Embodiment 1
[0017] A method for improving the durability of fast-growing wood furniture. The prepared silane-modified polyether emulsion and silica sol are used to prepare a fast-growing wood impregnation treatment solution, which is subjected to hydrothermal pressure impregnation to obtain modified fast-growing wood for further processing to prepare wooden furniture;
[0018] Concretely, the preparation method of modified fast-growing wood comprises the following process steps:
[0019] S1: Preparation of silane-modified polyether emulsion: Measure 170 ml of deionized water into a beaker, place it on a magnetic stirrer to preheat to 44°C, add 5 g of polyethylene glycol and 2 g of maleic anhydride to the beaker, Stir until the solid dissolves, then add 30 ml of polyether aqueous solution with a mass concentration of 20% to the beaker, stir and mix evenly, transfer the mixture to a three-necked flask, add 0.4 gram of wetting agent and 0.2 gram of emulsifier to the flask, stir Mix evenly an...
