Abstract

The waste tire powder is modified with allylamine in the presence of ultraviolet radiation and the influence of surface modification on the thermal and rheological properties of polypropylene/waste tire powder composites was investigated. X-ray diffraction studies of PP/waste tire powder composite without compatibilizer, such as maleic anhydride-g-polypropylene (MA-PP), shows the increase in peak intensity of ${\beta}$ crystalline peaks, whereas it completely disappears in the presence of the MA-PP. Differential scanning calorimetry results further supported the above fact. The melt viscosities and storage modulus of the composites with modified waste tire powder show higher value than that of composites with unmodified powder and it is attributed to the interaction between amine group on modified powder surface and maleic anhydride of MA-PP.

Allylamine을 이용하여 UV하에서 폐타이어 분말을 개질하였으며, 이를 이용한 PP/폐타이어분말 복합체의 열적, 유변학적 성질을 분석하였다. X-ray 분석결과 무수말레 산이 그라프트된 폴리프로필렌과 같은 상용화제가 없는 경우 ${\beta}$ 결정의 피크 강도가 증가한 반면 상용화제가 있는 경우 완전히 없어짐을 알 수 있었으며, DSC 결과에서도 이를 확인할 수 있었다. 개질된 폐타이어 분말을 함유한 복합체의 용융점도와 탄성모듈러스는 개질되지 않은 분말을 함유한 복합체 보다 높은 값을 나타내었으며, 이는 개질된 분말 표면의 아민기와 말레이산이 그라프트된 PP의 상호작용에 기인하는 것으로 판단된다.
