METHOD OF PREPARING WASTE PLASTIC MOLDING

PURPOSE: A method for manufacturing a waste plastic molding is provided which not only reduces power consumption and generation of noise and dust but also increases strength of the waste plastic molding manufactured and improves moldability thereof by increasing processing efficiency of a waste cellulose based work. CONSTITUTION: The method for manufacturing a waste plastic molding comprises the steps of processing a waste cellulose based work in a flake shape, and compressing or compression molding the mixture by mixing the cellulose based work processed in a flake shape with powder of thermoplastic resins, wherein the cellulose based work is processed in a circular or elliptical flake having a diameter of 1 to 10 mm, 50 to 85 wt.% of the cellulose based work is added in the compression molding, the thermoplastic resins is one or more of resins selected from the group consisting of waste polyethylene, waste polyethylene terephthalate, waste polypropylene, waste polyvinyl chloride and waste acrylonitrile butadiene styrene, wherein the thermoplastic resin comprises waste polyethylene terephthalate, and the waste cellulose based work is at least one material selected from the group consisting of waste newspaper, waste magazine and waste milk pack. 본 발명은 폐플라스틱 성형체의 제조 방법에 관한 것으로, 폐셀룰로오스계 가공물을 지름 1∼10 ㎜의 원형 또는 타원형의 박편상으로 가공하고, 열가소성 수지의 분말과 혼합하여 압축 또는 압출 성형하는 단계를 포함하는 방법에 의하면, 폐셀룰로오스계 가공물의 가공 효율을 높임으로써 동력 소모를 감소시키고 소음, 분진 등의 발생을 줄이는 한편, 제조되는 플라스틱 성형체의 강도를 증가시키고 성형성을 향상시킬 수 있다.
