Abstract

We have developed measurement method of VOC emission rate from adhesive by using diffusion property of calcium silicate board. In this paper, we measured emission rates of 3VOC (Toluene, m-Xylene, Ethylbenzene) from four kinds of adhesives for various additive amount conditions. For all adhesives and for all VOCs, the emission rates of 1 day later were the highest of all, and then, they decreased as time goes by. The measured values of emission rate were reproducible after 3 days or later. Besides, the emission rates from adhesive U (Polyurethane resin) and S (Chloroprene rubber) showed similar exponential decay tendency. On the other hand, the emission rates from adhesive E (Epoxide resin) and W (Ethylene vinyl acetate emulsion copolymerization) hardly attenuated since 3 days later. Content and emission late of 3VOC were correlated after 3 days or later. However, for adhesive U and S, they didn't be correlated until 5 or 7 days later. Additionally, the more VOCs were added, the higher emission rate was.
