상용차 타이어 제조 처방에 따른 미세먼지 발생 경향 연구
Study on the Generated Particular Matters of TBR Tire with Different Tread Rubber Formulation

초록
자동차 비배기계 미세먼지는 브레이크 및 타이어 마모에 의해 주로 발생되는 것으로 알려져 있다. 배기계 미세먼지와 달리 도로상에서 타이어 마모에 의해 발생되는 미세먼지는 대기중 농도가 낮으며, 성분분석을 위한 추적 물질의 부재 등으로 인하여 정확한 분석이 매우 어려운 실정이다. 본 연구에서는 타이어 마모와 미세먼지 발생량의 연관성을 분석하기 위하여, 각기 다른 배합조건으로 타이어 시료를 준비하고, 강제적으로 마모하여 이때 발생되는 미세먼지의 함량과 경향을 분석하였다.
It is known that particular matter from the vehicle’s non-exhaust emission is mainly generated by wear of brakes and tires. Unlike particular matters from exhaust system, the one generated by tire wear on the road is very difficult to accurately analyze due to the absence of traces and low concentration in the atmosphere. In this study, in order to analyze the relationship between tire wear and the amount of particular matters generated, samples were prepared with various recipes and under different mixing conditions. Generated particular matters by abrading tires or specimens were analyzed by aerodynamic particle sizer.
