Method for imitating material color of precious material by fast-growing wood

The invention discloses a method for simulating the material color of a precious material by fast-growing wood, which comprises the following operation steps: (1) immersing eucalyptus into a cobalt nitrate aqueous solution, carrying out vacuum impregnation, pouring into a 2-methylimidazole solution after the impregnation is completed, and stirring to obtain Co-MOF-Wood; and (2) the Co-MOF-Wood obtained in the step (1) is soaked in a MnCl2 solution with the concentration being 0.016 mol/L to 0.064 mol/L, then heating and stirring are conducted at the temperature of 20 DEG C to 80 DEG C, and the eucalyptus veneer with the cobalt-manganese double hydroxide coating, namely the fast-growing wood imitating the pteroceltis purpurea color material color, is prepared. The color matching treatment process used in the method is safe, environmentally friendly and mild in condition, the decoration effect and the product value of wood products can be improved, and efficient utilization of artificial forest wood is achieved
