폐 갈분을 이용한 친환경 합성목재 성형을 위한 원료 배합 기술 개발 및 특성 평가

Wood plastic composite (WPC) has attracted increasing research attention because they can be substitute for the materials in various residential construction industry and furniture industry due to the environmentally friendly and economical feasibility. In this work, ecofriendly WPC was developed using waste reed flour prepared by melt-mixing and compression molding. Effect of compatibilizer contents, mixing ratio of polymer metrics for WPC was investigated by measuring mechanical properties, morphology and water absorption. The mixing ratio of 1:3 for LDPE:Homo PP with 6-7 wt% compatibilizer has high strength and good moldability because of low porosity in WPC body and good dispersity of reed flour in polymer metrics.
