Embodiment 1
[0035] A flame-retardant reinforced wood, which is made by soaking the wood in a wood modifier and vacuum impregnating treatment under vacuum pressure, controlling the vacuum degree to -0.3-0.8MPa, and the pressure to 0.5-1.5MPa. The time is 1.5-3 hours to obtain vacuum-impregnated wood; the vacuum-impregnated wood is dried to obtain flame-retardant reinforced wood.
[0036]The above-mentioned wood modifier is composed of the following raw materials in parts by weight: 5 parts of triazole compounds, 20 parts of hydroxyethyl methacrylate, 0.8 parts of catalyst n-butyllithium, 20 parts of ammonium dihydrogen phosphate, nonionic surface active 20 parts of agent, 3 parts of silicon dioxide powder, 3 parts of silane coupling agent, 6 parts of flame retardant, 90 parts of polyethylene glycol and 900 parts of water, and its preparation method comprises the following specific steps:
[0037] (1) Divide polyethylene glycol into three equal parts and add in two times;
[0038] (2) Add ...
