Abstract

 The aim of this Study was to investigate on the effect of using vegetable oil containing UV absorbent as coating on the weathering resistance of heat treated wood. For this purpose, 180 gr/m2 of vegetable oil (linseed or soybean) containing 0 and 0. 5 wt% of UV absorbent (nano ZnO or Tinvin 326) was applied to the surface of the specimens by brush. The weathering resistance of these specimens after six months of Natural weathering was examined by colorimetry, roughness, ATR-FTIR spectroscopy and stereomicroscope. The results of colorimetry indicated that in the first month of weathering, coatings containing soybean oil had less color changes than coatings containing linseed oil. But at the end of the weathering, But at the end of the weathering, specimens coated with linseed oil (pure and containing nano ZnO) and soybean oil containing nano ZnO had the least color changes compared to other treatments. The results of the roughness test revealed that the oil coatings have partially reduced surface roughness increasing due to weathering but the UV absorbents did not have a positive effect in this regard. Stereomicroscope images also indicate that coated heat treated wood specimens had less surface degradation and surface crack than uncoated specimens.
