Effect of bio‐oil and epoxidized linseed oil on physical, mechanical, and biological properties of treated wood

Abstract

In this article, the effects of bio‐oil and epoxidized linseed oil (ELO) on water absorption, tangential swelling, decay and insect resistance, thermo‐gravimetric analysis, and mechanical properties of treated wood samples were studied. The bio‐oil used in this article was by‐product of ThermoWood thermal modification process. Linseed oil and hydrogen peroxide were used to prepare ELO. The results indicated that the samples treated with bio‐oil had lower water absorption than that of the control group. The second treatment with ELO significantly reduced further the water absorption. The decay resistance of treated wood samples with 20% of bio‐oil against brown (Coniophora puteana) and white rot (Trametes versicolor) fungi was very high. According to the insect test results, increasing bio‐oil concentration from 10% to 20% significantly decreased surviving rate of Hylotrupes bajulus. Thermo‐gravimetric analysis showed that all treated samples had higher initial deterioration temperature than that of the control group. Regarding the wood strength, the impregnated bio‐oil generally reduced the mechanical properties of wood except modulus of elasticity (MOE). © 2013 Wiley Periodicals, Inc. J. Appl. Polym.

New environmentally friendly composite laminates with epoxidized linseed oil (ELO) and slate fiber fabrics

“…ELO can be crosslinked as any conventional epoxy resin by using amines [23,27] and anhydrides [28,29]. In the last years some researches have focused on the use of ELO as matrix for composite materials in combination with different reinforcements [29][30][31] . 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 4 The research reported here focuses on the development of environmentally friendly composite laminates based on epoxidized linseed oil (ELO) matrix and slate fabrics obtained from slate fibers manufactured by melt spinning from wastes.…”

Novel hydrophobization of wood by epoxidized linseed oil. Part 1. Process description and anti-swelling efficiency of the treated wood

“…There are only a few publications dealing with ELO for wood protection (Panov et al 2010;Terziev and Panov 2011;Temiz et al 2013). For example, Terziev and Panov (2011) reported the anti-swelling efficiency (ASE) of pinewood in the range of 50-60%, with oil retentions of only 80-120 kg m -3 .…”

“…This efficiency improvement is not enough in-ground use. Temiz et al (2013) carried out a test with larvae of the house longhorn beetle (Hylotrupes bajulus) and concluded that ELO (at 200 kg m -3 retention) could increase the growth and survival rate of larvae. Panov et al (2010) studied the hydrophobic properties of linseed oil, ELO, tall oil ester, and epoxidized tall oil esters in combination with ELO and acetic acid (AA) as catalyst mixed at a ratio of 7:3 (by wt.).…”

Durability of Epoxi-Oil Modified and Alkoxysilane Treated Wood in Field Testing

“…There is an opportunity to link any plant oil to the wood cell wall and accelerate polymerisation reaction by epoxidizing the oil and subsequently impregnating it in the presence of a catalyst (Treu et al 2004;Temiz et al 2007Temiz et al , 2013. Few publications on the use of epoxidised oils for wood protection were found in the literature.…”

“…Few publications on the use of epoxidised oils for wood protection were found in the literature. Recently, investigations on the protective properties of ELO have been carried out (Panov et al 2010;Terziev and Panov 2011;Temiz et al 2013), and some promising results were reported. For instance, Terziev and Panov (2011) reported anti-swelling efficiency (ASE) of wood within the range of 50 to 60%, achieved with oil retention of only 80 to 120 kg/m 3 .…”
