영어 초록
In recent years, the number of complaints about indoor air pollution caused by volatile organic compounds(VOCs) has increased. It is important that evaluating and understanding emission of indoor air pollutant from building materials. The aim of this study was to evaluate emission test methods for liquid phase building materials such as paint, adhesive and sealant, and to determine the emission of total volatile organic compounds(TVOC) from liquid phase building material. The quantity of TVOC emission was measured by a gas chromatography/mass spectrometry (GC/MSD). It was found that liquid phase building materials were classified according to their use and ingredient. The TVOC concentration from oil-based paint was the highest among 8 groups of test materials. The unidentified volatile organic compounds occupied 83.0% of TVOC emission from test materials. The aliphatic hydrocarbons and aromatic hydrocarbons occupied 7.2%, 6.9% of TVOC, respectively. The concentration of TVOC decreased by an increase during emission test period. After 3 days, the concentration of TVOC from paint, adhesive and sealant were about half of the concentration at the first day. The ratio of concentration between 7 days and 1 day was 0.11~0.15 from water-based paint and 0.46~0.48 from epoxy adhesive.
