| Özet |
| Aim of study: To determine the scratch resistance of water-based varnishes modified with nanoparticles against accelerated UV aging effect in some ThermoWood materials. Material and methods: American ash (Fraxinus americana) and scotch pine (Pinus sylvestris Lipsky) wood were heat treated at a temperature of 190 C for 1, 5 hours and 212 C for 2 hours. Later twocomponent water-based varnishes, with D70-D99 commercial codes, modified with 1%, 3% and 5% ZnO and hollow ceramic spherical (HCS) nanoparticles were applied to the sample surfaces. And then the samples were then subjected to accelerated aging for 240 hours according to ASTM G154. The scratch resistance of varnish layers was determined by TS EN 15186 principles. Main results: ZnO and HCS nanoparticles used for modifying water-based varnishes increased the scratch resistance in D99 and decreased in D70.Highlights: In D99 varnish, ZnO and HCS additive increased scratch resistance. When it is desired to increase the resistance against mechanical effects, especially 5% ZnO and HCS additives can be recommended. At the same time, new studies with different additive ratios of different nanoparticles can be suggested to increase scratch resistance in water-based varnishes. |
