dc.description.abstract | U radu je ispitan uticaj vrste završnog premaza na osnovna mehanička svojstva lakirane površine: utiskujuću tvrdoću, otpornost na grebanje i otpornost na abraziju. Korišćene su tri vrste završnog premaza: 2K poliuretanski premaz, 2K akril-izocijanatni premaz i 2K alkid-uretanski premaz. Da bi se utvrdilo da li drvna vrsta, koja nije u neposrednom kontaktu sa završnim premazom, ima uticaja na mehanička svojstva lakirane površine u ispitivanju su korišćeni uzorci dve drvne vrste: smrče (Picea abies Karst.) i hrasta (Quercus robur L.). Najviše vrednosti utiskujuće tvrdoće pokazali su uzorci lakirani 2K akril-izocijanatnim premazom, kod obe drvne vrste (1,34 N za smrču; 1,4 N za hrast), dok su najviše vrednosti otpornosti na grebanje (20 N kod obe drvne vrste) i otpornosti na abraziju (gubitak mase premaza od 480 mg nakon 700 ciklusa kod obe drvne vrste) pokazali uzorci lakirani 2K alkid-uretanskim premazom. Ispitivanja su pokazala da drvna vrsta nema uticaja na vrednosti utiskujuće tvrdoće, otpornosti na grebanje i otpornosti na abraziju lakirane površine. | sr |
dc.description.abstract | This paper investigates the impact of the top coating on the basic mechanical properties of a lacquered surface, including indentation hardness, scratch resistance and abrasion resistance. Three types of the top coating were used, including a 2K polyurethane coating, a 2K acrylate-isocyanate coating and a 2K alkyd-urethane coating. Samples of two wood species, spruce (Picea abies Karst.) and oak (Quercus robur L.), were used in this study, in order to determine whether the wood species, which is not in direct contact with the top coating, has an impact on the mechanical properties of a lacquered surface. The samples coated with a 2K acrylate-isocyanate coating showed the highest values of indentation hardness, in the samples of both wood species (1.34 N for spruce; 1.4 N for oak). The samples coated with a 2K alkyd-urethane coating showed the highest values of scratch resistance (20 N for both wood species) and abrasion resistance (mass loss of 480 mg after 700 cycles for both wood species). The results have shown that the wood species does not affect the value of indentation hardness, scratch resistance and abrasion resistance of a lacquered surface. | en |
