Abstract
Recently, there has been an increased concern, such as environmental issue, our health and safety. In living environmental, it becomes social problem as sick-building syndrome which occurs by indoor air quality containing harmful substances. In previous study, in order to make the high quality building materials using chitosan, chitosan-hybridized acrylic resins were prepared in the emulsion polymerization. The interior finishing coating made from the chitosan-hybridized acrylic resins passed the test of JIS K 56632003 for an interior finishing coating and showed excellent adsorption ability for formaldehyde. In this study, in order to evaluate the adsorption ability for the formaldehyde of chitosan-hybridized acrylic resins, emission factor after adsorption was examined. Emission factor of chitosan-hybridized acrylic polymer and interior finishing coatings using this after adsorption of formaldehyde were less than 20μg/m2·h under various temperature and humidity. Further, the formaldehyde which absorbed to chitosan is considered to be chemically stable from a FT-IR spectrum.
