본 명세서는 폴리염화비닐 추출용 용매의 스크리닝 방법, 폐기물의 재활용하는 방법, 재활용된 폴리염화비닐 및 조성물에 관한 것이다.
플라스틱은 열 또는 압력에 의하여 다양한 모양으로 성형할 수 있고, 재질의 품질이 점점 좋아지고 있어 일상생활 전반의 물건을 플라스틱으로 대체하거나, 이를 사용한 새로운 물건이 개발되고 있다.
이러한 플라스틱은 편리하고 사용이 간편하여, 전세계적으로 비닐봉투, 페트병, 일회용품, 포장제품, 전자제품 등 플라스틱으로 만든 제품의 수요가 점차 증가하고 있다.
이렇게 사용되고 버려진 플라스틱은 소각하거나 매립되는 데, 소각하는 경우에는 인체에 유해한 오염물질이 많이 배출되므로, 버려진 플라스틱은 소각보다는 매립하게 된다.
그러나, 대부분의 플라스틱은 폐기 후 자연 분해에 오랜 시간이 소요되는 데, 매립되는 플라스틱의 양이 상당하기 때문에, 플라스틱 재활용에 대한 관심이 증가하고 있다.
플라스틱 중에서, 폴리염화비닐(PVC)는 건축자재(파이프, 창틀 등), 전선피복, 합성피혁, 고무대야, 호스, 바닥재, 포장재, 의료용 수액 주머니, 장난감 등에서 많이 사용되고 있다. PVC를 포함하는 폐기물로부터 PVC를 재활용하기 위한 다양한 방법과 재활용과정에서 인류와 환경에 줄 수 있는 피해를 최소화할 수 있는 물질을 모색해야 한다.
본 명세서는 폴리염화비닐 추출용 용매의 스크리닝 방법, 폐기물의 재활용하는 방법, 재활용된 폴리염화비닐 및 조성물을 제공한다.

또한, 폴리염화비닐 제조시에 최종품의 총 중량을 중심으로 약 20중량% 내지 50중량%의 가소제가 투입된다. 폐기물로부터 PVC를 추출하기 위해서는 무시할 수 없는 함량으로 첨가된 가소제의 특성을 고려하는 것이 바람직하며, 폐기물로부터 PVC를 추출할 때 가소제와 용해도가 높다면 더 많은 PVC를 추출할 수 있는 장점이 있으므로, 상기 식 1 내에 가소제와 용매의 상호작용에 관한 인자가 포함되어 있다.
본 명세서의 일 실시상태의 식 1에서, 화학퍼텐셜은 COSMO-RS(Conductor like Screening Model for Real Solvents) 이론을 이용하여 계산할 수 있으며, COSMO-RS는 단분자(unimolecular) 양자 화학적 계산에 기반을 두어 분자 구조 정보로 각 용매의 특성인 열역학 데이터를 예측한다. 이를 간편하게 계산해주는 COSMOtherm 소프트웨어(COSMOlogic GmbH & Co. KG社)을 사용하여 계산할 수 있다.
본 명세서의 일 실시상태의 식 1에서, ri는 용매와 용질i 간의 한센 용해 파라미터 거리이며, 하기 식 2를 통해 계산된다. rpvc는 용매와 PVC 간의 한센 용해 파라미터 거리이며 PVC와 용매가 얼마나 유사한지를 나타낸다. rdop는 용매와 가소제 간의 한센 용해 파라미터 거리이며, 가소제와 용매가 얼마나 유사한지를 나타낸다. 서로 유사한 성질을 가질수록 상용성이 높을 것으로 판단하고 ri가 작을수록 서로 유사할 것으로 판단한다.

본 명세서의 또 다른 실시상태는 상술한 조성물을 여과하여 수득한 재활용된 폴리염화비닐을 제공한다.
본 명세서의 또 다른 실시상태에서, 폐폴리염화비닐 재활용 조성물 내에서 폴리염화비닐을 포함하는 폐기물로부터 상기 양용매에 의해 추출된 폴리염화비닐은 비용매에 의해 대부분의 폴리염화비닐이 석출되어 고체상태로 가라앉아 있을 수 있다. 이렇게 석출된 상태의 폴리염화비닐을 포함하는 조성물을 여과하여 재활용된 폴리염화비닐을 수득할 수 있다.
본 명세서의 또 다른 실시상태에서, 재활용된 폴리염화비닐은 상기 조성물을 여과한 상태이거나, 여과 후 건조하여 여분의 용매들을 제거한 상태를 모두 포함한다.
본 명세서의 일 실시상태에 있어서, 상기 재활용 폴리염화비닐은 폐기물로부터 유래된 첨가제를 포함한다. 이때, 상기 폐기물로부터 유래된 첨가제는 폐기물을 제조하기 위해 추가되었던 첨가제라면 특별히 한정하지 않으나, 예를 들면 가소제 등이 있다. 상기 재활용된 폴리염화비닐을 활용하여 제품을 생산 시 이미 가소제 등의 첨가제가 포함되어 있어 가소제 등의 첨가제를 넣지 않거나 첨가량을 줄일 수 있는 장점이 있다.
본 명세서의 일 실시상태에 있어서, 상기 폐기물은 PVC를 포함하고 있다면 특별히 한정하지 않으나, 예를 들면 PVC를 포함하는 건축자재(파이프, 창틀 등), 전선피복, 합성피혁, 고무대야, 호스, 바닥재, 포장재, 의료용 수액 주머니, 장난감 등일 수 있다.
본 명세서의 일 실시상태에 있어서, 상기 재활용된 폴리염화비닐은 용매 추출에 의해 추출된 PVC로서, 용매에 의한 추출 시 저분자량의 PVC들이 필터링되어 중합에 의해 제조된 PVC 또는 폐기물 내 PVC보다 평균분자량이 높아진다. 또한, PVC의 평균분자량이 변화하여 이의 유리전이온도(Tg), 용융온도(Tm) 등과 같이 평균분자량에 영향을 받는 동적 물성이 변화하므로, PVC의 평균분자량이 증가할수록 유리전이온도(Tg), 용융온도(Tm) 등의 동적 물성도 증가한다.
이하에서, 실시예를 통하여 본 명세서를 더욱 상세하게 설명한다. 그러나, 이하의 실시예는 본 명세서를 예시하기 위한 것일 뿐, 본 명세서를 한정하기 위한 것은 아니다.

은 용매, pvc, dop 분자 구조를 바탕으로 Turbomole 프로그램을 이용하여 분자 표면 전하 분포를 계산하여 얻고 이를 통해 COSMOtherm 프로그램을 이용해 해당값을 계산했고, Vsol도 용매의 구조를 바탕으로 COSMOtherm을 통해 계산했다.
rpvc 및 rdop은 각각의 분자 구조를 SMILES 형태로 HSPip 프로그램에 입력하여 도출된 Hansen solubility parameter 결과값을 식 2에 대입하여 각각의 값을 계산했다.

상기 표 2에서, 문헌값 (δADBP)은 상기 #1의 4번식 δADBP값이며, 실험값 (Q)은 상기 #1의 표 1에 기재된 swelling ratio값이다. 실험값(Q)가 클수록 PVC를 실험에서 잘 용해 시키는 용매이고 Diss의 경우 완전히 용해시키는 경우이다.해당 문헌에서 판별하는 파라미터로 δADBP를 사용하고 값이 2.2보다 작은 경우 good solvent로 판단하지만 해당 값의 경향과 실험 값의 경향이 일치하지 않는다.
상기 표 2에서, δADBP값이 2.2이하인 1.347값을 갖는 good solvent로 판단된 pyridine은 δADBP값이 2.11인 THF보다 낮은 값을 가져 용해도가 높다고 예측할 수 있다. 그러나, 실험값(Q)가 δADBP값이 2.11인 THF는 diss로 완전히 용해되었고, δADBP값이 1.347 pyridine은 15.04를 나타내어 THF보다 용해가 잘되지 않는 것을 확인할 수 있다.
반면, 본 명세서의 식 1에 따른 PVC solubility score값은 높을수록 PVC에 대한 용해도가 높은 용매로 판단하며, 기준의 예시로 13 이상이면 양용매로 9 이하이면 비용매로 판단할 수 있다.
상기 표 2에서, 식 1에 따른 THF의 PVC solubility score값은 13.4063으로 PVC solubility score값이 12.9354인 pyridine보다 높은 값을 나타내며, 양용매의 예시기준으로 판단할 때, THF는 양용매이나, pyridine은 양용매가 아닌 용해의 효용성이 낮은 용매로 예측되고, 이는 실험값과도 일치되어 본 명세서의 식 1의 신뢰도가 높음을 확인할 수 있다.
도 2는 본 명세서에 따른 식 1로 계산된 PVC solubility score값과 PVC swelling ratio의 관계를 도시한 그래프이다.
여기서, PVC swelling ratio는 실험을 통해 상기 #1의 식 1로 계산된 값으로, 해당 값은 #1의 문헌 표 1에서 발췌했다.
[실험예]
PVC 폐기물 시료를 하기 표 3의 양용매에 첨가하여 상온에서 3시간 동안 120rpm으로 교반하여 용해액을 제조했다. 이후, 상기 용해액에 하기 표 3의 비용매를 드랍하여 PVC를 침전시켰다. 이때, 폐PVC:양용매:비용매의 중량비는 1:5:20이며, 양용매 중 주용매와 보조용매의 중량비는 60: 40이다.
비용매를 모두 드랍한 후 반응액을 필터로 여과하여 여과된 고체를 수득했다. 여과된 고체를 상기 비용매와 동일한 비용매로 추가 수세하고 건조하여 재생 PVC를 얻었다.

표 3에서 사용된 용매들의 PVC solubility score값은 하기 표 4와 같다.
표 4의 PVC solubility score값을 참고하여 표 3을 살펴보면, dichloromethane(MC)의 경우 PVC solubility score가 사용된 양용매 중에서 가장 낮으며, 즉 PVC의 용해도가 실험예의 양용매 중 가장 낮은 것을 의미한다. 따라서 dichloromethane(MC)를 보조용매로 사용한 실험예 2 및 3은 주용매가 cyclohexanone이고, 보조용매가 N,n-dimethylpropanamide(DMPA)인 실험예 1보다 회수율이 낮은 것을 확인할 수 있다.
