Study of construction convergence technology for performance improvement in functional building materials

When using internal building materials, hazardous substances that affect indoor air quality are emitted from not only the material itself, but also from subsidiary materials such as construction adhesives. For wallpaper and flooring material, emissions from adhesives exceed the emissions from the material itself. Recently, functional building materials with absorption properties have been widely used in board products, inorganic paints and wall-papers. These materials remove chemical substances from indoor air through physical sorption or chemical reaction and control humidity through capillary condensation. These materials have been used as countermeasures to sick building syndrome. This study was conducted on inorganic paint, which is a functional building material that received New Excellent Technology certification for its moisture absorption and desorption performance. This moisture property affects the humidity in the indoor air and adsorbs formaldehyde and volatile organic chemicals. In this study, a construction convergence technology that can improve performance by at least 30% is proposed based on the principles of moisture absorption and desorption. The findings of this study confirmed the importance of convergence technology that organically interconnects manufacturing and construction technologies to improve and maintain the performance of functional building materials.
