Abstract

In present, evaluation method for car cabin air quality has been developed in ISO, China, Japan. Also The management standard for new produced car has been applied since 1, July, 2010. To manage car cabin air quality, It is important to evaluate VOC emitted from interior material. In this study, complete component of door trim armrest was evaluated in accordance with ISO 12219-5, cut component was evaluated in accordance with ISO 12219-3. The vapour gas was collected with stainless tube packed with Tenax TA and analyzed with TD-GC/MS. It was confirmed that emission rate of each compounds was difficult in each evaluation method. As a result, to evaluating each components composing door trim armrest, main sources of emitting VOCs in door trim armrest were PP substrate and adhesive.

현재 자동차 실내공기질을 평가하는 방법이 ISO, 중국, 일본에서 개발 중에 있으며, 우리나라에서도 관리기준이 2010년 7월 1일 이후 생산한 신규제작자동차부터 적용되고 있다. 자동차 실내공기질을 관리하기 위해서는 자동차 실내의 내장부품으로부터 방출되는 휘발성 유기화합물을 평가하는 것이 중요하다. 이 연구에서는 모듈단위부품인 도어트림 모듈의 구성부품인 도어트림 암레스트를 ISO 12219-5방법에 따라 완제품을 평가 하였으며, ISO 12219-3방법으로 절단부품과 도어트림 구성소재를 평가하였다. Tenax TA가 충진된 스테인리스 튜브를 이용하여 VOC를 채취하여 TD-GC/MS를 이용하여 분석하였다. 두 시험방법을 비교한 결과 도어트림 암레스트로부터 방출되는 물질의 비율이 차이가 있음을 확인하였고, 도어트림 암레스트의 소재를 평가한 결과 PP substrate과 adhesive가 도어트림 암레스트에서 주요 방출원인 소재로 나타났다.
