Study on the characteristics of pollutant emission from floor adhesive formulated using red clay

摘要

Development of building materials has been actively underway using natural materials in order to improve indoor air quality. Among such natural materials, red clay has been frequently used for development of building materials. In this study, 138 different environment-friendly adhesives were analyzed, aiming at determining the performance of adhesives prepared using red clay. The emission factors of formaldehyde and total volatile organic compounds (TVOCs) were examined for adhesives that had acquired the environment-friendly building materials certification before comparing with the characteristics of emission from red clay containing adhesives. In order to analyze pollutant reduction performance of the red clay adhesive, we exposed the clays to pollutants of formaldehyde and volatile organic compounds (VOCs), and analyzed the emission reduction performance due to adsorption on the red clay. The analysis results demonstrated the emission reduction performance of formaldehyde. Lastly, we compared the pollutant emission factors from multilayer building materials using red clay adhesive and general materials. The comparison results showed low emission factors for formaldehyde and VOCs. These results can be used as the basic data on performance characteristics of red clay adhesive.
