[0019] A method for preparing insect-resistant wood, the method comprising the steps of:
[0020] (1) Soak the wood in ammonium bicarbonate solution, and let it stand at 20-25°C for 70 minutes, take out the soaked wood, put it in 60-65°C to dry for 2 hours, collect the dried wood, and put the dried wood The wood is soaked in the primary treatment solution, and the primary treatment is performed for 1 to 3 hours;
[0021] (2) After the primary treatment is completed, take out the wood and dry it naturally for 1 to 2 days to obtain the primary treated wood, completely soak the primary treated wood in the secondary treatment solution, and adjust the pH value of the secondary treatment solution to 8.5 ~9.0, carry out shaking secondary treatment at 70~75℃ for 1~2h;
[0022] (3) Take out the wood after shaking the secondary treatment, and then completely soak it in the tertiary treatment solution. Level, the amount added is 0.2-0.4% of the wood mass in the third-level treatment so...
