摘要:
The present invention relates to a method of manufacturing an eco-friendly high-functional biodegradable film using by-product gypsum and a film produced therefrom, in which raw materials of limestone, polybutylene adipate-coterephthalate (PBAT), and poly lactic acid (PLA) are added for each raw material tank. A) The input and storage step of raw materials stored in the state, the limestone, PBAT and PLA stored in each raw material tank are automatically weighed through a meter and fed to the mixing device to be mixed to form a mixture constituting the film And the resulting mixture is transferred through the heating transfer unit of the die extruder b) mixing of raw materials, the mixture is transformed into a viscous film in the process of transferring the mixture through the heating transfer unit of the die extruder As entering the device, c) the film blowing step of the mixture, which is inflated and rises in the form of a cylinder having a blowing shape according to the blowing and spraying of the antibacterial liquid, the blown film passes through the corona treatment device and undergoes corona discharge treatment, The discharge-treated film is antibacterial through impregnation in an impregnation tank d) Discharge and antibacterial treatment of the film, and the antibacterial-treated film is collected through a meshing roller and wound through each decomposition roller. In addition to the manufacturing method of an eco-friendly, highly functional biodegradable film using by-product gypsum including the step of e) winding the film, an eco-friendly and highly functional biodegradable film manufactured by the above manufacturing method is to be provided.본 발명은 부산물 석고를 이용한 친환경 고기능성 생분해 필름의 제조방법 및 이로부터 제조된 필름에 관한 것으로, 각 원료탱크별로 석회석, PBAT(Polybutylene adipate-coterephthalate) 및 PLA(Poly Lactic Acid)의 원료들이 투입되는 상태로 보관되는 a) 원료들의 투입 보관 단계, 상기 각 원료탱크에 보관된 석회석, PBAT 및 PLA가 계량기를 통해 자동 계량되는 방식으로 혼합장치에 공급되어 혼합되는 과정을 통해 필름을 구성하는 혼합물로 생성되고, 생성된 상기 혼합물이 다이스 압출기의 가열이송부를 통하여 이송되
