Abstract
국내 건축물 마감재는 국토교통부 고시에 따라 KS F 2271 기준에 의해 평가되어지고 있으며, 이 실험은 실험동물을 사용하여 평가하고 있다. 본 연구에서는 가연성이 높은 유기물 단열재 EPS, 우레탄, 페놀폼에 대해 실험을 진행하였다. 이 3종의 단열재가 연소 시 발생되는 유해성 가스에 의한 실험용 쥐의 평균행동정지시간을 측정하여, 실험용 쥐의 행동정지에 대한 원인을 분석하고자 하였다. 실험용 쥐의 행동정지에 대한 원인분석방법으로는 FTIR 분석과 연기밀도실험을 진행하였고, 마우스의 행동정지 원인을 입자상물질에 의한 질식과 가스상물질에 의한 독성흡입으로 구분하여 실험결과를 분석하였다. 실험결과 우레탄이 가장 유해한 단열재로 평가되었으며, 가스유해성 실험결과에 대한 원인분석으로 FTIR분석과 연기밀도 실험을 진행한 결과, 독성흡입에 의한 영향보다 질식에 의한 실험용 쥐의 행동정지가 높은 것으로 나타났다. 본 연구는 유해성가스의 원인분석에 대한 기초연구로서, 독성의 근거를 마련하고 나아가 다양한 재료와 가스에 대한 분석을 통하여 보다 구체적인 독성평가의 기준이 마련될 수 있을 것으로 기대된다.
Domestic building finishing materials are being evaluated according to KS F 2271 standards according to the notification of the Ministry of Land, Infrastructure and Transport, and this test is evaluated using laboratory animals. In this study, experiments were conducted on highly combustible organic insulation materials such as EPS, urethane, and phenolic foam. The purpose of this study was to analyze the cause of the behavioral suspension of the experimental mice by measuring the average behavioral suspension time of the mice caused by the harmful gas generated when these three types of insulation materials were burned. FTIR analysis and smoke density experiment were performed as a cause analysis method for the behavioral suspension of mice, and the experimental results were analyzed by dividing the causes of behavioral suspension into suffocation by particulate matter and toxic inhalation by gaseous substances. As a result of the test, urethane was evaluated as the most harmful insulation material, and as a result of FTIR analysis and smoke density test as a cause analysis for the gas toxicity test results, it is judged that the behavioral stop of the rats by suffocation is higher than the effect of toxic inhalation. This study is a basic study on the cause analysis of harmful gases, and it will be necessary to prepare the toxicity basis and analyze various materials and gases.
