人工林木材密度较低、材质较差、防护性能弱,应用范围受到极大的限制。低分子量树脂处理是提高人工林木材各项性质、增加其附加值的有效途径。作者综述了国内外近年来树脂改性的研究进展,对改性工艺、改性前后木材的各项性能变化以及改性机理研究进行了详细评述,并总结了树脂在木材中的存在状态以及与细胞壁的结合情况,最后提出了本领域的发展趋势,以便为木材树脂改性的进一步研究提供参考。
Plantation wood density is lower, the material is poor, weak protective properties, the application is greatly restricted. Low molecular weight resin treatment is to improve the properties of plantation wood, an effective way to increase its added value. The author reviewed the research progress of resin modification in recent years at home and abroad, reviewed the modification of the wood properties and the modification mechanism before and after the modification, and summarized the existing state of the resin in wood Finally, the development trends in the field are proposed to provide reference for further study on the modification of wood resin.
