Abstract

Environmental problems due to waste tire and waste plastics let us develop practical and economically feasible products. For this purpose, the characteristics of waste tire/plastic composites including various additives were examined using internal mixer. Experimental results indicated that the tensile strength and the flexural strength of waste tire/plastic composites decreased with the waste tire content. When 20 wt% of PP was added to the waste tire (60 wt%)/HDPE composites, the tensile strength was 1.5 times higher than the composite without PP, It was also found that the strain at break of composites increased by 2.5 times with 10 wt% addition of ethylene vinyl acetate and styrene ethylene butylenes styrene respectively. When 10 wt% of glass fiber was added to waste tire (60 wt%)/ HDPE composites, the tensile strength was 63% higher than the composite without glass fiber.

폐타이어와 폐플라스틱을 이용한 환경문제 해결과 실용적이고 경제성 있는 재활용품 개발을 목적으로 수행되었으며 밀폐식 혼합기를 이용 폐타이어와 폐플라스틱을 첨가제와 함께 혼합하여 플라스틱 재질별, 폐타이어 함량별 차이에 따른 복합소재 특성을 규명하고자 하였다. 폐타이어/플라스틱 복합소재 실험 결과, 플라스틱 대비 폐타이어 함량을 15 wt%씩 증가시킴에 따라 복합소재의 인장강도와 굴곡강도의 세기는 점차 감소하였으며 신장율은 플라스틱 재질별로 차이가 있었다 폴리프로필렌과 같은 유기첨가제를 폐타이어 (60 wt%)/고밀도 폴리에틸렌 복합소재 전체함량 대비 20 wt% 혼합하였을 때의 인장강도가 폴리프로필렌를 투여하지 않은 복합소재보다 1.5배 높게 나타났으며 에틸렌 비닐아세테이트와 스티렌 에틸렌 부틸렌 스티렌을 각각 10 wt% 첨가 시 2.5배의 신장율이 증가하였다. 또한 무기첨가제 유리 섬유를 폐타이어 (50 wt%)폐고밀도 폴리에틸렌 복합소재 전체함량 대비 10 wt% 첨가 시 굴곡강도가 첨가제가 투여되지 않은 복합소재 굴곡강도보다 63% 높게 나타났다.
