Method for preparing room temperature cured multifunctional wood modifier and method for wood modification

A method for preparing an ambient temperature cured multifunctional wood modifier, comprising the following steps:

• step 1:
• weighing 1%-50% of hydrophobic polymer resin, 0.1%-1% of additive, 0.1%-10% of curing agent and the balance solvent according to weight percent respectively, mixing and then stirring at an ambient temperature for at least 2 h to obtain a functional reagent A;
• step 2:
• weighing 0.1%-5% of nanoparticles, 0.1%-2% of surface modifier and the balance toluene according to weight percent respectively, mixing and then stirring for 72-76 h, cleaning with acetone, centrifuging at 8000-9000 rpm for 3-5 times, and drying at 78-82° C. for 12-14 h to obtain a functional reagent B;
• step 3:
• adding a functional reagent C into the functional reagent A, evenly stirring, adding the functional reagent B, and performing ultrasonic processing for at least 30 min to obtain the multifunctional wood modifier, wherein the weight of the functional reagent B is 0.1%-1% that of the functional reagent A, and the weight of the functional reagent C is 0.2%-2% that of the functional reagent A.
