摘要

亚麻籽油是一种常用的木材处理剂,在使用过程中常与环烷油混用。在本研究中,我们开发了一种新型的亚麻油共混物,其中环烷油被醇和裂解油取代。混相试验表明,亚麻籽油可以与含有三个或更多碳原子的伯醇无限混合。此外,还发现了由亚麻籽油、醇和热解油组成的三组分混合物的动力学稳定性。进一步测试了所开发的共混物的粘度和溶剂蒸发速率。最后,对木材进行了浸渍试验。处理油的吸收率和防水性效果各不相同,用丙醇和裂解油替代白酒具有潜力。后者在浓度为37.5%的1-或2-丙醇和12.5%的热解油中与50% (wt)的亚麻籽油混溶。与对照情况相比,用该药剂处理明显降低了木材的吸水性。因此,我们的研究认为新开发的亚麻籽油混合物具有很大的潜力,它可能会引入额外的产品特性,并通过热解为副产品创造价值。

Alternative wood treatment with blends of linseed oil, alcohols and pyrolysis oil

Linseed oil is a common wood treatment agent, which is often blended with naphthenic oil during its application. In this study, we developed new types of linseed oil blends, where the naphthenic oil was substituted with alcohols and pyrolysis oil. As miscibility tests revealed, linseed oil can be blended indefinitely with primary alcohols containing three carbon atoms or more. In addition, kinetic stability of three-component-mixtures was found, which comprised linseed oil, alcohol and pyrolysis oil. The developed blends were further tested for their viscosity and rate of solvent evaporation. At last, trial impregnations of wood were done to test this new treatment agent. The uptake of treatment oil and the effect on water repellency varied, and substituting white spirit with propanol and pyrolysis oil showed potential. The latter were miscible with 50% (wt) linseed oil at concentrations of 37.5% 1- or 2-propanol and 12.5% pyrolysis oil. Compared with the reference case, treatment with this agent markedly decreased the water-uptake of the wood. Our study hence attributes great potential to the newly developed linseed oil blends, which may introduce additional product characteristics and generate value to byproducts via pyrolysis.
