Abstract

From the point of view of indoor air pollution, it is necessary to investigate systematically the emissions of volatile organic compounds from natural building materials. Especially, the emissions of volatile organic compounds from natural liquid materials were taken up and researched, because liquid materials such as paints or adhesives often cause troubles. As a result of this research, it was known that there were some types of aldehyde・ketone emissions after paintings of natural liquid materials. Pine resin, urushi, linseed oil and vegetable oil wax on the market showed typical 4 types of emissions, those were the simple emission controlled by a vaporization, the emission from a coating film, the emission accompanied by an oxidation and the emission accompanied by an oxidation with a time lag. The mechanisms of aldehyde・ketone emissions from these materials were discussed. For the forecasts of long term emissions from natural liquid materials, the considerations of these emission types are necessary.
