| description | The invention discloses a wood preservative modification treatment method. The wood preservative modification treatment method is characterized in that wood is treated by using a chemical agent containing quercetin and oxalic acid, wherein the quercetin is grafted to the cell wall of the wood through the oxalic acid. The specific method comprises the steps that 5-20 parts of quercetin and 2-50 parts of oxalic acid are weighed and dissolved in 150-300 parts of absolute ethyl alcohol, 0.4-2 parts of p-toluenesulfonic acid is added, and the chemical agent for treating wood is formed; the wood tobe treated is soaked for 48-96 h at normal temperature and normal pressure; and the impregnated wood blocks are placed in the environment of 120 DEG C to be treated for 2-8 h. According to the method,effective chemical bond combination can be formed between quercetin and wood cell walls, the durability of wood is improved, the loss resistance of the wood is improved, the technical problem that quercetin serving as a botan |
