Sažetak
The paper reports on research on the use of nanaoparticles titanium-dioxide (TiO2) and zinc-oxide (ZnO) as UV absorbers in polyacrylate water borne stain in the colour and gloss stabilisation, and appearance of cracks of thermally modified and unmodified beech wood. Unmodified and thermally modified beech wood at 190 °C and 212 °C coated with three types of coatings in which nanoparticles are added were exposed 840 h to UV radiation, water spray and humidity using QUV tester equipped with UVA-340 fluorescent lamps. Before and after 168, 336, 504, 672, and 840 hours of accelerated weathering changes in colour and gloss, and the appearance of surface cracks were measured on the samples. Colour change (E*) was recorded on all tested wood samples after accelerated exposure. It has been established that the coating with TiO2 nanoparticles reduced colour changes of thermally modified beech wood. After accelerated exposure the gloss decreased in all samples regardless of the type of used coating.
