Abstract
This contribution investigates the problematic of indoor air pollution. There were tested low emitting types of lacquers – UV and waterborne lacquers. The work has been splitted in to two parts. In the first part samples of lacquers were applied on the particle board with beech veneer on the surface. Samples of air with VOCs (Volatile Organic Compounds) from lacquers were taken 3 and 24 hours after application. Tests proved that film layer of UV lacquer emit much smaller volumes of VOCs than acrylic waterborne lacquers or than 2–component epoxide waterborne lacquer. Acrylic waterborne lacquers’ materials emitted especially butoxyethylene, epoxide lacquer emitted a lot of butoxyethanol and methoxypropanol and UV lacquers particularly emitted toluene, benzene and xylene. Second part of testing consists of VOCs’ measuring of chosen lacquers applied on different base materials – inertial material glass and particle board with beech veneer. Tested criterion was the impact of different base material on emitted amount of VOCs. The results showed that lacquer coated on glass emit much more chemicals than lacquer on wood material. All materials were also tested on total amount of organic compounds emitted in to the air – on the TVOC. Measuring showed the same results as the first parts of research.
