Zusammenfassung:The present invention suggests a method for preparing recycled plastics by pulverizing, washing, and drying film-sheet-type domestic waste plastics, injecting a compatibilizer to the dried waste plastics, and extruding the same. More specifically, the present invention relates to a method for recycling film-sheet-type domestic waste plastics. The method comprises: a first step of pulverizing film-sheet-type domestic waste plastics; a second step of washing and drying the pulverized waste plastics; a third step of preparing raw materials for recycled plastics by stirring the waste plastics and a compatibilizer; and a fourth step of extruding the stirred raw materials. According to the present invention, in recycling waste plastics, a sorting and separation operation by material, which is usually preceded, is not conducted. Accordingly, a process can be simply and quickly carried out, and at the same time, economic feasibility and productivity can be improved. 본 발명은, 필름 시트형 생활계 폐플라스틱을 분쇄하여 세척, 건조한 후 상용화제를 투입하여 압출함으로써 재생 플라스틱을 만드는 방법을 제한한다. 구체적으로, 본 발명은 필름 시트형 생활계 폐플라스틱 재생방법에 관한 것으로서: 필름 시트형 생활계 폐플라스틱을 분쇄하는 제1단계; 상기 분쇄된 폐플라스틱을 세척, 건조하는 제2단계; 상기 폐플라스틱과 상용화제를 교반하여 재생 플라스틱 원료를 만드는 제3단계; 상기 교반된 원료를 압출하는 제4단계를 포함한다. 본 발명에 따르면, 폐플라스틱을 재생함에 있어 통상 선행되는 재질별 구분 및 분리 작업을 거치지 않음으로써, 공정이 간단하고 신속하게 이루어지며 동시에 경제성·생산성이 향상되는 효과가 있다.
