摘　　要：为了改善低密度、幼龄材等低质材的性能,以便能代替天然大径材,缓解我国目前木材的供需矛盾,可通过无机物改性木材而制得无机复合木材来替代天然优质材。采用无机物改性木材,可有效地提高低质木材的力学强度,防腐和阻燃等性能。本文介绍采用无机盐类、无机氧化物(SiO2纳米粒子、Al2O3、TiO2等纳米粒子)和天然矿土等无机材料对木材的改性方法及各种无机改性方法的基本原理,并阐明各种无机改性处理方法对木材材性的影响。In order to improve the performance of low density juvenile wood and other low-quality materials to replace the natural large-diameter timber and to alleviate the present contradiction between timber supply and demand,inorganic wood composites can be produced by modifying wood products with inorganic substance to replace the natural high quality materials.Wood modification by inorganic substance can effectively improve the mechanical strength,corrosion,and flame retardant properties of the low-quality wood.Methods of wood inorganic modification by inorganic salt,inorganic peroxid(nanoparticles SiO2 、Al2O3、TiO2)and ores soil were introduced in this paper,and the basic principle of various inorganic modification and the influences on wood properties for each method of inorganic modification were elaborated.
