Abstract

In this study, waste polypropylene and waste ground rubber tire(WGRT) composites were prepared by using a modular intermeshing co-rotating twin screw extruder. The effect of three main factors such as WGRT contents, particle size, compatibilizers on the properties of waste PP/WGRT composites was extensively investigated. Tensile strength of the composites was decreased with an increase in WGRT contents, whereas elongation at break and impact strength were increased. The tensile strength, elongation at break and impact strength of the composites with the smaller size of the WGRT were more enhanced. Addition of PP-g-MA into waste PP/WGRT composites exhibited better tensile strength. However, elongation at break and impact strength were slightly decreased with increasing of PP-g-MA. On the other hand, tensile strength, impact strength and elongation at break of the composites were increased by adding the EPDM-g-MA and SEBS-g-MA. Especially, elongation at break was significantly increased compared to the composite with PP-g-MA.

본 연구에서는 이축 스크류식 치합형 압출기를 이용하여 재생 폴리프로필렌/폐타이어 분말 복합체를 제조하였다. 세 가지 주요 실험 변수 즉 폐타이어 분말 함량, 폐타이어 분말 크기, 상용화제의 종류 및 함량이 재생 폴리프로필렌/폐타이어 분말 복합체의 물성에 미치는 영향을 자세히 관찰하였다. 폐타이어 분말의 함량이 증가 할수록 인장강도는 감소하였으며 신장률과 충격강도는 증가하는 것이 관찰되었다. 또한 폐타이어 분말의 크기가 작아질수록 인장강도 및 신장률, 충격강도는 증가하였다. PP-g-MA를 첨가 하였을 시 복합체의 인장강도는 증가하였지만 신장률과 충격강도는 감소하였다. 반면에, 상용화제 EPDM-g-MA, SEBS-g-MA의 경우에는 복합체의 인장강도, 충격강도가 증가하였고 신장률은 PP-g-MA와 비교했을 때 매우 큰 폭으로 증가하는 것이 관찰되었다.
