무기질도료의 흡착‧흡방습 성능향상 기술시스템에 관한 연구

Abstract

Recently, functional building materials which are made of sorption materials have been widely used as board products, inorganic paints and wall papers. These remove chemical substances(VOCs, HCHO) from indoor air by physical sorption or chemical reaction and control humidity by capillary condensation. Also these materials have been used as countermeasures to sick building syndrome (SBS). However, in case of using internal building materials, the hazardous substances affecting to indoor air quality are emitted from not only the material itself but also the subsidiary materials such as adhesives for construction. Particularly in case of wallpaper and flooring material, the amount of emission from adhesives for construction is larger than that from the material itself. Therefore, this research tried to develop a technology system that can improve the performance of adsorption, absorption and desorption of moisture including the construction process that can affect to indoor air quality. To attend this end, ‘porous securement manufacturing technology system’ and ‘porous keeping construction technology system’ are developed that can secure more micropores in the process of production and construction of inorganic paint and maintain them. Consequently the reduction performance of chemical substances(VOCs, HCHO) concentrations and the humidity control performance improved almost over 30% by the technology system of the Inorganic paint.
