Abstract

Drvo kao prirodni materijal je podložno razgradnji pod utjecajem vremenskih uvjeta. Jedan od najznačajnijih čimbenika je UV svijetlost koje svojim djelovanjem kemijski razgrađuje drvo te utječe na promjenu njegovih svojstava kao što su: boja, sjaj, tvrdoća površine. Stoga se drvo zaštićuje raznim premazima da bi se produžio njegov vijek trajanja i da bi duže zadržalo određena svojstva. Kod takvih premaza javlja se potreba za svojstvima koja omogućuju veću otpornost premaza na UV zračenje. Da bi premazi imali takva svojstva dodaju im se apsorberi u nano veličinama. U ovom radu je ubrzanim izlaganjem ispitano kako vremenski uvjeti utječu na promjenu određenih svojstava poliakrilatnih nanopremaza. Ispitivala su se svojstva: boja, sjaj i tvrdoća površine, te debljina filma premaza.

Abstract (english)

Wood as a natural material is subject to decomposition under the influence of weather conditions. One of the most significant factors is UV radiation, which by its action chemically decomposes wood and affects changes in its properties such as: color, shine, surface hardness. Therefore, wood is protected with various coatings in order to extend its life and to keep certain properties longer. With such coatings, there is a need for properties that make the coating more resistant to UV radiation. In order for coatings to have such properties, absorbers in nano sizes are added to them. In this paper, accelerated exposure was used to examine how weather conditions affect the change in certain properties of the polyacrylate nanocoating. The properties were tested: color, gloss and hardness of the surface, as well as the thickness of the coating film.
