Embodiment 1
[0014] A multifunctional modifier for wood impregnation treatment, its components are proportioned by mass percentage: 12% phenol, 15% formaldehyde, 9% phosphoric acid, 8% melamine, 9% urea, 6% zinc borate %, 10% boric acid, 10% sodium octaborate, 5% copper dimethyl dithiocarbamate, 15% silica sol, 1% fatty alcohol polyoxyethylene ether, the mass concentration of formaldehyde is 35wt% ~ 40wt% , the mass concentration of the phosphoric acid is 20wt%-25wt%, and the silicon dioxide content in the silica sol accounts for 20wt%-30wt%.
[0015] Preparation method: (1), weigh each component according to the weight ratio; (2), add phenol and formaldehyde in the reaction kettle in sequence, turn on the stirrer, slowly add sodium hydroxide solution to adjust the pH value to 11-12, And gradually raise the temperature to 55°C-65°C, then add phosphoric acid and ammonium melamine, continue to heat up to 80°C-85°C, keep warm for 1.5-2 hours, then cool down to 70°C-75°C, then add urea, keep w...
