英文摘要： The research takes inorganic non-metallic materials as modified materials, through impregnation and high-temperature processing technology, obtaining a performance modified wood - inorganic modified and high temperature treated wood. Through a single factor and orthogonal experimental analysis methods, physical and mechanical properties as indicators, the main impact parameter and the optimum process parameters of the inorganic modified high temperature treatment wood preparation were studied. The each performance of the inorganic modified and high temperature treated wood is detected and evaluated. The change of hemicellulose, cellulose and lignin of the inorganic modified and high temperature treated wood and the binding mode of the inorganic materials and wood are investigated. The modification mechanism of the inorganic modified and high temperature treated wood is revealed. The research plays an important role in promoting the development and utilization of the new eco-friendly wood materials.
