시 부산물 등이 떨어질 우려가 있으며, 소각작업에 많은 인려과 비용 및 시간이 소요되고, 별도의 집하창고가 필요함은 물론 소각시 발암물질과 같은 환경오염물질의 발생으로 환경을 오염시키게 되는 문제점이 있었다.However, the method of collecting and incineration of waste Styrofoam as described above has the trouble of removing and cleaning impurities before incineration, and there is a fear that by-products will fall when transporting Styrofoam to an incineration plant. And it takes time, there is a need for a separate warehouse, as well as the problem of polluting the environment by the generation of environmental pollutants such as carcinogens when incinerated.
본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 폐 스치로폼을 소각하지 않고 융해용제를 사용해 간단히 용해시켜 파레트로 재생시키므로서, 폐 스치로폼의 재활용에 따른 자원절약의 효과를 얻을 수 있슴은 물론, 별도의 집하창고와 불순물 제거작업, 세척작업이 필요없어 폐 스치로폼의 처리에 따른 인력과 비용 및 시간을 최소화 하고, 환경오염을 방지할 수 있는 폐 스치로폼의 재생방법을 제공함에 본 발명의 목적이 있다.The present invention has been made in order to solve the above problems, by simply dissolving the waste styrofoam using a melting solvent to regenerate the pallet, it is of course possible to obtain the effect of resource saving according to the recycling of waste styrofoam The object of the present invention is to provide a recycling method of waste styrofoam, which minimizes manpower, cost and time due to the disposal of waste styrofoam, and does not require a separate warehouse, removing impurities, and washing. have.
이하, 본 발명의 바람직한 실시예를 설명한다.Hereinafter, preferred embodiments of the present invention will be described.

상기에서 사용되는 융해 용제인 메틸렌 크로라이드는 CH2Cl2로 표기되는 클로로 카본계 물질로서 환경 및 인체에 큰 유해성이 없어 안전성이 높은 물질이다.Methylene chromide, a fusion solvent used above, is a chloro carbon-based material represented by CH 2 Cl 2 and is a material having high safety because it does not have a great harm to the environment and the human body.
이하, 상기와 같은 공정에 따른 폐 스치로폼의 재생공정을 보다 상세히 설명한다.Hereinafter, the regeneration process of the waste styrofoam according to the above process will be described in more detail.
폐 스치로폼을 간이 용해장치인 카세트식 저장탱크에 저장하여 연속 고성능 여과장치에 투입하고 폐 스치로폼에 부착된 불순물을 제거하여 배출시킨다.The waste styrofoam is stored in a cassette type storage tank, which is a simple dissolving device, placed in a continuous high performance filtration device, and the impurities are removed from the waste styrofoam and discharged.
불순물이 제거된 폐 스치로폼에 용제를 투여하고 분리장치로 이송하기 전에 예열기를 통과시켜 수지와 용제의 분리를 위한 예열을 한다.The solvent is injected into the waste styrofoam from which impurities have been removed, and then preheated to separate the resin and the solvent by passing through a preheater before being transferred to the separator.
예열된 용제와 폐 스치로폼을 분리장치에 투입하고 약 40℃의 온도로 가열하여 수분을 증발시키고 용제를 기화시키므로서 용제를 용제 저장탱크로 회수하여 수지와 용제를 분리하게 되는 것이다.The preheated solvent and waste styrofoam are put into the separator and heated to a temperature of about 40 ° C. to evaporate the water and vaporize the solvent, thereby recovering the solvent into the solvent storage tank to separate the resin and the solvent.
이때, 폐 스치로폼에 함유되거나 묻어있던 수분 역시 가열에 의해 증발하게되는 것이다.At this time, the moisture contained in the waste styrofoam or will be evaporated by heating.
용제와 수분을 제거한 수지를 수지흔련장치로 이송하여 겔상태로 압출하고, 이를 냉각시켜 절단하므로서 입자화된 파레트로 재생하게 되는 것이다.The resin is removed from the solvent and water is transferred to a resin kneading apparatus, extruded in a gel state, and cooled and cut to regenerate into granulated pallets.
상기에서 공정 중 회수된 용제는 회수용제 액화장치로 냉각시켜 다시 액화시키고 이를 회수용제 탱크에 저장하여 재사용하게 되는 것이다.The solvent recovered in the above process is cooled by the recovery solvent liquefaction apparatus to be liquefied again and stored in the recovery solvent tank for reuse.
상기와 같은 공정을 거쳐 재생된 발포스티롤의 인장강도 및 휨강도를 일반 발포스티롤과 비교하여 본 결과 아래 표1과 같은 결과를 얻을 수 있었다.As a result of comparing the tensile strength and the bending strength of the foamed styrolean recycled through the above process with the general foamed styrole, the results as shown in Table 1 below were obtained.
상기 표1 에서 나타난 바와 같이 본 발명의 제조공정을 거쳐 생산된 재생 발포스티롤이 일반 발포스티롤 보다 인장강도와 휨강도에서 크게 차이가 나지 않는 것으로 판명되어지므로 물성이 뛰어남을 알수 있다.As shown in Table 1, it can be seen that the regenerated expanded foam produced through the manufacturing process of the present invention is not significantly different in tensile strength and flexural strength than the general expanded foam.
상기와 같이 본 발명은 폐 스치로홈을 소각하지 않고 용제를 이용하여 재생시키므로서, 공정을 단순화하여 처리비용과 인력 및 시간을 최소화 할 수 있으며, 환경오염을 방지하고, 자원을 절약할 수 있는 것이다.As described above, the present invention can be recycled by using a solvent without incineration of the waste styro groove, thereby simplifying the process to minimize the processing cost, manpower and time, to prevent environmental pollution, and to save resources will be.
