植物油改性木材研究进展

Research Progress of Vegetable Oil Modified Wood

植物油是橄榄油、蓖麻油等不干性油,棉籽油、大豆油等半干性油和桐油、亚麻油等干性油的统称。植物油具有良好的疏水性和导热性,是一种颇具潜力的环保型木材改性剂。目前,利用植物油改性木材已取得了一定的研究成果。文中介绍了植物油的组成、类型及植物油改性木材的方法,并综述植物油改性后改性剂的渗透与分布及其对改性材的疏水性、吸湿性、尺寸稳定性、抗生物劣化性、力学性能及耐老化性能的影响,讨论了植物油改性木材的不足并提出了研究展望,以期对今后该领域的研究工作有所启发。

Vegetable oil is a general term for non-drying oil such as olive oil and castor oil, semi-drying oil such as cotton oil and soybean oil and drying oil such as Tung oil and linseed oil. It is quite a potential environmentally friendly wood modifier due to its good hydrophobicity and thermal conductivity. So far, wood modification with vegetable oil has achieved certain positive results. In this paper, the basic composition, type of vegetable oil and different approaches of vegetable oil treatment on wood are introduced. The penetration and distribution of modifiers, hydrophobicity, hygroscopicity, dimensional stability, biodegradation resistance, mechanical properties and aging resistance of vegetable oil treated wood are reviewed. Finally, the existing shortcomings and research prospects of vegetable oil modification are discussed, expected to inspire the researchers for future research work.
