Abstract

It goes to be serious with environmental pollution because of great number of waste tires scrapped each you. That is why there are lots of studies for efficient recycle. We tried to reduce particle size of the waste tire powder using a new technology of self-designed grinding machine (SDGM) and ultrasonic treatment. The purpose of this study is to improve the physical properties of reduced waste tire powder. We investigated the fine powder by particle size distribution(PSD) analysis. And also we examined the physical and mechanical properties and cross-link density at various particle sire. Also we carried out morphological studies after making the products by SEM.

폐타이어의 증가로 인하여 환경문제가 날로 심각해지고 있다. 그러므로 효율적인 재활용을 통하여 이러한 문제를 해결하는데 많은 연구가 진행되고 있다. 본 연구에서는 폐타이어를 상온분쇄기를 제작하여 미세 분말화와 초음파로 처리를 통하여 기본물성을 높이는데 목적을 두었다. 폐고무 분말의 통계학적 분석에 의해서 미세화에 따른 물성의 변화와 물리적 성질을 조사하였고, 기계적 및 가교도 등의 물성을 조사하였다. 또한 광학현미경을 사용하여 표면을 확인함으로서 제품특성을 연구하였다.
