주거용 실내 내장재의 산소지수농도에 관한 연구

Abstract

Interior material has become diverse with the development of industrial society. However, since it has been focused on design and economic feasibility than security, it easily burns and occurs toxic gas which causes the damage for humans and of property in case of fire. Therefore, this research used oxygen index for figuring out combustion nature of wallpaper and flooring material which are being widely used as interior material. The result is as below. 1) As measurement result of oxygen index concentration in case of wallpaper, each wallpaper showed as follows hanji wallpaper 16.9 %, silk wallpaper 18.7 % and joint wallpaper 18.7 %. 2) In case of flooring material, the concentration degree of oxygen index was the highest as follows monorium linoleum 22.5 %, ondol floor 29.3 % and laminated floor 32.3 % 3) In terms of the result of flame-resistance, the oxygen index of laminated floor was estimated as the highest and hinji wallpaper was the lowest. 4) Considering 21.0 % of oxygen concentration in the air, wallpaper types was easily burn however, all of the flooring material was burn from above 21.0 %. It shows that flooring material resists the expansion of combustion in a fire. 5) Since wallpaper type contains low oxygen index concentration, it is needed to be produced with adding flame-resistance aterials for preventing fire expansion.
