Özet
Utilizing natural bioactive compounds to enhance the service life of wood materials is a promising approach from both human health and environmental preservation perspectives. In recent years, significant efforts have been made to explore, develop, and refine new organic compounds for use in bio-composite production and wood preservation. In this study, pentaerythritol ester rosin (PEK) was synthesized and combined with epoxidized soybean oil (ESO) and Pinus sylvestris L. wood samples were impregnated with this solution prepared at different concentrations. Since PEK is prone to leaching from wood, it was blended with epoxidized vegetable oils to create a synergistic effect, ensuring stronger chemical bonding with the hydroxyl groups in wood. Various physical, chemical tests and analyses were conducted on the impregnated wood samples to evaluate their performance. The results showed that 20.0% PEK + ESO impregnation mixture was the most effective mixture for dimensional stability. This bio-based preservative system aims to extend the service life of woods while reducing reliance on petroleum-derived chemicals and heavy metals, thereby lowering the environmental footprint of wood protection.
