디자인, 공예 분야에서 폐산업소재의 새로운 가능성에 대한 작품연구 -폐플라스틱 가루 실험 사례를 중심으로-

Abstract

Plastic materials have enriched our lives as they are used in various industrial areas, from goods necessary for our daily lives to the industry field, but environmental pollution has been steadily pointed out. The purpose of this study is to explore ways to utilize waste plastic and to confirm the possibility of new forms and materials texture. As a research method to understand plastic materials and explore the direction of experiments, first, research on the characteristics of plastic types and areas mainly used was done. Second, recycled plastic products that deal with sustainability issues since the 2000s was researched. This study experimented with a method of chemically dissolving waste plastic powder generated in design prototype processes such as 3d printing and CNC processing using acetone (CH3COCH3), an alcoholic solution. The plastic type, acrylonitrile butadiene styrene (ABS), which is most commonly used in the prototype process, was selected because of its ease of processing and easy dyeing. The waste plastic powder with a relatively large surface area could be easily dissolved in a sealed container with a small amount of acetone vapor in a short time. Waste plastic powder of various shapes and sizes melted in a solvent, creating an unintended surface texture, and using color pigments, the desired color could be realized. It was made a bowl shape with a metal mold, and the desired color could be dyeid as a color pigment used in clothing or resin. This was a discovery of the aesthetic potential of plastic materials that were not found in previous recycled plastic products. The results made using waste plastic powder which are meaningful in that plastic materials that are difficult to recycle can be easily recycled without classifying even a small amount of impurities, resulting in a new interpretation of plastic materials in visual and texture.
