초록

국내에서 상당량 채취되는 천연 제올라이트를 신소재 개발을 위한 점토/유기물 복합체에 대한 고찰 측면에서 matrix 수지를 ABS로 하고 이의 충진재로의 특성을 살펴 보았다. 결과, 제올라이트의 입자 크기는 200∼300mesh(48∼74micron)가 적절하였그, 제올라이트 함랑이 증가하면 인장 및 굴곡탄성률은 증가하지만 인장, 굴곡, 충격강도는 감소하였다. 이러한 강도의 향상을 위해 silane계나 zircoaluminate계 coupling agent가 모두 효과적으로 강도 향상이 이루어졌으며 이는 제올라이트와 ABS 계면이 잘 접착되어진 것으로 SEM 사진으로 확인되었다. 특히, amino-functional silane과 methacry]oxy-functional zircoaluminate가 유효하였으며 이를 이용한 제올라이트 충진 ABS 복합수지는 상업적 사용이 가능할 것으로 판단된다.

In this study, ABS(Acrylonitrile Butadiene Styrene) material was used as a matrix polymer and a series of natural zeolite with wide variety of contents, size and coupling agents were blended together. Based on the specified compositions, changes in the mechanical property and morphology were investigated. The results indicated that optimum size of natural zeolite for mechanical property and handling was between 200 and 300 mesh. And it was found that the increased content of natural zeolite results in higher modulus with the reduced mechanical strength ( tensile, flexural and impact). The surface treated zeolite by zircoaluminate coupling agent, on the other hand, showed improvement in modulus and strength of this system and this was confirmed by SEM picture showing the enhanced interfacial adhesion between the components. Silane of amino-functional group and zircoaluminate of methacryloxy-functional group were effective as coupling agents.
