Utilisation of chemically modified lampante oil for wood protection

Abstract

Within the Slovenian region of Istria, the olive growing and oil production industry is strong. This industry has a long history and the olives grown here have high levels of biologically active compounds including a variety of phenolic compounds. Using residual materials generated by this industry in potential wood protection systems would not only valorise low-value materials and stimulate rural economies but would also provide an alternative to currently used oil-based protection systems. The objective of this study was to produce an oil treatment for wood protection and assess its efficacy in reducing leaching, weathering effects, and fungal decay. Two maleinisation techniques were used to chemically modify low-value lampante oil in an attempt to limit leaching when impregnated in wood. Pinus sylvestris (Scots pine) and Fagus sylvatica (European beech) were treated with the modified oils and underwent leaching, accelerated weathering, and decay tests. Leaching of the treatment oils was relatively low compared with other experiments and beech wood specimens treated with a direct maleinisation treatment showed improvement in performance compared to control specimens. In addition, it was found that the modified oils were not completely removed from the wood after solvent extraction indicating that they could potentially be used as an immobilisation agent in combination with other treatments thereby reducing the amount of active component of the protective agent.

Lavender oil as eco-friendly alternative to protect wood against termites without negative effect on wood properties

“…Using of vegetable oils as a solvent medium for lavender EOs can be a sound alternative thanks to hydrophobic and repellent effect of this oil itself 52 , 79 , 80 . Another possibility is using only the most active substances presented in lavender EOs, natural or synthetic.…”

Surface Wettability Of Boron And Oil-Treated Wood

“…Treatments with environmentally friendly and biodegradable oils are known to reduce capillary water uptake by creating a protective layer on the wood surface (Lee et al, 2018;Schwarzkopf et al, 2018). Since oil treatment improves the hydrophobicity of the wood surface, the rate of water absorption is limited and the risk or rate of fungal attack is reduced (Koski, 2008;Temiz et al, 2008a;Tomak et al, 2011b;Jebrane et al, 2015;Demirel et al, 2018).…”

Development of Safe Formulations for Wood Processing Based on Vegetable Oil Waste

“…В исследованиях [3][4][5][6] приводятся результаты разработки пропиточных составов на основе льняного, подсолнечного и других растительных масел с целью получения композитных материалов на основе древесины, используемых в строительстве и быту. Авторами [7] изучено влияние времени обработки горячими растительными маслами на физико-механические свойства древесины дуба.…”
